Abstract
A protection function of an electronic device is realized with a lower cost. A load drive circuitincludes: transistors Qa and Qb for protection of an N-channel type connected between a power source terminal Pand a power source end Pfor driving; an inverter circuitthat drives a load based on an input drive control signal Sd, the inverter circuitbeing disposed between the power source end Pfor driving and a ground potential; and a booster unitincluding a capacitor Chaving one terminal connected to an output end of the inverter circuit, the booster unitgenerating, across another terminal of the capacitor C, a voltage exceeding a power source voltage Vdc, and applying the voltage to control electrodes of the transistors Qa and Qb for protection.
