Abstract

See full text

A semiconductor device for driving an inductive load. The semiconductor device includes an output-stage switch connected to the inductive load for operating the inductive load; a voltage detection circuit configured to output a detection signal responsive to an overvoltage being higher than or equal to a clamp voltage; a drive circuit configured to apply a drive signal having a first threshold voltage to a gate of the output-stage switch, responsive to the overvoltage being lower than the clamp voltage, to turn on the output-stage switch; and a voltage application circuit configured to apply a voltage signal having a second threshold voltage higher than the first threshold voltage to the gate of the output-stage switch, responsive to the overvoltage being higher than or equal to the clamp voltage and upon receiving the detection signal from the voltage detection circuit, to turn on the output-stage switch.
