R3112N271A-TR-FA - Brand New RICOH IC Chips
-
Description
The R3112N271A-TR-FA is an IC Chip that belongs to the R3112x series, which are voltage detector ICs. This CMOS-based voltage detector IC has a 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. It consists of a voltage reference unit, a comparator, resistor net for detector threshold setting, an output driver, a hysteresis circuit, and an output delay 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. This IC chip comes in packages like SOT-23-5 (Mini-mold), SC-82AB, SON1612-6.
