R3116x Series
0.8% Low Voltage Detector with Output Delay
NO.EA-161-140819
OUTLINE
The R3116x 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, resistors for detector threshold setting, an output driver, a hysteresis circuit and an output delay circuit. The detector threshold is internally fixed with high accuracy and does not require any adjustment. Two output types, Nch open drain type and CMOS type are available. The R3116x series are operable at a lower voltage than that of the R3112x series, and can be driven by a single battery.
