Abstract: A circuit device includes a control circuit configured to control a transistor current based on a detected temperature. The detected temperature is a temperature detected by a temperature sensor circuit that detects a temperature of a transistor. The transistor charges a load to which a power supply voltage is supplied. The transistor current is a current flowing through the transistor during charging. The control circuit reduces the transistor current when the detected temperature is higher than a first threshold value, and increases the transistor current when the detected temperature is lower than a second threshold value lower than the first threshold value.
