LOW VOLTAGE DETECTOR

×5VT SERIES

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)
