Abstract
A charge control device includes: a voltage generator which receives an input voltage and generates an output voltage; a power feeding circuit which supplies the output voltage to a terminal via a voltage supply line; and a control circuit. The control circuit is configured to make the power feeding circuit supply the output voltage when a value of the input voltage or the output voltage is equal to or higher than a first threshold value; electrically cut off the supply of the output voltage by the power feeding circuit when the value of the input voltage or the output voltage is less than the first threshold value; and resume the supply of the output voltage by the power feeding circuit when the value of the input voltage or the output voltage returns to be equal to or higher than the first threshold value.
