System Reset
Monolithic IC 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
