Abstract
According to one embodiment, a gate control circuit includes a controller, a delay circuit, a power circuit, a boosting circuit, a first transistor, and a control circuit. The controller outputs first and second control signals based on a control signal from outside. The delay circuit delays the first control signal. The power circuit is capable of controlling a power supply voltage to be output based on the delayed first control signal. The boosting circuit is capable of boosting and outputting an input voltage. The first transistor has one end connected to an output node of the boosting circuit, and the other end grounded. The control circuit is capable of controlling a gate voltage of the first transistor based on the second control signal.
