1 / 2 page  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.
