Abstract
A power semiconductor device has: an output transistor connected between a power-supply terminal and an output terminal; a gate charge-discharge circuit configured to charge/discharge a first node connected to a gate of the output transistor to ON/OFF control the output transistor; a short switch circuit connected between the first node and the output terminal; and a short control circuit configured to control the short switch circuit. In the turn-ON period, the ON period and the turn-OFF period, the short control circuit cuts off electrical connection between the first node and the output terminal through the short switch circuit. In the OFF period, the short control circuit electrically connects the first node and the output terminal through the short switch circuit.
