OUTLINE

The R3112 Series are voltage detector ICs with high detector threshold accuracy and ultra-low supply current by CMOS

Two types of packages, SOT-23-5 and ultra small SC-82AB can be selected so that high density mounting on boards is

Each of these ICs consists of a voltage reference unit, a comparator, resistor net for detector threshold setting, an
