TLV7042QDGKRQ1

Comparators Overview

The TLV7042QDGKRQ1 is an automotive-grade, dual-channel analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 1.6 V to 8 V and features rail-to-rail input and output capabilities. Key electrical parameters include a maximum propagation delay of 3 µs, an input offset voltage of 8 mV, and an input bias current of 2 pA. The device draws a quiescent current of 750 nA per channel and supports a maximum operating temperature of +125°C. It is housed in an 8-pin VSSOP package.

Comparators Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Rail-to-rail input and output functionality enables operation across the full supply voltage range.
• Low-power architecture provides ultra-low quiescent current consumption for battery-sensitive applications.

Comparators Applications

• Battery management systems in electric vehicles
• Temperature sensing circuits
• Current limit detection

Comparators Procurement Notes

Verify the complete part number including the suffix 'DGKRQ1' to ensure correct packaging and automotive grade specification. Confirm that the procurement source provides valid traceability documentation required for automotive supply chains. Ensure compatibility with RoHS directives and check for any specific handling requirements associated with the VSSOP-8 package during assembly.

Comparators Selection Notes

Select this component when dual-channel comparison is required in space-constrained automotive designs. The low input bias current makes it suitable for high-impedance sensor interfaces. Compare against single-channel variants if only one comparator is needed, or higher-speed comparators if propagation delay constraints are tighter than 3 µs.

Comparators Part Context

This device belongs to the TLV704x-Q1 family of rail-to-rail, low-power comparators from Texas Instruments. It shares functional similarities with the TLV7041QDCKRQ1 but offers two channels instead of one. The Q1 suffix denotes automotive qualification, distinguishing it from commercial-grade counterparts like the standard TLV7042.

Comparators Replacement Considerations

The TLV7041QDCKRQ1 serves as a single-channel alternative within the same family. For pin-compatible replacements, verify specific parameter matches such as propagation delay and supply voltage range before substitution.
