R3112Q151A-TR-F - Brand New RICOH IC Chips
-
Description
The R3112x Series is a CMOS-based voltage detector IC used for system reset in electronic devices. It has high detector threshold accuracy and ultra-low supply current, making it suitable for operation at extremely low voltage levels. The 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 internally with high accuracy and no adjustment is required. Two output types, Nch open drain type and CMOS type, are available.
