Description
The R3131N42EA-TR-F is a low voltage detector IC and part of the R3130N/R3131N Series, designed for use as a system reset generator. The CMOS process provides ultra-low supply current, and the IC can be operated at low voltage. It features a voltage reference, a comparator, resistors for setting voltage detector threshold, an output driver transistor, and an output delay generator.
