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 CD 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(PL)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.
