APR3001/2/3

MicroPower Microprocessor Reset Circuit

Features

General Description

•

1.2V to 6V Input Voltage Range

The APR3001/2/3 are designed to monitor voltage

supplies in µP and digital systems. The quiescent

current is extremely low, typically 1.5 µA, making it

Low Quiescent Current : less Than 1.5 µA

High accuracy detection threshold : ±1.5%

Fixed trimmed reset thresholds for 1.5V, 1.75V, ideal for portable battery operated equipment. The

2.32V, 2.63V, 2.93V, 3.08V, 3.9V, 4.38V.

Reset Timeout Period 250ms

APR3001/2/3 operate by monitoring the system

power supply voltage. When the input voltage drops

below a fixed threshold, the device asserts a reset

signal for a fixed time period after Vcc rises above

the fixed threshold. The APR3001/2/3 series is avail-

able with three output stage versions : APR3001

push-pull active low output, APR3002 push-pull ac-

tive high output and APR3003 open drain active low

output. They are also designed to reject fast line tran-

sient glitches on Vcc. The APR3001/2/3 are come in

a miniature SOT-23, SOT-23-5, SOT-89 packages.
