Patent ID: 8547142

Claim:
A power semiconductor device comprising: an output transistor connected between a power-supply terminal and an output terminal; a gate charge-discharge circuit configured to charge and discharge a first node connected to a gate of said output transistor to ON/OFF control said output transistor; a short switch circuit connected between said first node and said output terminal; and a short control circuit configured to control said short switch circuit, wherein a period when said output transistor is stably in an ON-state after said first node is charged is an ON period, a period when said output transistor is stably in an OFF-state after said first node is discharged is an OFF period, a transition period from said OFF period to said ON period is a turn-ON period, and a transition period from said ON period to said OFF period is a turn-OFF period, wherein in said turn-ON period, said ON period and said turn-OFF period, said short control circuit cuts off electrical connection between said first node and said output terminal through said short switch circuit, and wherein in said OFF period, said short control circuit electrically connects said first node and said output terminal through said short switch circuit.
