Overview
The LMV7239QM7X/E7002934 is an ultra-low power, low voltage comparator with a 75-ns propagation delay. It operates over a supply voltage range of 2.7 V to 5.5 V and consumes only 65 µA at 5 V. The device features rail-to-rail inputs extending 200 mV beyond the rails for ground and supply sensing. It includes both open-drain and push-pull outputs, eliminating the need for external pull-up resistors in push-pull mode. Qualified for automotive applications under AEC-Q100 standards, it supports temperature grades from -40°C to 125°C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 Grade 1 specifications
- Rail-to-rail input stage allowing extended common-mode voltage sensing
- Integrated push-pull output stage enabling direct drive without external components
Applications
- Portable and battery-powered systems
- Set top boxes
- High-speed differential line receivers
- Window comparators
- Zero-crossing detectors
Procurement Notes
Verify the specific suffix E7002934 against official Texas Instruments documentation to confirm reel packaging details and lot traceability. Ensure the ordering code matches the required SC70 package variant. Confirm that the automotive grade designation aligns with your system's environmental requirements before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring minimal quiescent current alongside fast switching speeds. The dual-output configuration provides flexibility for interfacing with various logic families. Its wide input common-mode range makes it suitable for single-supply applications where signals may approach or slightly exceed the supply rails.
Part Context
This part belongs to the LMV7239-Q1 family of comparators designed for space-constrained and energy-efficient electronic systems. The Q1 designation indicates automotive-grade reliability. The M7 suffix typically denotes the SC70-5 surface-mount package, which offers a compact footprint ideal for modern PCB layouts.
