PST591 System Reset Monolithic IC PST591~595 Series

MITSUMI System Reset PST591~595 System Reset Monolithic IC PST591~595 Series Outline These ICs function 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, and has a built-in fixed delay time generating circuit. This series has been represented in the past by PST574/PST575, but these new low reset type system reset ICs expand the delay time series with a counter timer using an analog/digita.

PST591 Features
