LMV331QDBVRSV

Overview

The LMV331QDBVRQ1 is a single-channel, low-voltage analog comparator designed for automotive applications. It operates within a supply voltage range of 2.7 V to 5.5 V and features an open-collector output. The device supports rail-to-rail input common-mode voltage, including ground. Key electrical specifications include a typical propagation delay of 600 ns at 5 V, a maximum input offset voltage of 7 mV, and a typical supply current of 60 μA. It is housed in a SOT-23-5 (DBV) package and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Qualified for automotive applications under AEC-Q100 standards
• Low supply current consumption suitable for portable designs
• Open-collector output configuration for flexible interfacing
• Input common-mode voltage range extends to ground

Applications

• Automotive sensor signal conditioning
• Portable consumer electronics power management
• General-purpose threshold detection circuits

Procurement Notes

Verify the specific ordering suffix against the Package Option Addendum to confirm the exact tape-and-reel quantity and lead finish. Ensure the component status is listed as Active Production before finalizing procurement plans. Confirm that the RoHS compliance and material type align with project requirements. Cross-reference the part marking code to validate the manufacturing site if traceability is required.

Selection Notes

Select this component when automotive qualification and low-voltage operation are mandatory. The LMV331QDBVRQ1 serves as the single-comparator variant within the LMV331-Q1 family. Consider the open-collector output requirement for pull-up resistor integration. Evaluate the 60 μA typical supply current against system power budgets. Verify that the SOT-23-5 package dimensions fit the available PCB real estate constraints.

Part Context

This device belongs to the LMV331-Q1 series, which provides low-voltage alternatives to legacy comparators like the LM331. It is specifically engineered for cost-effective solutions in portable consumer products requiring space-saving packages. The Q1 designation indicates adherence to automotive reliability standards, distinguishing it from standard catalog versions.

Replacement Considerations

LMV331QDBVRQ1 is the direct automotive-grade replacement for the standard LMV331QDBVRQ1.A or .B variants. Catalog versions such as LMV331 may lack the specific automotive qualification but share identical pinouts and electrical characteristics.
