R3119N SERIES
36V INPUT VOLTAGE DETECTOR
NO.EA-187-111104
OUTLINE
R3119N Series are CMOS-based 36V input (absolute maximum ratings: 50V) voltage detector with high
detector threshold accuracy and ultra-low supply current. Each of those ICs consists of a voltage reference unit,
a comparator, resistors for detector threshold setting, an output driver and a hysteresis circuit.
There are two types: R3119NxxxA has the C
D
pin for setting the output delay time. R3119NxxxE has the
SENSE pin.
The supply current of IC is only 3.3μA. The detector threshold is fixed in the IC and can be set with a step of
0.1V in the range of 2.3V to 12V. Detector threshold accuracy is 1.5%. The output type is Nch Open drain type.
Since the package for these ICs is small SOT-23-5, 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.

RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS)
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the
recommended operating conditions, even if when they are used over such conditions by momentary
electronic noise or surge. And the semiconductor devices may receive serious damage when they continue
to operate over the recommended operating conditions.
