Beschreibung
Zusammenfassung:	The invention relates to the technical field of integrated circuit design, in particular to a short-circuit protection circuit, which comprises a first switching tube, a second switching tube, a third switching tube and a fourth switching tube, the driving end of the driving module is connected with the grid of the first switching tube; the detection end of the short-circuit detection module is connected with the input end of the short-circuit protection circuit; the discharge end of the short-circuit detection module is connected with the driving end of the driving module; the short circuit detection module obtains the input current of the input end, and when the input current exceeds a threshold value, the short circuit detection module pulls down the level of the driving end through the discharge end so as to close the first switching tube. The beneficial effects are that the input current of the input end of the short-circuit protection circuit is obtained through arranging the short-circuit detection mod
