1 / 12 page  VOLTAGE DETECTOR AZ70XX AZ70XX Preliminary Datasheet 1 Jul. 2005 Rev. 1. 3 BCD Semiconductor Manufacturing Limited General Description 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 and SOT-89-3. Features · 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 SOT-89-3 Figure 1.
