Reset ICs

PST810

Overview

These IC series are a system reset IC built-in delay time circuit.
The IC is a small space on PCB by no external capacitor and small package.
The IC is compatible with a standard Reset "809 series", and can choose a detective voltage at 0.1V steps.

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
