APR3011/2/3

MicroPower Microprocessor Reset Circuit

Features

General Description

The APR3011/2/3 are designed to monitor voltage sup-

plies in mP and digital systems. The quiescent current is

extremely low, typically 1.5µA, making it ideal for portable

battery operated equipment. The APR3011/2/3 operate

by monitoring the system power supply voltage. When

the input voltage drops below a fixed threshold, the de-

vice asserts a reset signal for a fixed time period after Vcc

rises above the fixed threshold. The APR3011/2/3 series

are available with three output stage versions: APR3011

push-pull active low output, APR3012 push-pull active

high output, and APR3013 open drain active low output.

They are also designed to reject fast line transient glitches

on V_CC. The APR3011/2/3 come in a miniature SOT-23-3,

SOT-23-5, and SOT-89 packages.
