Outline

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. The detect voltage can be selected at your discretion at 0.1 V step within the range of 0.8 to 1.8V by the following stipulation method.

Applications

1. Reset circuits for microcomputers, CPUs and MPUs

2. Reset circuits for logic circuits

3. Battery voltage check circuits

4. Back-up power supply switching circuits

5. Level detection circuits
