R3114x SERIES
0.8% LOW VOLTAGE DETECTOR
NO.EA-160-120423
OUTLINE The R3114x series are CMOS-based voltage detector ICs 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, resistors for detector threshold setting, an output driver and a hysteresis 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. The R3114x series are operable at a lower voltage than that of the R3111x series, and can be driven by a single battery. Three types of packages, SOT-23-5, SC-82AB, and DFN(PLP)1010-4 are available.
