DRIVE CIRCUIT

A gate driver IC includes a plurality of switching elements that drives an IGBT; a comparator that outputs an alarm signal in a case where a potential of a shunt resistor connected between an emitter terminal of the IGBT and a ground is equal to or higher than a Vth1; a delay circuit that outputs a trigger signal after the comparator starts outputting the alarm signal; and a controller that controls on and off of the plurality of switching elements. The switching elements of an upper arm include PMOSs connected to a same voltage source. The switching elements of a lower arm include NMOSs. The controller turns off the PMOS when the alarm signal is output, and turns on the NMOS when the trigger signal is output.
