The function of this low voltage detection type IC is to accurately reset systems after detecting the supply voltage at the time of switching power on and instantaneous power off in various CPU and other logic systems. This IC, with its super low consumption current and high precision voltage detection capacity, is most suited as a voltage check circuit for a number of products which use batteries.
Features
1. High precision voltage detection VS±2.5% max. 2. Super low current consumption ICCH=1.5µA typ. ICCL=1µA typ. 3. Low operating threshold voltage 0.7V max. 4. Hysteresis voltage is provided as a detect voltage Vs 5% typ. 5.
