R3112Q251A-TR - Brand New RICOH IC Chips
-
Description
The R3112Q251A-TR is a voltage detector IC from the R3112x Series, which is CMOS-based and has high detector threshold accuracy and ultra-low supply current. It can be operated at an extremely low voltage and is typically used for system reset. The IC consists of a voltage reference unit, comparator, resistor net for detector threshold setting, output driver, hysteresis circuit, and 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. There are three types of packages, SOT-23-5, small SC-82AB, and ultra-small SON1612-6, which allow for high-density mounting on boards.
