Zusammenfassung:	A switch unit is configured to provide reverse current protection. The switch unit comprises an input terminal, an output terminal, a switch device, an operational amplifier, and a voltage difference circuit. The switch device is coupled between the input terminal and the output terminal. The voltage difference circuit receives the voltage of the output terminal for generating a first signal, where the first signal is greater than the voltage of the output terminal. The operational amplifier is coupled to the input terminal and the first signal for generating a second signal to control the switch device.
