The LMV331IDBVT is a single-channel, general-purpose comparator from Texas Instruments in a SOT-23-5 package. Its open-collector output lets you wire-OR multiple comparators or level-shift to a higher-voltage pull-up rail, but it needs an external resistor to VCC or the logic supply. The 600ns max propagation delay sets the response budget for overcurrent detection, zero-crossing, or window comparators — fast enough for most industrial sensor interfaces but not for high-speed PWM cycle-by-cycle limiting.
Quiescent current maxes at 150µA, keeping the power budget lean in always-on sensor nodes.
