    • A first voltage dividing circuit is connected between a power feeding line to feed power from an external power supply to an internal circuit, and a fixed potential to divide a voltage of the power feeding line. A first comparator compares a divided voltage, which has been divided by the first voltage dividing circuit, with a reference voltage, and outputs a signal to turn off a power switch inserted into the power feeding line when the divided voltage exceeds the reference voltage. A first transistor is connected between a first node where the divided voltage, which has been divided by the first voltage dividing circuit, is generated, and the fixed potential, and is turned on when the voltage of the first node exceeds a set voltage.

    • A capacitor array circuit receives a plurality of input signals, generate a single output signal by combining the plurality of input signals, and output the single output signal. A comparator receives the output signal of the capacitor array circuit. A current source, which is disposed between a predetermined fixed voltage source and an output terminal of the switched-capacitor circuit, supplies the current to the output terminal until the output signal of the comparator changes. A plurality of input capacitors in the capacitor array circuit receives a plurality of input signals in parallel with each other. At least one additional regulating capacitor in the capacitor array circuit store the charge to compensate for an offset component caused by the delay in the comparator. The respective output terminals of the plurality of input capacitors and the at least one additional regulating capacitor are combined into one.
