Abstract:
According to one embodiment, there is provided an output circuit including a driver transistor and a pre-driver circuit. The driver transistor is connected to an output terminal. The pre-driver circuit is configured to turn ON/OFF the driver transistor. The pre-driver circuit includes a first transistor, a second transistor, a third transistor. The first transistor is configured to control ON speed of the driver transistor. The second transistor is connected in parallel with the first transistor. The second transistor is configured to control ON speed of the driver transistor. The third transistor is connected in parallel with the first transistor and in series with the second transistor. The third transistor is configured to activate or deactivate the second transistor.
