Data Sheet VOLTAGE DETECTOR AZ70XX General Description Features The AZ70XX series ICs are under voltage detectors Low Current Consumption: with a built in voltage threshold and low power con- I =300A Typical CCL sumption. The AZ70XX are specifically designed to I =30A Typical CCH accurately monitor power supplies. Low Minimum Operating Voltage for Output Resetting: 0.8V Typical The AZ70XX use a precision on-chip voltage refer- Built in Hysteresis Voltage: 50mV Typical ence and a comparator to measure the input operating Open Collector Output voltage. These ICs can accurately reset the system after o Extended Temperature Range: -40 to 85 C 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 Applications 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.
