Description
The R3112N271C-TR is a voltage detector Integrated Circuit (IC) from the R3112x Series, which belongs to the category of IC Chips. This CMOS-based IC has a high detector threshold accuracy and ultra-low supply current, and is mainly utilized for system reset. It consists of a voltage reference unit, a comparator, resistor net for detector threshold setting, an output driver, a hysteresis circuit, and an output delay circuit. The IC comes with fixed truly accurate internal detector threshold settings, and two output types, Nch open drain type and CMOS type available, which makes it suitable for a wide range of applications. It comes in three options of packages that includes SOT-23-5, small SC-82AB, and ultra-small SON1612-6 for high-density mounting on boards.
