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 (V
DD
=1.5V)
Broad Operating Voltage Range..................0.7V to 10.0V (Topt =25C)
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%
