Abstract
There is provided a semiconductor device including a power compensation circuit in an apparatus in order to notify of a power supply disconnection failure that a user of the apparatus may not recognize. The power compensation circuit includes a rectifier circuit and a detection circuit. The rectifier circuit is coupled between a first power supply line and a second power supply line. If the voltage of the second power supply line is lower than the voltage of the first power supply line by a predetermined value or more, the rectifier circuit supplies power from the first power supply line to the second power supply line. The detection circuit outputs a detection signal when the current flows through the rectifier circuit.
