R3112N171A-TR-F - Brand New RICOH IC Chips
-
Description
The R3112x Series are CMOS-based voltage detector ICs with high detector threshold accuracy and ultra-low supply current. These ICs can be operated at an extremely low voltage and are commonly used for system reset. Each IC 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. There are two output types available: Nch open drain type and CMOS type.
