AZ70XX
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.
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
other logic systems. The detect voltage thresholds are
2.3V/2.5V/2.7V/2.9V/3.1V/3.3V/4.2V/4.5Vfor
AZ7023/25/27/29/31/33/42/45 respectively. Built in
hysteresis helps to prevent erratic operation in the pres-
ence of noise.
The AZ70XX series are available in 2 standard pack-
ages: TO-92 (bulk or ammo packing) and SOT-89.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to
the device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under"Recommended Operating Conditions" is not implied. Exposure to "Absolute Maxi-
mum Ratings" for extended periods may affect device reliability.
