s OUTLINE

The R3112 Series are voltage detector ICs with high detector threshold accuracy and ultra-low

supply current by CMOS process, 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 is fixed with high accuracy internally and does not require any adjustment. Two output types,

Nch open drain type and CMOS type are available.

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

mounting on boards is possible.
