R3116x-Y Series 0.8% Low Voltage Detector with Output Delay for Industrial Applications NO.EA-347-170203 OUTLINE The R3116x is a CMOS-based voltage detector IC with high detector threshold accuracy and ultra-low supply current, which can be operated at an extremely low voltage and is used for system reset as an example. This IC consists of a voltage reference unit, a comparator, resistors for detector threshold setting, an output driver, a hysteresis circuit and an output delay circuit. The detector threshold is internally fixed with high accuracy and does not require any adjustment. Two output types, Nch open drain type and CMOS type are available. R3116x is offered in a 5-pin SOT-23-5 package and an ultra-small 4-pin DFN(PLP)1010-4 package which can achieve the smallest possible footprint solution on boards where area is limited. 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.
