Abstract
An embodiment includes a controller and a driver. The controller controls to drive a semiconductor element having a first gate electrode and a second gate electrode base on a control signal. The driver outputs a first driving signal to the first gate electrode and a second driving signal to the second gate electrode. The first driving signal drives the first gate electrode at ON or OFF timing of the control signal. The second driving signal drives the second gate electrode a timing earlier than the OFF timing of the control signal. The driver switches output impedances corresponding to the switching speed of the semiconductor element.
