LM393LVQPWRQ1

Overview

The LM393LVQPWRQ1 is an automotive-grade, dual low-voltage differential comparator manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features open-drain outputs compatible with CMOS and TTL logic families. The device ensures reliable performance across an extended industrial temperature range from -40°C to +125°C. Key electrical specifications include a propagation delay of 600 ns, a maximum input offset voltage of 2 mV, and a quiescent current of 25 µA per channel. It is housed in a WSON-8 package and meets AEC-Q100 qualification standards for automotive applications.

Feature Summary

• Automotive grade qualification compliant with AEC-Q100 standards
• Ultra-low power consumption suitable for battery-operated systems
• Rail-to-rail input capability for wide common-mode voltage range
• Open-drain output configuration for flexible logic interfacing

Applications

• Automotive sensor signal conditioning
• Battery management system monitoring
• Low-voltage threshold detection circuits
• Industrial process control interfaces

Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification and 'PWR' denotes the WSON-8 package variant. Confirm RoHS compliance status through official manufacturer documentation. Ensure design-in compatibility with target operating temperatures and supply voltages before procurement.

Selection Notes

Select this component when automotive reliability and ultra-low power are critical. Compare against standard LM393 variants if higher supply voltage tolerance or different package options are required. Verify that the open-drain output architecture aligns with the pull-up requirements of the downstream circuitry.

Part Context

This part belongs to the LM393LV family of low-voltage comparators. It shares functional similarities with other Texas Instruments automotive comparators but is distinguished by its specific low-voltage operation and WSON-8 footprint. It serves as a specialized alternative to general-purpose comparators in space-constrained automotive designs.

Replacement Considerations

LM393LVDRQ1: Pin-compatible alternative in SOIC-8 package. LM339LVQDRQ1: Quad-channel version with similar electrical characteristics. Verify package dimensions and thermal performance when substituting.
