LMV331TP-TR

The LMV331TP-TR is 3PEAK's single general-purpose comparator in SOT-23-5 tape-and-reel form, specified by 3PEAK datasheet PM009 for the LMV331TP/LMV393TP family. It runs from 1.8 V to 5.5 V - a lower starting voltage than most LMV331-class parts - with rail-to-rail inputs, an open-drain output, typical input offset of plus/minus 0.6 mV and quiescent current of 40 uA typical per comparator. Built-in hysteresis of about 6 mV keeps slow sensor edges from chattering, and propagation delay is 120 ns high-to-low and 250 ns low-to-high at 100 mV overdrive, fast enough for battery supervision, window detection and level translation in portable products. Brand clarity matters on this page: this is the 3PEAK device. MSKSEMI sells a near-identical base name, LMV331TP-MS, under its own datasheet with a 2.1 V minimum supply; the two parts share a functional class and package style but are different manufacturers' order codes with different guaranteed limits. Selection advice: quote the full LMV331TP-TR code including the -TR suffix, design the pull-up for the open-drain output explicitly, and if your rail must work below 2.1 V, this 3PEAK variant's 1.8 V floor is the deciding specification.
