Monolithic IC PST575

System Reset PST575

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 low

reset type system reset IC has a built-in delay time generating circuit that can set the time by an external

capacitor and resistor. It is ideal for use in multi-CPU systems because a fast-rising output waveform can be

obtained.

Features

1. Ultra-low current consumption

2. Low operating limit voltage

3. Output current high for ON

4. Hysteresis voltage provided in detection voltage

5. Delay time can set over a wide range using

external capacitor and resistor.

6. 10 ranks of detection voltage
