VOLTAGE DETECTOR

WITH OUTPUT DELAY

RN5VD SERIES

1

OUTLINE

The RN5VD Series are voltage detector ICs with output delay functions and high detector threshold

accuracy and ultra-low supply current by CMOS process, which can be operated at an extremely low volt-

age 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, a hysteresis circuit and an output delay generator. The detector threshold is fixed with high

accuracy in the IC and requires no adjustment.

The RN5VD Series are operable by a lower voltage than that for the R

by a single 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.
