36V Input Voltage Detector with Delay Function for Automotive Applications
The R3119N is a CMOS-based 36V input (absolute maximum ratings: 50V) voltage detector (VD) provided with high detector threshold accuracy and ultra-low supply current. Internally, the R3119N consists of a voltage reference unit, a hysteresis comparator, a resistor net for setting output voltage and an output driver transistor.
The R3119NxxxA is equipped with a CD pin and the R3119NxxxE is equipped with a SENSE pin.
The supply current of IC is only 3.3 μA. The detector threshold range is 2.3V to 12V, and the detector threshold accuracy is 1.5%. The output type is Nch. open drain "L" output.
The R3119N is available in a 5-pin SOT-23-5 package. Use of this package achieves high-density mounting on boards.
