Product details

Micropower comparator for threshold detection

Its defining characteristic is the 1 µA maximum quiescent current, which makes it a fit for battery-powered or always-on threshold monitoring circuits where every microamp counts. The open-drain output lets it interface with higher-voltage logic or drive a pull-up resistor to any rail within the 2 V to 8 V supply range.

80 dB CMRR, 90 dB PSRR – noise rejection in the field

The 80 dB CMRR and 90 dB PSRR are strong for a micropower comparator. In an industrial or automotive environment with supply ripple from a DC-DC converter or common-mode noise on a long sensor cable, these figures mean the threshold stays within the 6 mV input offset budget at 5 V. The part holds its trip point without extra filtering in most panel-level applications.

Frequently asked questions

What is the equivalent of LMC7225IM5X/NOPB?

A functional peer is the TLV9032DDFR, a dual-channel comparator with push-pull output, 100 ns propagation delay, and 1.65 V minimum supply. It is faster and lower-voltage but dual-channel and push-pull – not a pin-for-pin replacement. For a single-channel open-drain micropower comparator, the LMC7225 is the direct part.

What is the pinout of LMC7225IM5X/NOPB?

The SOT-23-5 pinout is standard: pin 1 is OUT, pin 2 is V-, pin 3 is IN+, pin 4 is IN-, pin 5 is V+. The open-drain output requires an external pull-up resistor to the desired logic rail.
