If the inserted adapter supports 5V, 9V, 12V, 15V will be output. If the inserted adapter supports 5V, 9V and 12V voltages, 12V is output. If the inserted adapter supports 5V, 9V voltage, 9V will be output. Maximum voltage for other configurations and so on.

Similarly, the external power supply detects that the voltage at pin CC1 or CC2 is pulled low, and when the voltage is within the threshold range, it is determined that there is a chip connected, and a voltage of 5V is output.

Specifically, referring to fig. 4, in this embodiment, the detecting whether the external power supply supports the USB PD protocol includes:

The chip is configured with the voltages of D + and D-, and the external chip has the output corresponding to the voltages. D + outputs 3.3V, D-outputs 0.6V, and the external chip outputs 9V. D + and D-both output 0.6V, and the external chip will output 12V. D + and D-both output 3.3V, and the external chip will output 20V.

and step 238, controlling the chip to send high pulse information to the external power supply.

And 239, finishing communication between the external power supply and the chip AFC protocol if the same high pulse information is detected to be fed back for multiple times.

In this embodiment, the handshake process is the same as QC, and in the QC mode, if the detected actual output after voltage configuration does not match the requested value, the output is left at 5V, which indicates that the external chip does not support QC, and the AFC protocol detection is performed. Sending a high pulse of 2.56ms, namely PING information, if receiving the same PING reply of an external chip, the chip sends the requested voltage and current, if the external chip supports the PING reply, the chip replies the requested voltage and current, and the external chip provides the requested power after repeating the process for 3 times; if the voltage and the current requested by the chip are not supported, the supported power information is enumerated in the replied information, the chip reads the power information, the power supported by the chip is requested according to the self requirement, at the moment, the external chip replies the voltage and the current requested by the chip, and the external chip provides the requested power after repeating the process for 3 times. If the AFC communication process does not respond, the AFC protocol is not supported, and the external chip stays at the 5V output.

And step 240, controlling the external power supply to output a first voltage to the chip according to the communication protocol.
