R3119x-Y Series
36 V Input Voltage Detector with Delay Function for Industrial Applications
NO.EA-378-160613
OUTLINE
The R3119x is a CMOS-based 36 V input (absolute maximum ratings: 50 V) voltage detector (VD) provided
with high detector threshold accuracy and ultra-low supply current. Internally, the R3119x consists of a voltage
reference unit, a hysteresis comparator, a resistor net for setting output voltage and an output driver transistor.
The R3119xxxxA is equipped with a C
D
pin and the R3119xxxxE is equipped with a SENSE pin.
The supply current of IC is only 3.3 µA. The detector threshold range is 2.3 V to 12 V, and the detector threshold
accuracy is 1.5%. The output type is Nch. open drain “L” output.
The R3119x is offered in a small-size 6-pin DFN(PLP)1820-6 package in addition to a 5-pin SOT-23-5 package.
This is a high-reliability semiconductor device for industrial applications (-Y) that has passed both the screening
at high temperature and the reliability test with extended hours. This line of products operate in a wide temperature
range from low temperature to high temperature to support harsh environment applications.

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

RECOMMENDED OPERATING CONDITIONS
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.
