An electronic device receiving a voltage from a power supply comprises a load, a control module, a switching module, and a protection module. The control module generates a first control signal. The protection module transmits the first control signal to the switching module. The switching module establishes an electrical connection between the power supply and the load in response to the first control signal. The load is powered by the power supply when the electrical connection between the power supply and the load is established. The protection module connected between the control module and the switching module prevents a reverse current or a reverse voltage supplied by the power supply from being transmitted to the control module.
