System Reset PST596~598

System Reset

Monolithic IC PST596~598 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 PST591~595, and these new system reset

ICs offer ultra-small size and low current consumption.

Features

1. Fixed delay time setting by counter timer

2. Low operating limit voltage

3. Hysteresis voltage provided in detection voltage

4. Low current consumption

5. 3 delay time products available

6. Each product has 10 detection voltage ranks.
