Description

The AZ70XX series ICs are under voltage detectors with

a built in voltage threshold and low power consumption.

The AZ70XX are specifically designed to accurately

monitor power supplies.

The AZ70XX use a precision on-chip voltage reference

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 instanta-

neous power off in various CPU systems and other logic

systems. The detect voltage thresholds are 2.3V/2.5V/

2.7V/2.9V/3.1V/3.3V/4.2V/4.5V for AZ7023/25/27/29/

31/33/42/45 respectively. Built in hysteresis helps to pre-

vent erratic operation in the presence of noise.
