Abstract
In a gate drive circuit of which an N-channel MOSFET and a P-channel MOSFET are connected in a push-pull manner to amplify an input pulse signal and drive an output element, a temperature correction circuit is connected between gate terminals of the N-channel MOSFET and the P-channel MOSFET. The temperature correction circuit lowers each of gate voltages of the N-channel MOSFET and the P-channel MOSFET as ambient temperature rises.
