Abstract

In one semiconductor chip, driving transistors, a current sensor, and a temperature sensor for sensing a temperature of a driver area are arranged in a driver area, and a current sensing circuit, an analog-digital converter, and a temperature sensor for sensing a peripheral circuit area are arranged in a peripheral circuit area. A correction circuit unit corrects a digital sensed voltage from the analog-digital converter based on a sensing result of the temperature sensor of the driver area and a sensed result of the temperature sensor of the peripheral circuit area.
