Abstract
A power saving system of a battery charger is provided. A control terminal of a first transistor receives a wake-up signal. A counter is connected to a first terminal of the first transistor. The counter determines whether or not a working period of the wake-up signal from the first transistor is larger than a time threshold to output a counting signal. When the counting signal indicates that the working period of the wake-up signal is not larger than the time threshold, the counter and electronic components of an electronic device are turned off, thereby saving power of a battery. When the counting signal indicates that the working period of the wake-up signal is larger than the time threshold, the electronic device is switched from a power saving mode to a normal operation mode. In the normal operation mode, the battery can supply power to the electronic device.
