Title: Electronic switching device
Inventor: KAJITA TETSUYA
IPC: H03K17/945
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To stably secure a power source voltage at the time of conducting an output circuit by comparing the prescribed internal reference voltage of a sensor circuit part with a reference voltage obtained by dropping the power source voltage supplied through a power source line by a fixed voltage so as to keep the power source voltage controlled by an output circuit higher than the internal reference voltage. SOLUTION: In order that a difference between voltages added between the two input terminals of a differential amplifier 17 at the time of conduct- driving the output circuit 8 may be zero, a power source voltage Vcc added between a pair of power source lines La and Lb is feedback-controlled. The voltage Vcc is set to be higher than an internal reference voltage Vref by the forward dropping voltage of a diode based on the voltage Vref of a sensor circuit 6. The voltage Vref is stably generated by using a band gap voltage of a semiconductor and a forward dropping voltage by a diode 12 and a forward dropping voltage by diodes 14 and 15 are regulated by the band gap voltage of a semiconductor to stabilize the voltage Vcc to be feedback-controlled.
