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
ICCH=7.5A typ. ICCL=400A typ.
2. Low operating limit voltage
0.65V typ.
3. Output current high for ON
30mA typ.
4. Hysteresis voltage provided in detection voltage
50mV typ.
5. Delay time can set over a wide range using
external capacitor and resistor.
10S~10S
6. 10 ranks of detection voltage
PST575
C : 4.5V typ.
H : 3.1V typ.
D : 4.2V typ.
I : 2.9V typ.
E : 3.9V typ.
J : 2.7V typ.
F : 3.6V typ.
K : 2.5V typ.
G : 3.3V typ.
L : 2.3V typ.
