Preliminary Datasheet

VOLTAGE DETECTOR

AZ70XX

General Description

Features

The AZ70XX series ICs are under voltage detectors

with a built in voltage threshold and low power con-

sumption. The AZ70XX are specifically designed to

accurately monitor power supplies.

Low Current Consumption:

I_CCL=300µA Typical

I_CCH=30µA Typical

Low Minimum Operating Voltage for Output

Resetting: 0.8V Typical

Built in Hysteresis Voltage: 50mV Typical

Open Collector Output

The AZ70XX use a precision on-chip voltage refer-

ence and a comparator to measure the input operating

voltage. These ICs can accurately reset the system after

detecting voltage at the time of switching power on and

instantaneous power off in various CPU systems and

Extended Temperature Range: -40 to 85 C

other logic systems. The detect voltage thresholds are Applications

AZ7023/25/27/29/31/33/42/45 respectively. Built in

hysteresis helps to prevent erratic operation in the pres-

ence of noise.
