A protecting circuit connected between a power supply and a load includes an interface unit, a switching unit, a protection module, a locking unit, and a trigger unit. The interface unit is used for connecting to the load. The switching unit turns on to establish a connection between the power supply and the load when the interface connects to the load and turns off to cut off the connection. The protection module generates a protecting signal when the output of the power supply is in an abnormal state, and the locking unit controls the trigger unit to generate a control signal. The switching unit cuts off the connection in response to the control signal. When the output of the power supply resumes to a normal state, the switching unit automatically resumes the connection by reconnecting the interface with the load. |
