Product details

The Texas Instruments LMV7271MGX is a single-element, general-purpose comparator in a 5-pin SC-70-5 package. It runs on a 1.8 V to 5.5 V single supply (or ±0.9 V to ±2.75 V dual).

The 14 µA quiescent current is the headline number for battery-powered designs — it keeps the comparator alive in a threshold-monitoring role without draining the cell. The 2.1 µs propagation delay is fast enough for most power-good and over-current trip circuits.

The SC-70-5 package is small enough to fit on a crowded sensor PCB.

Frequently asked questions

What is the closest functional equivalent for LMV7271MGX from other brands?

The TLV9032DDFR is a dual comparator with similar rail-to-rail push-pull output but faster propagation delay (100 ns) and wider temperature range (-40°C to 125°C). It is not a pin-for-pin replacement — the TLV9032 is a dual in a different package — but it covers the same functional space if you need two channels or higher speed.
