Abstract
An integrated circuit device, for a power supply that is connected to an AC power source via an input circuit having a capacitor, is able to reliably discharge the capacitor when the AC power source is interrupted. The integrated circuit device includes a first discharge circuit that operates in response to an internal supply voltage and discharges the capacitor via a first switch element that is turned on when the input voltage provided via the input circuit falls below a set voltage, and a second discharge circuit having a second switch element that is turned off when receiving the internal supply voltage but is turned on in response to the input voltage when the supply of internal supply voltage is interrupted.
