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:
ICCL=300µA Typical
ICCH=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
