R ×5VT SERIES
LOW VOLTAGE DETECTOR
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.
