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=2µA typ. ICCL=3µA 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.
