System Reset
Monolithic IC PST573
Outline
This IC functions in a variety of CPU systems and other logic systems, to detect power supply voltage and reset the system accurately when power is turned on or interrupted. This ultra-low current consumption high reset type system reset IC was developed using high resistance process and low current circuit design technology.
