Abstract
A semiconductor circuit component has: an MOS-FET which is a load-control semiconductor switching device with a control terminal; a control signal supply circuit including a charging pump circuit for supplying a control signal to a gate G of the MOS-FET to drive the MOS-FET ; and a drive control circuit for performing drive control only when a switch unit SW externally provided is turned on, so that a power supply voltage is supplied from a battery power supply to the control signal supply circuit to thereby make the control signal supply circuit output the control signal.
