Multi-stage large-current MOSFET driving circuit with overcurrent protection function

The utility model discloses a multi-stage large-current MOSFET drive circuit with an overcurrent protection function. The multi-stage large-current MOSFET drive circuit comprises a first-stage drive circuit, an overcurrent detection circuit, a second-stage drive circuit and two MOSFETs arranged in parallel, the first-stage driving circuit is used for carrying out overcurrent detection, and a port IN of the first-stage driving circuit receives a PWM signal of a control side; the port CS is connected with the over-current detection circuit to carry out over-current judgment; the port FAULT feeds back the overcurrent signal to a control side and gives an overcurrent alarm; the over-current detection circuit is used for detecting the magnitude of current flowing through the MOSFET and transmitting the current data to the primary driving circuit; the input side of the second-stage driving circuit is connected with the first-stage driving circuit, and the output side of the second-stage driving circuit is connected
