VOLTAGE DETECTOR  
AZ70XX  
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

AZ7023/25/27/29/31/33/42/45 respectively. Built in  
hysteresis helps to prevent erratic operation in the pres-  
ence of noise.
