R3111H291A-T1-FE

R3111E (TO-92) is the discontinued product as of April, 2017. R3111x SERIES LOW VOLTAGE DETECTOR NO.EA-056-170428 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. Seven types of packages, TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, SC-88A and SON1612-6 are available. FEATURES Supply Current ......................................................................
