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 2.3V/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 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
