Reset ICs

IC-PST81

Overview

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 precisionis realized, and it is more suitable for battery detection etc. Moreover, the mounting area signifi cantly contributes to space saving using the SSON package.

Application

・Reset circuits for microcomputers, CPUs and MPUs
・Reset circuits for logic circuits
・Battery voltage check circuits
・Back-up power supply switching circuits
・Level detection circuits

Features

High accuracy detection,
Low current consumption
