LOW VOLTAGE DETECTOR
R N5V S S E R IE S
OUTLINE
The RN5VS 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 RN5VS 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. Since the package for these ICs are
SOT-23-5 (Mini-mold) package, high density mounting of the ICs on board is possible.
