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.
