LMV7275IDCKRQ1

Overview

The LMV7275IDCKRQ1 is a single-channel, low-voltage analog comparator from Texas Instruments, designed for automotive applications. It operates within a supply voltage range of 1.8 V to 5.5 V and features rail-to-rail input capability. The device utilizes an open-drain output configuration and is housed in a compact SC-70 (SOT-353) package with five pins. Key electrical characteristics include a maximum input offset voltage of 4 mV, a quiescent current of 14 µA, and an output sink current of 34 mA. It functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 standards
• Rail-to-rail input stage for wide common-mode voltage range
• Low power consumption suitable for battery-operated systems
• Open-drain output allows flexible logic level interfacing

Applications

• Automotive sensor signal conditioning
• Battery management system threshold detection
• Industrial process control monitoring
• Over-voltage/under-voltage protection circuits

Procurement Notes

Verify the Q1 suffix confirms AEC-Q100 qualification for automotive use. Confirm the IDCKR suffix corresponds to the SC-70-5 package variant. Ensure the operating temperature range meets specific application requirements of -40°C to +125°C. Cross-reference the manufacturer part number with official Texas Instruments documentation to avoid counterfeit components.

Selection Notes

Select this component when automotive qualification is mandatory. Choose over standard LMV7275 variants if extended temperature performance up to 125°C is required. Consider the open-drain output for compatibility with various pull-up voltages. Evaluate the 14 µA quiescent current against strict power budget constraints in portable or remote automotive modules.

Part Context

This part belongs to the LMV7275 family of low-voltage comparators. The 'Q1' designation indicates it is qualified for automotive applications according to AEC-Q100 standards. It shares functional similarities with other LMV series devices but offers specific reliability enhancements and extended temperature ranges required for automotive environments.

Replacement Considerations

Direct substitutes include LMV7275MG/NOPB for commercial grade or LMV7275MFX for alternative packaging. Verify pinout compatibility and electrical specifications before substitution. Automotive applications require equivalent AEC-Q100 qualified parts.
