In some examples, a hysteresis comparator includes a series resistor portion including a plurality of resistors for dividing a power supply voltage, the series resistor portion generating a first midpoint voltage and a second midpoint voltage higher than the first midpoint voltage, a first comparator configured to compare the first midpoint voltage and a reference voltage, a second comparator configured to compare the second midpoint voltage and the reference voltage, and a flip-flop having a clock terminal to which an output signal of the first comparator is applied and a reset terminal to which an output signal of the second comparator is applied. In some examples, a hysteresis comparator further includes an OR gate to which output signals of the first comparator and the second comparator are applied, and an AND gate to which output signals of the first comparator and the second comparator are applied.
