R3112D321A - Brand New RICOH IC Chips
-
Description
The R3112D321A is a CMOS-based voltage detector IC, which is a part of the R3112x Series. These voltage detector ICs have a high detector threshold accuracy and ultra-low supply current. The ICs can operate at an extremely low voltage and are used for system reset in various applications. The R3112D321A 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. The ICs are available in three types of packages, SOT-23-5, small SC-82AB, and ultra-small SON1612-6, which makes high density mounting on boards possible.
