Abstract
There is provided a voltage detector including a reference voltage generator that generates a constant reference voltage when a power supply voltage is higher than a predetermined threshold voltage, and a detector that, when the power supply voltage exceeds a voltage that is higher than the threshold voltage by a predetermined potential, detects whether the power supply voltage is higher than a defined voltage based on the reference voltage and outputs a detection result.
