single battery.
FEATURES
APPLICATIONS
LOW VOLTAGE DETECTOR
The R3111x series are CMOS-based voltage detector ICs with high detector threshold accuracy and ultra-low
Each of these ICs consists of a voltage reference unit, a comparator, resistors for detector threshold setting,
Three output types, Nch open drain “L” type, Nch open drain “H” type and CMOS type are available.
The R3111x Series are operable at a lower voltage than that for the Rx5VL series, and can be driven by a
Six types of packages, TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, and SON1612-6 are available.
