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.
