Protection circuit and electronic equipment

The utility model is suitable for the technical field of electronic circuits, and provides a protection circuit and electronic equipment, and the protection circuit is used for protecting a target circuit. The protection circuit comprises a sampling circuit, a comparison circuit and a detection circuit. The sampling circuit is used for sampling a target parameter of a target circuit and outputting a sampling value; the comparison circuit is connected with the sampling circuit and is used for outputting a turn-off signal when the sampling value is greater than or equal to a first reference value; the turn-off signal is used for controlling the target circuit to be turned off; the first end of the detection circuit is connected between the sampling circuit and the comparison circuit, and the second end of the detection circuit is connected with a target circuit; the detection circuit is used for carrying out fault detection on at least one of the sampling circuit and the comparison circuit and outputting a faul
