R3112N161A-TR-FA - Brand New RICOH IC Chips
-
Description
The R3112N161A-TR-FA is a CMOS-based voltage detector integrated circuit (IC) that belongs to the R3112x series. This voltage detector IC is designed with a high detector threshold accuracy and ultra-low supply current, which makes it ideal for system reset. It consists of a voltage reference unit, a comparator, a resistor net for detector threshold setting, an output driver, a hysteresis circuit, and an output delay circuit. The detector threshold is fixed internally with high accuracy and does not require any adjustment. Two output types, Nch open drain type and CMOS type are available. It comes in packages such as SOT-23-5 (Mini-mold), SC-82AB, and SON1612-6.
