RN5VD SERIES
LOW VOLTAGE DETECTOR WITH OUTPUT DELAY
NO. EA-027-160309
OUTLINE
The RN5VD Series are CMOS-based voltage detector ICs with high detector threshold accuracy and ultra-low
supply current, which can be operated at an extremely low voltage and is used for system reset as an example.
Each of these ICs consists of a voltage reference unit, a comparator, resistor net for detector threshold setting,
an output driver, a hysteresis circuit, and an output delay circuit. The detector threshold is fixed with high accuracy
internally and does not require any adjustment. Two output types, Nch open drain type and CMOS type are
available.
Since the package for these ICs is SOT-23-5 package, high density mounting of the ICs on board is possible.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system using the device
in the field. The functional operation at or over these absolute maximum ratings is not assured.
