The present specification provides different embodiments to illustrate the technical features of different embodiments of the present invention. Wherein, the configuration of each element in the embodiment is for illustration, and not for limiting the present invention. In addition, parts of the reference numerals in the drawings in the embodiments are repeated for the purpose of simplifying the description, and do not mean the correlation between different embodiments.

图1为本发明操作系统的一可能示意图。如图所示,操作系统100包括一电子装置110、一主机板120以及一屏幕130。在本实施例中,当电子装置110耦接主板120时,主机板120输出一图像信号SI。屏幕130根据图像信号SI,显示一充电画面,用以供使用者点选。在使用者选择充电画面里的一充电选项后,主机板120输出一相对应的充电电源,用以对电子装置110充电。本发明并不限定电子装置110的种类。在一可能实施例中,电子装置110为一便携式电子装置,如智能手机或是平板。FIG. 1 is a possible schematic diagram of the operating system of the present invention. As shown in the figure, the operating system 100 includes an electronic device 110 , a motherboard 120 and a screen 130 . In this embodiment, when the electronic device 110 is coupled to the mainboard 120 , the mainboard 120 outputs an image signal SI. The screen 130 displays a charging screen according to the image signal SI for the user to select. After the user selects a charging option in the charging screen, the motherboard 120 outputs a corresponding charging power source for charging the electronic device 110 . The present invention does not limit the type of the electronic device 110 . In a possible embodiment, the electronic device 110 is a portable electronic device, such as a smart phone or a tablet.

主机板120至少包括一充电电路121、一中央处理器122、一存储器123、一图像处理电路124以及一连接接口125。在一可能实施例中,当电子装置110耦接连接接口125时,充电电路121告知中央处理器122。中央处理器122执行存储器123所储存的一充电程序,用以产生一控制信号SC。图像处理电路124根据控制信号SC产生一图像信号SI。屏幕130根据图像信号SI呈现一充电画面。The motherboard 120 at least includes a charging circuit 121 , a central processing unit 122 , a memory 123 , an image processing circuit 124 and a connection interface 125 . In a possible embodiment, when the electronic device 110 is coupled to the connection interface 125 , the charging circuit 121 informs the central processing unit 122 . The central processing unit 122 executes a charging program stored in the memory 123 to generate a control signal SC. The image processing circuit 124 generates an image signal SI according to the control signal SC. The screen 130 presents a charging picture according to the image signal SI.

屏幕130所呈现的充电画面具有许多充电选项。使用者根据本身的电子装置的厂牌,选择合适的充电选项。中央处理器122根据使用者所选择的充电选项,命令充电电路121输出合适的充电电源。由于充电电路121支持多种充电协定,故使用者仅需利用一条连接线便可将电子装置110接上主机板120进行快充。因此,使用者不需要额外购买特定的充电器。The charging screen presented by screen 130 has a number of charging options. The user selects an appropriate charging option according to the brand of his own electronic device. The central processing unit 122 instructs the charging circuit 121 to output an appropriate charging power source according to the charging option selected by the user. Since the charging circuit 121 supports various charging protocols, the user only needs to use one connection cable to connect the electronic device 110 to the motherboard 120 for fast charging. Therefore, the user does not need to purchase a specific charger additionally.

另外,即使主机板120处于一省电模式(如高级配置电源接口(AdvancedConfiguration and Power Interface;ACPI)规范中的S3(Suspend to RAM)或S4(Suspendto Disk))时,充电电路121仍可持续对电子装置110充电。再者,藉由屏幕130所呈现的充电画面,使用者可根据自身需求选择合适的充电选项,使用者亦可控制充电时间,以避免电子装置的电池过度充电。稍后将通过图2A及图3A说明屏幕130所呈现的充电画面。In addition, even when the motherboard 120 is in a power saving mode (such as S3 (Suspend to RAM) or S4 (Suspend to Disk) in the Advanced Configuration and Power Interface (ACPI) specification), the charging circuit 121 can continue to The electronic device 110 is charged. Furthermore, with the charging screen displayed on the screen 130, the user can select an appropriate charging option according to his own needs, and the user can also control the charging time to avoid overcharging the battery of the electronic device. The charging screen presented by the screen 130 will be described later with reference to FIGS. 2A and 3A .

本发明并不限定充电电路及连接接口的数量。在其它实施例中,主机板120更包括连接接口126以及充电电路127。当电子装置140耦接连接接口126时,屏幕130呈现一充电画面供使用者选择。充电电路127根据使用者所选择的充电选项,输出充电电源予电子装置140。在一可能实施例中,充电电路121输出的充电电源可能相同或不同于充电电路127输出的充电电源。The present invention does not limit the number of charging circuits and connection interfaces. In other embodiments, the motherboard 120 further includes a connection interface 126 and a charging circuit 127 . When the electronic device 140 is coupled to the connection interface 126 , the screen 130 presents a charging screen for the user to select. The charging circuit 127 outputs charging power to the electronic device 140 according to the charging option selected by the user. In a possible embodiment, the charging power output by the charging circuit 121 may be the same as or different from the charging power output by the charging circuit 127 .

本发明并不限定屏幕130的种类。在一可能实施例中,屏幕130可能为一触控屏幕。在此例中,使用者可利用手指直接点选屏幕130所呈现的充电选项。在其它实施例中,使用者可能利用其它输入装置(如键盘或鼠标),间接地点选屏幕130所呈现的充电选项。The present invention does not limit the type of the screen 130 . In a possible embodiment, the screen 130 may be a touch screen. In this example, the user can directly click on the charging options displayed on the screen 130 with a finger. In other embodiments, the user may use other input devices (eg, a keyboard or a mouse) to indirectly select charging options presented on the screen 130 .

在一可能实施例中,主机板120与屏幕130整合在单一电子装置中,如笔记本电脑。在其它实施例中,主机板120设在一机壳中,并通过一传输线电性连接屏幕130。本发明并不限定传输线的种类。在一可能实施例中,主机板120与屏幕130之间的传输线为一视频图形阵列(Video Graphics Array;VGA)传输线、一数字视频接口(Digital Visual Interface;DVI)传输线、一高画质多媒体接口(High Definition Multimedia Interface;HDMI)传输线。In a possible embodiment, the motherboard 120 and the screen 130 are integrated into a single electronic device, such as a notebook computer. In other embodiments, the motherboard 120 is disposed in a casing, and is electrically connected to the screen 130 through a transmission line. The present invention does not limit the type of transmission line. In a possible embodiment, the transmission line between the motherboard 120 and the screen 130 is a Video Graphics Array (VGA) transmission line, a Digital Visual Interface (DVI) transmission line, and a high-definition multimedia interface. (High Definition Multimedia Interface; HDMI) transmission line.

图2A为屏幕131所呈现的充电画面的一可能示意图。如图所示,充电画面210包括一标准充电选项211、一第一快充选项212以及一第二快充选项213。图2B为图2A的操作示意图。当使用者点选标准充电选项211时,主机板120的一控制器(如中央处理器122)命令充电电路121提供一第一充电电源予电子装置110。在本实施例中,第一充电电源符合USB开发者论坛(USBImplementers Forum;USB-IF)的规范。举例而言,第一充电电源的功率可能约为2.5W。此时,主机板120的所有元件操作于一正常模式(如ACPI规范中的S0)。FIG. 2A is a possible schematic diagram of the charging screen displayed on the screen 131 . As shown in the figure, the charging screen 210 includes a standard charging option 211 , a first fast charging option 212 and a second fast charging option 213 . FIG. 2B is a schematic diagram of the operation of FIG. 2A . When the user selects the standard charging option 211 , a controller of the motherboard 120 (eg, the central processing unit 122 ) instructs the charging circuit 121 to provide a first charging power source to the electronic device 110 . In this embodiment, the first charging power source conforms to the specification of the USB Developer Forum (USB Implementers Forum; USB-IF). For example, the power of the first charging power source may be about 2.5W. At this time, all components of the motherboard 120 operate in a normal mode (eg, S0 in the ACPI specification).

然而,当主机板120的一特定元件(如中央处理器122)离开正常模式并进入一省电模式(如ACPI规范中的S3或S4)时,充电电路121可能调整或不调整第一充电电源。在一可能实施例中,充电电路121可能维持或减少第一充电电源,或是停止提供第一充电电源。在另一实施例中,充电电路121可能根据电子装置110所产生的一信号,输出一唤醒信号,用以唤醒进入省电模式的特定元件。在其它实施例中,充电电路121不输出任何唤醒信号。因此,电子装置110无法通过充电电路121唤醒进入省电模式的特定元件。However, when a specific element of the motherboard 120 (eg, the CPU 122 ) leaves the normal mode and enters a power saving mode (eg, S3 or S4 in the ACPI specification), the charging circuit 121 may or may not adjust the first charging power source . In a possible embodiment, the charging circuit 121 may maintain or reduce the first charging power, or stop providing the first charging power. In another embodiment, the charging circuit 121 may output a wake-up signal according to a signal generated by the electronic device 110 to wake up a specific device entering the power saving mode. In other embodiments, the charging circuit 121 does not output any wake-up signal. Therefore, the electronic device 110 cannot wake up the specific element entering the power saving mode through the charging circuit 121 .

当使用者选择第一快充选项212时,主机板120命令充电电路121提供一第二充电电源予电子装置110。在一可能实施例中,充电电路121根据一快速充电2.0(Quick charge2.0;QC 2.0)协定或是一快速充电3.0(Quick charge 3.0;QC 3.0)协定提供第二充电电源。以快速充电3.0为例,当电子装置110接收到第二充电电源时,大约35分钟后,电子装置110的电量可从0%增加至80%。在本实施例中,第二充电电源大于第一充电电源。举例而言,第二充电电源的功率约为18W。此时,主机板120操作在正常模式。在一些实施例中,当主机板120的一特定元件进入一省电模式时,充电电路121可能减少第二充电电源,如从18W减少至5W。在其它实施例中,当使用者选择第一快充选项212时,电子装置110无法通过充电电路121唤醒进入省电模式的特定元件。When the user selects the first fast charging option 212 , the motherboard 120 instructs the charging circuit 121 to provide a second charging power source to the electronic device 110 . In a possible embodiment, the charging circuit 121 provides the second charging power source according to a Quick Charge 2.0 (Quick charge 2.0; QC 2.0) protocol or a Quick Charge 3.0 (Quick charge 3.0; QC 3.0) protocol. Taking Quick Charge 3.0 as an example, when the electronic device 110 receives the second charging power source, the power of the electronic device 110 can be increased from 0% to 80% after about 35 minutes. In this embodiment, the second charging power source is larger than the first charging power source. For example, the power of the second charging power source is about 18W. At this time, the motherboard 120 operates in the normal mode. In some embodiments, when a specific element of the motherboard 120 enters a power saving mode, the charging circuit 121 may reduce the second charging power source, eg, from 18W to 5W. In other embodiments, when the user selects the first fast charging option 212 , the electronic device 110 cannot wake up specific components that enter the power saving mode through the charging circuit 121 .

当使用者选择第二快充选项213时,充电电路121判断电子装置110是否属于一特定装置,如苹果(Apple)公司所生产的iPhone 8、iPhone X或是iPad Pro。当电子装置110并非iPhone 8、iPhone X或是iPad Pro时,充电电路121提供一第三充电电源予电子装置110。当电子装置110为苹果(Apple)公司所生产的iPhone 8、iPhone X或是iPad Pro时,充电电路121提供一第四充电电源予电子装置110。在一可能实施例中,第四充电电源大第三充电电源。举例而言,第三充电电源约为12W,第四充电电源约为15W。在一些实施例中,当电子装置110接收到第三或第四充电电源时,大约在30分钟内,电子装置110的电量可达50%。When the user selects the second fast charging option 213, the charging circuit 121 determines whether the electronic device 110 belongs to a specific device, such as iPhone 8, iPhone X or iPad Pro produced by Apple. When the electronic device 110 is not an iPhone 8, an iPhone X or an iPad Pro, the charging circuit 121 provides a third charging power source to the electronic device 110. When the electronic device 110 is iPhone 8, iPhone X or iPad Pro produced by Apple, the charging circuit 121 provides a fourth charging power source to the electronic device 110. In a possible embodiment, the fourth charging power source is larger than the third charging power source. For example, the third charging power source is about 12W, and the fourth charging power source is about 15W. In some embodiments, when the electronic device 110 receives the third or fourth charging power source, the power of the electronic device 110 can reach 50% in about 30 minutes.

在其它实施例中,当主机板120的一特定元件操作于一省电模式时,充电电路121提供一第五充电电源予电子装置110。在本实施例中,第五充电电源小于第三及第四充电电源。在一可能实施例中,第五充电电源约为5W。此时,电子装置110无法通过充电电路121唤醒进入省电模式的特定元件。In other embodiments, when a specific element of the motherboard 120 operates in a power saving mode, the charging circuit 121 provides a fifth charging power source to the electronic device 110 . In this embodiment, the fifth charging power source is smaller than the third and fourth charging power sources. In a possible embodiment, the fifth charging power source is about 5W. At this time, the electronic device 110 cannot wake up the specific element entering the power saving mode through the charging circuit 121 .

在其它实施例中,充电画面210更包括一时间设定选项214(如图2A所示)。当使用者选择时间设定选项214,并输入一充电时间时,充电电路121根据使用者所输入的充电时间,提供充电电源予电子装置110。举例而言,假设使用者输入的充电时间为1小时。在此例中,当充电电路121输出充电电源的时间达1小时时,充电电路121停止输出充电电源,以避免电子装置110内部的充电电池过度充电。In other embodiments, the charging screen 210 further includes a time setting option 214 (as shown in FIG. 2A ). When the user selects the time setting option 214 and inputs a charging time, the charging circuit 121 provides charging power to the electronic device 110 according to the charging time input by the user. For example, assume that the charging time input by the user is 1 hour. In this example, when the charging circuit 121 outputs the charging power for 1 hour, the charging circuit 121 stops outputting the charging power to prevent the rechargeable battery inside the electronic device 110 from being overcharged.

在一可能实施例中,使用者可能先从标准充电选项211、第一快充选项212以及第二快充选项213中选择一者,再选择时间设定选项214,用以限定充电时间。在另一实施例中,使用者可能先选择时间设定选项214,再从标准充电选项211、第一快充选项212以及第二快充选项213中选择一者。在其它实施例中,使用者可能只从标准充电选项211、第一快充选项212以及第二快充选项213中选择一者,而不选择时间设定选项214。In a possible embodiment, the user may first select one of the standard charging option 211 , the first fast charging option 212 and the second fast charging option 213 , and then select the time setting option 214 to limit the charging time. In another embodiment, the user may first select the time setting option 214 and then select one of the standard charging option 211 , the first fast charging option 212 and the second fast charging option 213 . In other embodiments, the user may only select one of the standard charging option 211 , the first fast charging option 212 , and the second fast charging option 213 , but not the time setting option 214 .

在其它实施例中,主机板120可能具有多个连接接口以及多个充电电路,其中每一连接接口耦接一充电电路。在此例中,每当一电子装置插入一连接接口时,屏幕130呈现一相对应的充电画面。举例而言,当第一电子装置插入一第一连接接口时,屏幕130呈现第一充电画面,供使用者选择适合第一电子装置的充电选项。当第二电子装置插入一第二连接接口时,屏幕130呈现第二充电画面,供使用者选择适合第二电子装置的充电选项。第一充电画面可能相同或不同于第二充电画面。在一实施例中,使用者可能点选第一充电画面中的第一快充选项,并点选第二充电画面中的第二快充选项。因此,第一及第二电子装置接收不同的充电电源。In other embodiments, the motherboard 120 may have multiple connection ports and multiple charging circuits, wherein each connection port is coupled to a charging circuit. In this example, whenever an electronic device is plugged into a connection port, the screen 130 presents a corresponding charging screen. For example, when the first electronic device is plugged into a first connection interface, the screen 130 presents a first charging screen for the user to select a charging option suitable for the first electronic device. When the second electronic device is plugged into a second connection port, the screen 130 presents a second charging screen for the user to select a charging option suitable for the second electronic device. The first charging screen may be the same or different from the second charging screen. In one embodiment, the user may click the first fast charging option in the first charging screen, and click the second fast charging option in the second charging screen. Therefore, the first and second electronic devices receive different charging power sources.

图3A为本发明屏幕所呈现的另一画面示意图。如图所示,充电画面310包括一标准充电选项311以及一快充选项312。图3B为图3A的操作示意图。当使用者选择标准充电选项311时,充电电路121提供第一充电电源予电子装置110。此时,如果主机板120的一特定元件进入一省电模式时,充电电路121可能维持或减少第一充电电源。在其它实施例中,充电电路121可能停止提供第一充电电源。在一可能实施例中,此时,充电电路121根据电子装置110所产生的信号,产生一唤醒信号,用以唤醒进入省电模式的特定元件。在另一可能实施例中,充电电路121不产生任何唤醒信号。FIG. 3A is a schematic diagram of another screen presented on the screen of the present invention. As shown in the figure, the charging screen 310 includes a standard charging option 311 and a fast charging option 312 . FIG. 3B is a schematic diagram of the operation of FIG. 3A . When the user selects the standard charging option 311 , the charging circuit 121 provides the first charging power source to the electronic device 110 . At this time, if a specific element of the motherboard 120 enters a power saving mode, the charging circuit 121 may maintain or reduce the first charging power source. In other embodiments, the charging circuit 121 may stop providing the first charging power source. In a possible embodiment, at this time, the charging circuit 121 generates a wake-up signal according to the signal generated by the electronic device 110 to wake up the specific device entering the power saving mode. In another possible embodiment, the charging circuit 121 does not generate any wake-up signal.

当使用者选择快充选项312时,充电电路121判断电子装置110是否为苹果公司的产品。在一可能实施例中,充电电路121根据电子装置110的操作系统,判断电子装置110是否为苹果公司的产品。举例而言,当电子装置110不具有IOS系统时,表示电子装置110并非苹果公司的产品。因此,充电电路121提供第二充电电源予电子装置110。第二充电电源大于第一充电电源。此时,如果主机板120的一特定元件进入一省电模式时,充电电路121可能减少第二充电电源。此时,充电电路121不产生唤醒信号。When the user selects the fast charging option 312, the charging circuit 121 determines whether the electronic device 110 is a product of Apple. In a possible embodiment, the charging circuit 121 determines whether the electronic device 110 is a product of Apple according to the operating system of the electronic device 110 . For example, when the electronic device 110 does not have an IOS system, it means that the electronic device 110 is not a product of Apple. Therefore, the charging circuit 121 provides the second charging power source to the electronic device 110 . The second charging power source is larger than the first charging power source. At this time, if a specific element of the motherboard 120 enters a power saving mode, the charging circuit 121 may reduce the second charging power source. At this time, the charging circuit 121 does not generate a wake-up signal.

当电子装置110具有IOS系统时,表示电子装置110为苹果公司的产品。因此,充电电路121再判断电子装置110是否为一特定装置,如iPhone 8、iPhone X或是iPad Pro。当电子装置110并非为特定装置时,充电电路121提供第三充电电源予电子装置110。当电子装置110为特定装置时,充电电路121提供第四充电电源予电子装置110。When the electronic device 110 has an IOS system, it means that the electronic device 110 is a product of Apple. Therefore, the charging circuit 121 further determines whether the electronic device 110 is a specific device, such as iPhone 8, iPhone X or iPad Pro. When the electronic device 110 is not a specific device, the charging circuit 121 provides a third charging power source to the electronic device 110 . When the electronic device 110 is a specific device, the charging circuit 121 provides a fourth charging power source to the electronic device 110 .

此时,如果主机板120的一特定元件(如图1的122、123或124)进入一省电模式时,充电电路121可能改提供第五充电电源予电子装置110。第五充电电源大于第一充电电源,但小于第三及第四充电电源。在一可能实施例中,当充电电路121提供第五充电电源予电子装置110时,充电电路121不产生任何唤醒信号。At this time, if a specific component of the motherboard 120 (eg 122 , 123 or 124 in FIG. 1 ) enters a power saving mode, the charging circuit 121 may instead provide a fifth charging power source to the electronic device 110 . The fifth charging power source is larger than the first charging power source, but smaller than the third and fourth charging power sources. In a possible embodiment, when the charging circuit 121 provides the fifth charging power source to the electronic device 110, the charging circuit 121 does not generate any wake-up signal.

Since the characteristics of the time setting option 313 are similar to the characteristics of the time setting option 214 in FIG. 2A , the details are not repeated.

In other embodiments, the input power PI is provided by a power supply (not shown). In some embodiments, the voltage conversion circuit 410 stops outputting the charging power PO according to a disable signal STP.

切换电路420耦接连接接口125,并根据切换信号SSW1及SSW2传送引脚D+与D-的信号予控制器430或440。在本实施例中,当切换电路420传送引脚D+与D-的信号予控制器430时,切换电路420不传送引脚D+与D-的信号予控制器440。当切换电路420传送引脚D+与D-的信号予控制器440时,切换电路420不传送引脚D+与D-的信号予控制器430。The switching circuit 420 is coupled to the connection interface 125, and transmits the signals of the pins D+ and D- to the controller 430 or 440 according to the switching signals SSW1 and SSW2. In this embodiment, when the switching circuit 420 transmits the signals of the pins D+ and D- to the controller 430 , the switching circuit 420 does not transmit the signals of the pins D+ and D- to the controller 440 . When the switching circuit 420 transmits the signals of the pins D+ and D- to the controller 440 , the switching circuit 420 does not transmit the signals of the pins D+ and D- to the controller 430 .

本发明并不限定切换电路420的电路架构。在一可能实施例中,切换电路420具有开关421及422。开关421根据切换信号SSW1导通或不导通传输路径PA1。传输路径PA1耦接于连接接口125的引脚D+及D-与控制器440之间。开关422根据切换信号SSW2导通或不导通传输路径PA2。传输路径PA2耦接于连接接口125的引脚D+及D-与控制器430之间。The present invention does not limit the circuit structure of the switching circuit 420 . In a possible embodiment, the switching circuit 420 has switches 421 and 422 . The switch 421 conducts or does not conduct the transmission path PA1 according to the switching signal SSW1.

The switch 422 turns on or off the transmission path PA2 according to the switching signal SSW2. The transmission path PA2 is coupled between the pins D+ and D- of the connection interface 125 and the controller 430 .

控制器430耦接于切换电路420与电压转换电路410之间。在本实施例中,控制器430通过传输路径PA2与电子装置110连通,并根据电子装置110的充电需求,产生触发信号ST2。本发明并不限定控制器430的电路架构。在一可能实施例中,控制器430为一充电识别集成电路。在其它实施例中,控制器430不支持一唤醒功能。因此,控制器430无法根据电子装置110所产生的信号,产生一唤醒信号。The controller 430 is coupled between the switching circuit 420 and the voltage converting circuit 410 . In this embodiment, the controller 430 communicates with the electronic device 110 through the transmission path PA2 , and generates the trigger signal ST2 according to the charging requirement of the electronic device 110 . The present invention does not limit the circuit structure of the controller 430 . In one possible embodiment, the controller 430 is a charge identification integrated circuit. In other embodiments, the controller 430 does not support a wake-up function. Therefore, the controller 430 cannot generate a wake-up signal according to the signal generated by the electronic device 110 .

控制器440耦接于切换电路420与电压转换电路410之间。在本实施例中,控制器440通过传输路径PA1与电子装置110连通,并根据电子装置110的充电需求,产生触发信号ST1。本发明并不限定控制器440的电路架构。在一可能实施例中,控制器440为一平台路径控制器(Platform Controller Hub;PCH)。在另一可能实施例中,控制器440支持一唤醒功能。在此例中,控制器440可根据电子装置110的信号,产生一唤醒信号,用以唤醒主机板120中进入省电模式的特定元件。在其它实施例中,控制器440不支持一唤醒功能。The controller 440 is coupled between the switching circuit 420 and the voltage converting circuit 410 . In this embodiment, the controller 440 communicates with the electronic device 110 through the transmission path PA1 , and generates the trigger signal ST1 according to the charging requirement of the electronic device 110 . The present invention does not limit the circuit structure of the controller 440 . In a possible embodiment, the controller 440 is a platform controller hub (Platform Controller Hub; PCH). In another possible embodiment, the controller 440 supports a wake-up function. In this example, the controller 440 can generate a wake-up signal according to the signal of the electronic device 110 to wake up a specific element of the motherboard 120 that enters the power saving mode. In other embodiments, the controller 440 does not support a wake-up function.

在其它实施例中,控制器440可能通过至少一传输线441与主机板120的部分元件连通。在一可能实施例中,控制器440根据传输线441的信号,得知使用者所选择的充电选项,并根据使用者所选择的充电选项,产生相对应的切换信号SSW1及SSW2。在另一实施例中,切换信号SSW1及SSW2由主机板120的其它元件(如中央处理器)所提供。In other embodiments, the controller 440 may communicate with some components of the motherboard 120 through at least one transmission line 441 . In a possible embodiment, the controller 440 learns the charging option selected by the user according to the signal of the transmission line 441 , and generates corresponding switching signals SSW1 and SSW2 according to the charging option selected by the user. In another embodiment, the switching signals SSW1 and SSW2 are provided by other components of the motherboard 120 (eg, a central processing unit).

当使用者选择图2A的标准充电选项211或是图3A的标准充电选项311时,充电电路121进入一标准充电模式。在此模式下,控制器440通过切换信号SSW1及SSW2,导通传输路径PA1并且不导通传输路径PA2。在一可能实施例中,控制器440不与电子装置110连通,并直接命令电压转换电路410产生一充电电源PO。此时,充电电源PO可称为第一充电电源。在此模式下,不论电子装置110的操作系统是IOS系统或是Andriod系统,充电电路121都会提供第一充电电源,对电子装置110充电。When the user selects the standard charging option 211 of FIG. 2A or the standard charging option 311 of FIG. 3A , the charging circuit 121 enters a standard charging mode. In this mode, the controller 440 turns on the transmission path PA1 and turns off the transmission path PA2 by switching the signals SSW1 and SSW2. In a possible embodiment, the controller 440 is not in communication with the electronic device 110, and directly commands the voltage conversion circuit 410 to generate a charging power source PO. At this time, the charging power source PO may be referred to as a first charging power source. In this mode, regardless of whether the operating system of the electronic device 110 is the IOS system or the Andriod system, the charging circuit 121 will provide the first charging power source to charge the electronic device 110 .

再者,在此模式下,当控制器440得知主机板120的一特定元件进入一省电模式时,控制器440通过触发信号ST1,命令电压转换电路410维持或减少充电电源PO。在其它实施例中,电压转换电路410可能停止提供充电电源PO。在一些实施例中,当控制器440支持一唤醒功能时,电子装置110可通过控制器440唤醒主机板120上的特定元件。Furthermore, in this mode, when the controller 440 knows that a specific element of the motherboard 120 enters a power saving mode, the controller 440 instructs the voltage conversion circuit 410 to maintain or reduce the charging power PO through the trigger signal ST1. In other embodiments, the voltage conversion circuit 410 may stop providing the charging power PO. In some embodiments, when the controller 440 supports a wake-up function, the electronic device 110 can wake up specific components on the motherboard 120 through the controller 440 .

当使用者选择图2A的第一快充选项212时,充电电路121进入一第一快充模式。在此模式下,控制器440不导通传输路径PA1并导通传输路径PA2。因此,控制器430通过传输路径PA2与电子装置110连通,用以得知电子装置110所需的充电电源。接着,控制器430产生触发信号ST2,用以要求电压转换电路410产生充电电源PO。此时,充电电源PO称为第二充电电源。在此模式下,当控制器430得知主机板120的一特定元件进入一省电模式时,控制器430通过触发信号ST2要求电压转换电路410减少充电电源PO。在一可能实施例中,充电电源PO的功率由18W减少至5W。When the user selects the first fast charging option 212 in FIG. 2A , the charging circuit 121 enters a first fast charging mode. In this mode, the controller 440 turns off the transmission path PA1 and turns on the transmission path PA2. Therefore, the controller 430 communicates with the electronic device 110 through the transmission path PA2 to know the charging power required by the electronic device 110 . Next, the controller 430 generates a trigger signal ST2 for requesting the voltage conversion circuit 410 to generate the charging power source PO. At this time, the charging power source PO is referred to as a second charging power source. In this mode, when the controller 430 knows that a specific element of the motherboard 120 enters a power saving mode, the controller 430 requests the voltage conversion circuit 410 to reduce the charging power PO through the trigger signal ST2. In a possible embodiment, the power of the charging power source PO is reduced from 18W to 5W.

本发明并不限定控制器430如何判断主机板120的一特定元件是否进入一省电模式。在一可能实施例中,控制器430通过至少一传输线(未显示)耦接主机板120,用以得知主机板120的一特定元件已进入一省电模式。在其它实施例中,控制器430通过至少一传输线(未显示),接收来自控制器440的一通知信号,用以得知主机板120的一特定元件进入一省电模式。The present invention does not limit how the controller 430 determines whether a specific element of the motherboard 120 enters a power saving mode. In a possible embodiment, the controller 430 is coupled to the motherboard 120 through at least one transmission line (not shown), so as to know that a specific element of the motherboard 120 has entered a power saving mode. In other embodiments, the controller 430 receives a notification signal from the controller 440 through at least one transmission line (not shown) to know that a specific element of the motherboard 120 enters a power saving mode.

当使用者选择图2B的第二快充选项213时,充电电路121进入一第二快充模式。在此模式下,控制器440导通传输路径PA1并且不导通传输路径PA2。此时,控制器440通过传输路径PA1与电子装置110连通,用以得知电子装置110是否为一特定装置。When the user selects the second fast charging option 213 in FIG. 2B , the charging circuit 121 enters a second fast charging mode. In this mode, the controller 440 turns on the transmission path PA1 and does not turn on the transmission path PA2. At this time, the controller 440 communicates with the electronic device 110 through the transmission path PA1 to know whether the electronic device 110 is a specific device.

当电子装置110并非为一特定装置时,控制器440通过触发信号ST1要求电压转换电路410产生充电电源PO。此时,充电电源PO称为第三充电电源。当电子装置110为一特定装置时,控制器440要求电压转换电路410产生充电电源PO。此时,充电电源PO称为第四充电电源。When the electronic device 110 is not a specific device, the controller 440 requests the voltage conversion circuit 410 to generate the charging power PO through the trigger signal ST1. At this time, the charging power source PO is referred to as a third charging power source. When the electronic device 110 is a specific device, the controller 440 requests the voltage conversion circuit 410 to generate the charging power PO. At this time, the charging power source PO is referred to as a fourth charging power source.

在此模式下,当控制器440得知主机板120的一特定元件进入一省电模式时,控制器440不导通传输路径PA1并导通传输路径PA2。此时,控制器430可能先通过传输路径PA2,告知电子装置110充电电源将会被减少。然后,控制器430再通过触发信号ST2要求电压转换电路410减少充电电源PO。此时,充电电源PO称为第五充电电源。In this mode, when the controller 440 knows that a specific element of the motherboard 120 enters a power saving mode, the controller 440 turns off the transmission path PA1 and turns on the transmission path PA2. At this time, the controller 430 may first pass the transmission path PA2 to inform the electronic device 110 that the charging power will be reduced. Then, the controller 430 requests the voltage conversion circuit 410 to reduce the charging power source PO through the trigger signal ST2. At this time, the charging power source PO is referred to as the fifth charging power source.

在一可能实施例中,第五充电电源小于第三及第四充电电源。举例而言,当电子装置110为特定装置时,充电电源PO的功率可能由15W减少至5W。当电子装置110并非特定装置时,充电电源PO的功率可能由12W减少至5W。在其它实施例中,第五充电电源大于第一充电电源。当控制器430不支持唤醒功能时,电子装置110无法通过充电电路121唤醒进入省电模式的元件。在一可能实施例中,使用者需按下一电源开关,才能唤醒进入省电模式的特定元件。在此例中,当特定元件被唤醒时,控制器440导通传输路径PA1并不导通传输路径PA2,用以判断电子装置110是否为特定装置,并根据判断结果命令电压转换电路410重新输出第三或第四充电电源。In a possible embodiment, the fifth charging power source is smaller than the third and fourth charging power sources. For example, when the electronic device 110 is a specific device, the power of the charging power source PO may be reduced from 15W to 5W. When the electronic device 110 is not a specific device, the power of the charging power source PO may be reduced from 12W to 5W. In other embodiments, the fifth charging power source is greater than the first charging power source. When the controller 430 does not support the wake-up function, the electronic device 110 cannot wake up the components entering the power saving mode through the charging circuit 121 . In a possible embodiment, the user needs to press a power switch to wake up a specific device entering the power saving mode. In this example, when the specific device is woken up, the controller 440 turns on the transmission path PA1 and does not turn on the transmission path PA2 to determine whether the electronic device 110 is a specific device, and instruct the voltage conversion circuit 410 to re-output according to the determination result A third or fourth charging power source.

在其它实施例中,当使用者选择图3B的快充选项312时,控制器440导通传输路径PA1,用以判断电子装置110是否为苹果公司的产品。当电子装置110并非苹果公司的产品时,充电电路121进入第一快充模式。在第一快充模式下,充电电路121输出第二充电电源。当电子装置110为苹果公司的产品时,充电电路121进入第二快充模式。在第二快充模式下,充电电路121输出第三或第四充电电源。由于充电电路121在第一及第二快充模式下的动作原理已揭露如上,故不再赘述。In other embodiments, when the user selects the fast charging option 312 in FIG. 3B , the controller 440 conducts the transmission path PA1 to determine whether the electronic device 110 is a product of Apple. When the electronic device 110 is not a product of Apple, the charging circuit 121 enters the first fast charging mode. In the first fast charging mode, the charging circuit 121 outputs the second charging power source. When the electronic device 110 is a product of Apple, the charging circuit 121 enters the second fast charging mode. In the second fast charging mode, the charging circuit 121 outputs the third or fourth charging power source. Since the operating principles of the charging circuit 121 in the first and second fast charging modes have been disclosed as above, they will not be repeated here.

在其它实施例中,充电电路121更包括一计数器450。计数器450具有一计数值。当使用者选择图2B的时间设定选项214或是图3B的时间设定选项313时,计数器450开始减少或增加计数值。当计数值等于一预设值时,计数器450产生一禁能信号STP。电压转换电路410根据禁能信号STP,停止提供任何电源予电子装置110。在一可能实施例中,该预设值与使用者所输入的充电时间有关。In other embodiments, the charging circuit 121 further includes a counter 450 . The counter 450 has a count value. When the user selects the time setting option 214 of FIG. 2B or the time setting option 313 of FIG. 3B , the counter 450 starts to decrease or increase the count value. When the count value is equal to a preset value, the counter 450 generates a disable signal STP. The voltage conversion circuit 410 stops providing any power to the electronic device 110 according to the disable signal STP. In a possible embodiment, the preset value is related to the charging time input by the user.

由于充电电路121支持多种充电协定,故使用者仅需利用一条连接线便可将电子装置110接上主机板120进行快充,而不需要额外购买特定的充电器。再者,当充电电路121根据快速充电3.0(QC 3.0)协定供电予电子装置110时,电子装置110的电量只需35分钟就可以从0%快速增加至80%。另外,充电电路121也可在30分钟内,将电子装置110的电量快速充电达50%。另外,即使主机板120处于一省电模式(如S3或S4)时,充电电路121仍可持续对电子装置110充电。再者,藉由屏幕130所呈现的充电画面210或310,便于使用者根据自身需求选择合适的充电选项,并增加充电时间选择,作为电源管理机制的双重保护。Since the charging circuit 121 supports a variety of charging protocols, the user can connect the electronic device 110 to the motherboard 120 for fast charging with only one connection cable, and does not need to purchase a specific charger. Furthermore, when the charging circuit 121 supplies power to the electronic device 110 according to the Quick Charge 3.0 (QC 3.0) protocol, the power of the electronic device 110 can be rapidly increased from 0% to 80% in only 35 minutes. In addition, the charging circuit 121 can also rapidly charge the power of the electronic device 110 to 50% within 30 minutes. In addition, even when the motherboard 120 is in a power saving mode (eg, S3 or S4 ), the charging circuit 121 can continue to charge the electronic device 110 . Furthermore, the charging screen 210 or 310 displayed on the screen 130 facilitates the user to select an appropriate charging option according to his own needs, and increase the charging time selection as a dual protection of the power management mechanism.
