Data Sheet VOLTAGE DETECTOR AZ70XX General Description Features 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. · · · Applications · · · · · The AZ70XX series are available in 2 standard packages: TO-92 (bulk or ammo packing) and SOT-89.

Below minimum operating voltage, the output is undefined. Figure 12 is a typical timing waveform for AZ70XX. In normal steady-state operation when VCC>VDET-, the output will be in a logic high state and VOUT is dependent upon the voltage that the pull-up resistor connected to. 3. During power-up, VOUT will remain undefined until VCC rises above VOPR, at which time the output will become valid. VOUT will be in its active low state while VOPR
