Abstract
According to one embodiment, a drive control circuit includes a first transistor that supplies a current to a gate of an output transistor in response to a drive signal, a second transistor that supplies a current to a capacitor in response to the drive signal, a comparison circuit that compares a gate voltage of the output transistor and a voltage of the capacitor, a control signal generation circuit that generates a control signal in response to an output signal of the comparison circuit and the drive signal, and a third transistor that supplies a current to a gate of the output transistor in response to the control signal.
