System Reset PST70XX
System Reset
Monolithic IC PST70XX Series
Outline
These low reset type 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.
They are ideal for use in battery check circuits for products using batteries, as they have ultra-low current
consumption and a high precision voltage detection function.
Features
1. High precision voltage detection
Vs±2% max.
2. Ultra-low current consumption
ICCH=2A typ. ICCL=3A typ.
3. Low operating limit voltage
0.65V typ.
4. Hysteresis voltage provided in detection voltage
50mV typ.
5. Output current high for ON
30mA typ.
6. Detection voltage can be selected as desired within a range of 1.9V~4.6V
in 0.1V steps, as indicated below.
