Abstract
An exemplary charging control circuit includes a signal shaping unit, a first switch unit, and a second switch unit. The signal shaping unit receives a control signal, and is capable of reshaping the received control signal to have a time interval transited from a first state to a second state. The first switch unit receives the shaped control signal, and generates a first switching signal. The second switch unit receives the first switching signal, and is capable of being turned on based on the first switching signal for allowing electrical power to be outputted to a battery.
