System Reset

Monolithic IC PST90XX Series

Outline

The function of this low voltage detection type IC is to accurately reset systems after detecting the supply

voltage at the time of switching power on and instantaneous power off in various CPU and other logic

systems. This IC, with its super low consumption current and high precision voltage detection capacity, is

most suited as a voltage check circuit for a number of products which use batteries.

Features

1. High precision voltage detection

VS±±.ꢀ5 maꢁ.

±. Super low current consumption

I^CCH=1.ꢀµA typ. ICCL=1µA typ.

0.7V maꢁ.

3. Low operating threshold voltage

4. Hysteresis voltage is provided as a detect voltage

Vs ꢀ5 typ.

ꢀ. The detect voltage can be selected at your discretion at 0.1 V step within the range of 0.8 to 1.8V by the

following stipulation method.
