IC for CMOS System Reset PST81XX, 82XX Series

IC for CMOS System Reset

Monolithic IC PST81XX, 82XX Series

Outline

This IC functions in a variety of CPU systems and other logic systems, to detect supply voltage and reset the

system accurately when the power is turned on or interrupted.

To ±1.5% of detection voltage accuracy of the conventional models, a maximum of ±0.5% of super-high

precision is realized, and it is more suitable for battery detection etc. Moreover, the mounting area

significantly contributes to space saving using the SSON package.

Features

±0.5%/2.0~6.0V

±0.8%/0.8~1.9V

2. Ultra-low current consumption 0.25µA typ.

3. Ultra-small package

1.10 1.40mm (SSON-4A)

4. Operating temperature range

-40~+105°C

5. Detecting voltage rank

0.8~6.0V (0.1V step)

6. Output configuration

PST81XX series ······ CMOS output

PST82XX series ······ Open drain output

1. Ultra-high accuracy

Packages
