R3114x SERIES
Low Voltage Detector
NO.EA-160-071109
1
OUTLINE
The R3114 series are CMOS-based voltage detector IC 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 and a hysteresis 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.
The R3114 series are operable at a lower voltage than that of the R3111x series, and can be driven by a
single battery.
Three types of packages, SOT-23-5, SC-82AB, and DFN(PLP)1010-4 are available.
FEATURES
Ultra-low Supply Current TYP. 0.35A(at VDD=2.5V, Topt=25°C)
Wide Range of Operating Voltage 0.45V to 6.0V(Topt=25°C)
