Charge controlling semiconductor integrated circuit
First Claim
1. A charge controlling semiconductor integrated:
- circuit comprising;
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, whereina 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.
