In the constant voltage charging stage, the charging current will gradually decrease. When the charging current decreases to the value set by the external resistor, Charging is complete. The constant current charging current is set by the current detection resistor RCS connected between the CSP pin and the BAT pin. In the constant voltage charging mode, the battery voltage is 12.6V, and the accuracy is 1%.
