Summary:PURPOSE:To drive an external load with a sufficient load drive current while reducing power consumption. CONSTITUTION:A detection wiring 6 detecting a change in a collector current of an output transistor(TR) 2 driving an external load 1 is provided adjacent to a wiring 5 through which the collector current flows and a control circuit 9 is provided to the device, which controls a bias current of the output TR 2 based on a detection signal by the detection wiring 6.
