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/digital hybrid circuit.
Features
1. Fixed delay time setting by counter timer
Excellent delay time temperature characteristics
2. Low operating limit voltage
3. Hysteresis voltage provided in detection voltage
4. Current consumption for no-load
5. 5 delay time products available
