An anti-reverse protection circuit (100) includes: an input side (1101, 1102); an output side (1201, 1202); a power supply circuit (130) including a control module (180) and a step-down circuit (190), where the control module is coupled to the input side and the step-down circuit; a unidirectional conduction circuit (140) coupled between the input side and the power supply circuit, and adapted to become closed when the wiring is reverse; and a normally closed switch arranged between the input side and the output side, and coupled to the power supply circuit. When the wiring is correct, the normally closed switch is in a conducting state to allow a circuit between the input side and the output side to be a conducting circuit, and when the external power supply is reversely wired and supplies power to the power supply circuit, the normally closed switch is opened to cut off the circuit between the input side and the output side.Fig. 1
