LMV7239M5/NOPB

Overview

The LMV7239M5/NOPB is a single-channel, ultra-low power, low-voltage comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 5.5V and features rail-to-rail input capability, allowing the common-mode voltage to extend 200mV beyond both ground and the positive supply rail. The device provides a propagation delay of 75ns while consuming only 65µA of supply current at 5V. It utilizes a push-pull output stage, eliminating the need for external pull-up resistors. The component is housed in a compact 5-pin SOT-23 package.

Feature Summary

• Rail-to-rail input stage with extended common-mode voltage range extending 200mV below ground and above the positive supply.
• Push-pull output architecture that functions without requiring external pull-up resistors.
• Ultra-low power consumption of 65µA at 5V supply with 75ns propagation delay.

Applications

• Battery-powered systems requiring minimal quiescent current
• Ground-sensing applications utilizing the extended negative input range
• Power-supply monitoring circuits

Procurement Notes

Verify the specific suffix 'M5' corresponds to the 5-pin SOT-23 tape-and-reel packaging configuration. Confirm the 'NOPB' designation indicates lead-free and RoHS compliance status as per the manufacturer's latest documentation. Ensure the operating temperature range aligns with system requirements, typically up to 85°C for this package variant.

Selection Notes

Select this component when a small footprint and low static current are critical constraints. The push-pull output distinguishes it from open-drain variants like the LMV7235, simplifying circuit design by removing the need for external load resistors. Verify that the 75ns propagation delay meets the timing specifications of the target application.

Part Context

This part belongs to the LMV723x family of comparators designed for portable electronics. It shares core electrical characteristics with the LMV7235 but differs in output topology. The family targets applications where space and battery life are primary design drivers, offering high performance in a miniature surface-mount package.

Replacement Considerations

The LMV7235M5/NOPB serves as a functional substitute if an open-drain output is acceptable or preferred. Other members of the LMV723x series may offer different propagation delays or output configurations.
