R3111Q381A-TR-FA - Brand New RICOH IC Chips
-
Description
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 are used, for example, for system reset. 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 are available: Nch open drain “L” type, Nch open drain “H” type, and CMOS type. The R3111x Series are operable at a lower voltage than the Rx5VL series and can be driven by a single battery.
Six types of packages are available: TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, and SON1612-6.Specifications and features
