PST852A
Overview
This is a reset IC with an independent voltage detection monitor terminal VS and VDD terminal.
The IC power supply is separate and so, even if the monitor voltage VS is low, the output does not become unstable at the operation limit like conventional reset ICs. Instead it maintains low-level operation.
This IC is particularly suitable for low-voltage (1V type) power monitoring. It has an accuracy of ±1.5% and an ultralow current consumption of 0.35 µA typ. and otherwise offers characteristics resembling those of conventional IC reset ICs.
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
