●OUTLINE
●The R3111x 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.
●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 single battery.
●Six types of packages, TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, and SON1612-6 are available.
