Overview
VOLTAGE DETECTOR General Description Features Data Sheet AZ70XX 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 instantaneous power off in various CPU systems and other logic systems.
The detect voltage thresholds are 2.

5Vfor AZ7023/25/27/29/31/33/42/45 respectively.
Built in hysteresis helps to prevent erratic operation in the presence of noise.
The AZ70XX series are available in 2 standard packages: TO-92 (bulk or ammo packing) and SOT-89.
· 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 · Extended Temperature Range: -40 to 85oC Applications · Low Battery Voltage Detector · Power Fail Indicator · Processor Reset Generator · Battery Backup Control · Home Electric Appliances TO-92(Bulk Packing) TO-92(Ammo Packing) SOT-89 Oct.
