1 General Description The series ICs are under voltage detectors with a built in voltage threshold and low power consumption. The are specifically designed to accurately monitor power supplies. The 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.v/.5v/.7v/.9v/.v/.v/4.v/4.5vfor AZ70/5/7/9///4/45 respectively. Built in hysteresis helps to prevent erratic operation in the presence of noise. The series are available in standard packages: TO-9 (bulk or ammo packing) and SOT-89.

In normal steady-state operation when >V DET-, the output will be in a logic high state and V is dependent upon the voltage that the pull-up resistor connected to. Here is some explanations for 's operation.. When the input voltage falls below V DET-, the output will pull down to logic low after a delay time of tphl. In general, at rated output current and, V can be pulled down to a voltage as low as within 0.4V from. (See the Electrical Characteristics section). The voltage level V DET- means the detect voltage. typical). Below minimum operating voltage, the output is undefined.. During power-up, V will remain undefined until rises above V OPR, at which time the output will become valid. V will be in its active low state while V OPR < <V DET+ (V DET+ =V DET- +V HYS ). V DET+ is the release voltage. V HYS means the hysteresis voltage and is the difference voltage between the V DET+ and V DET-. 4. When rises above V DET+, the output will be in its inactive state. After a delay time of tplh, V will be in its logic high state..
