1 / 16 page LOW VOLTAGE DETECTOR WITH OUTPUT DELAY R3112xxx1A/C Series 2001. Apr. 4 Rev. 1.10 - 1 - s OUTLINE The R3112 Series are voltage detector ICs with high detector threshold accuracy and ultra-low supply current by CMOS process, 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, 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. Two types of packages, SOT-23-5 and ultra small SC-82AB can be selected so that high density mounting on boards is possible. s FEATURES qBuilt-in Output Delay Circuit• • • • • • • • • • •TYP. 100ms with an external capacitor: 0.022 µF qUltra-low Supply Current• • • • • • • • • • •TYP. 1.0µA (VDD=3.5V) qWide Range of Operating Voltage • • • • • •0.7 ∼6.0V(Topt=25°C) qDetector Threshold • • • • • • • • •Stepwise setting with a step of 0.1V in the range of 0.9V to 5.0V is possible. qHigh Accuracy Detector Threshold • • • • • • • ±2.0% qLow Temperature-Drift Coefficient of Detector Threshold• • • • • • • • • TYP. ±100ppm/ °C qTwo Output Types• • • • • • • • • • • • • • • • • • • Nch Open Drain and CMOS qTwo Types of Packages • • • • • • • • • • SOT-23-5 (Mini-mold), SC-82AB s s s s APPLICATIONS • CPU and Logic Circuit Reset • Battery Checker • Window Comparator • Wave Shaping Circuit • Battery Back-up Circuit • Power Failure Detector s BLOCK DIAGRAMS R3112XXX1A R3112XXX1C VDD Vref OUT GND CD + - RD Vref VDD OUT GND CD + -- RD |
