Abstract
A gate driving circuit (X) is configured to be capable of driving a driving target transistor (QH) having a gate and a first terminal, and includes: an application terminal to which a negative voltage (VEE) is applied; a driving transistor (MOS) that has a control terminal fed with a control signal (MC) and that is connected between the gate of the driving target transistor and the application terminal; and a bias switcher (B) configured to feed the first terminal of the driving target transistor with either a ground potential (GND) or the negative voltage selectively according to the logic level of the control signal at a timing delayed from the timing at which the control signal switches its logic level.
