Title: BATTERY CHARGE CONTROL CIRCUIT, CHARGER AND BATTERY CHARGE CONTROL METHOD
Abstract:
A battery charge control circuit, a charger and a battery charge control method. The charger includes a charge circuit and the battery charge control circuit. The battery charge control circuit includes a first detecting module and a second detecting module. The first detecting module detects whether an external power is input. When the first detecting module detects that an external power is input, the second detecting module detects whether the voltage of the battery exceeds a preset threshold. If the voltage of the battery exceeds the preset threshold, the second detecting module activates charging the battery.
