Abstract
A charging control circuit includes a charging module, a switch element, a load detecting element, and an adjusting element. According to the power consumption of a chargeable battery of an electronic device, the load detecting element issues a load range signal. According to the load range signal, the adjusting element issues a control voltage to the switch element. According to the control voltage, the switch element is turned on, and the magnitude of a control current from the switch element is correspondingly adjusted. By the charging module, a charging current corresponding to the control current is provided to charge the chargeable battery. Consequently, the magnitude of the charging current is controlled according to the operating situation of the electronic device, and the charging speed is changed.
