5 / 31 page LOW VOLTAGE DETECTOR R ×5VT SERIES 1 OUTLINE The R ×5VT 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 instance, for system reset. Each of these ICs consists of a voltage reference unit, a comparator, resistors for voltage detection, an output driver and a hysteresis circuit. The detector threshold is fixed with high accuracy. The R ×5VT Series are operable by a lower voltage than that for the R×5VL Series, and can be driven by a sin- gle battery. Two output types, Nch open drain type and CMOS type, are available. Three types of packages, TO-92, SOT- 89 (Mini-power Mold), SOT-23-5 (Mini-mold), are available. • Ultra-low Supply Current ............................TYP. 0.8µA (VDD=1.5V) • Broad Operating Voltage Range .................. 0.7V to 10.0V (Topt =25˚C) • Detector Threshold........................................Stepwise setting with a step of 0.1V in the range of 0.9V to 6.0V is possible (refer to Selection Guide). • High Accuracy Detector Threshold..............±2.5% • Low Temperature-Drift Coefficien of Detector Threshold..............TYP. ±100ppm/˚C • Two Output Types.........................................Nch Open Drain and CMOS • Three Types of Packages ..............................TO-92, SOT-89 (Mini-power Mold), SOT-23-5 (Mini-mold) FEATURES APPLICATIONS • CPU & Logic Circuit Reset • Battery Checker • Window Comparator • Wave Shaping Circuit • Battery Back-Up Circuit • Power Failure Detector |
