R3112x SERIES
LOW
VOLTAGE DETECTOR WITH OUTPUT DELAY
NO. EA-087-070112
OUTLINE
The R3112x Series are
CMOS-based
voltage detector ICs with high detector threshold accuracy and ultra-low supply current, which can be operated at an extremely low
voltage and is used for system reset as an example. Each of these ICs consists of a
voltage reference unit, a comparator, resistor net for detector threshold setting, www.DataSheet4U.com 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. Three types of packages, SOT-23-5, small SC-82AB, and ultra-small SON1612-6 can be selected so that high density mounting on boards is possible.
