Power-on signal generating circuit operating with low-dissipation current

A P-channel field effect transistor (FET) T5 is connected between a constant current circuit constituted by first and second P-channel FETs T1 and T2 and first and second N-channel FETs T6 and T7, and a resistor, and a voltage detecting circuit. A gate of the FET T5 is connected to an output of the...

Summary:A P-channel field effect transistor (FET) T5 is connected between a constant current circuit constituted by first and second P-channel FETs T1 and T2 and first and second N-channel FETs T6 and T7, and a resistor, and a voltage detecting circuit. A gate of the FET T5 is connected to an output of the voltage detecting circuit, a drain of which is connected to the gates of the FETs T6 and T7, and a source of which is connected to a power supply. The FET T5 operates so as to quickly start the constant current circuit when powered.
