According to the present invention, a power supply integrated circuit includes: a sensor voltage supply port which provides a power supply voltage to at least one of the plurality of sensors; a current sensing circuit for sensing a current provided to the sensor voltage supply port and outputting current information; a current change amount sensing circuit for receiving the current information of the current sensing circuit, sensing the change amount of the current, and outputting the current change amount information; a clock circuit outputting time information; and a control logic for determining whether to reset after key on using the current information, the current change amount information, and the time information. Therefore, reset of the IC according to a fault condition is prevented by an inrush current of the sensor.
