R3114x SERIES

0.8% LOW VOLTAGE DETECTOR

OUTLINE

NO.EA-160-090707

The R3114x 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 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 R3114x 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

• Supply Current......................................................................Typ. 0.35μA (-VDET=1.5V, VDD=-VDET+1V)

• Operating Voltage Range......................................................0.5V to 6.0V (Topt=25°C)

• Detector Threshold Range....................................................Stepwise setting with a step of 0.1V in the range

of 0.7V to 5.0V

• Detector Threshold Accuracy................................................±0.8% (-V^DET≥ 1.5V)

• Temperature-Drift Coefficient of Detector Threshold ............Typ. ±30ppm/°C

• Output Types.........................................................................Nch Open Drain "L" and CMOS

• Packages ..............................................................................SOT-23-5, SC-82AB, DFN(PLP)1010-4

APPLICATIONS

• CPU and Logic Circuit Reset

• Battery Checker

• Window Comparator

• Wave Shaping Circuit

• Battery Back-up Circuit

• Power Failure Detector
