Abstract
Disclosed is a charge controlling semiconductor integrated circuit including: an electric current controlling transistor connected between a voltage input terminal and an output terminal to control an electric current which flows from the voltage input terminal to the output terminal; a power source monitoring circuit to detect status of input voltage of the voltage input terminal; and a transistor element connected between the voltage input terminal and a ground potential point, wherein a bypass capacitor is connected to the voltage input terminal; and the transistor element is turned on and the bypass capacitor discharges when the power source monitoring circuit detects the input voltage of the voltage input terminal is cut off.
