Abstract
A semiconductor switch control circuit includes: a pulse signal generating part configured to generate a pulse signal which becomes a time reference for performing an ON/OFF control of a semiconductor switch; a drive current generating part configured to generate a drive current based on the pulse signal which the pulse signal generating part generates and to supply the drive current to a gate electrode of the semiconductor switch; a current detecting part configured to detect a drain current or a source current of the semiconductor switch; and a drive current control part configured to have a function of controlling a drive current which the drive current generating part generates based on the pulse signal which the pulse signal generating part generates and the current which the current detecting part detects.
