R3119x SERIES 36V INPUT VOLTAGE DETECTOR NO.EA-187-160229 OUTLINE R3119x 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: R3119 xxxxA has the C D pin for setting the output delay time. R3119 xxxxE has the SENSE pin. The supply current of IC is only 3.3A. 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. 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.
