Product Summary

The R3112Q401A-TR is a CMOS-based voltage detector IC with high detector threshold accuracy and ultra-low supply current, which can be operated at an extremely low voltage and is used for system reset as an example. Each of these ICs consists of a voltage reference unit, a comparator, resistor net for detector threshold setting, an output driver, a hysteresis circuit, and an output delay circuit. The detector threshold of R3112Q401A-TR is fixed with high accuracy internally and does not require any adjustment. Two output types, Nch open drain type and CMOS type are available. Three types of packages, SOT-23-5, small SC-82AB, and ultra-small SON1612-6 can be selected so that high density mounting on boards is possible. The applications of the R3112Q401A-TR include CPU and Logic Circuit Reset, Battery Checker, Window Comparator, Wave Shaping Circuit, Battery Back-up Circuit, Power Failure Detector.
