TLV9024QDRQ1

Comparators Overview

The TLV9024QDRQ1 is an automotive-grade quad-channel analog comparator from Texas Instruments, designed for high-precision applications in harsh environments. It operates within a supply voltage range of 1.65 V to 5.5 V and features rail-to-rail input capability that exceeds the supply rails. The device provides an open-drain output stage, allowing flexible pull-up configurations. Key electrical specifications include a typical propagation delay of 100 ns, a low quiescent current of 16 μA per channel, and a precision input offset voltage of 300 μV. It is qualified under AEC-Q100 standards with a temperature grade of 1, supporting operation from -40°C to +125°C.

Comparators Feature Summary

• Features Power-On Reset (POR) logic to ensure outputs remain in a known state during system power-up and power-down sequences.
• Includes fault-tolerant inputs capable of withstanding voltages up to 6 V without damage or output phase inversion.
• Provides open-drain output configuration suitable for low-voltage logic translation and external pull-up flexibility.

Comparators Applications

• Hybrid electric vehicle (HEV) and electric vehicle (EV) power train systems
• Automotive infotainment and instrument cluster circuits
• Body control module signal monitoring

Comparators Procurement Notes

Verify the specific package variant and ordering suffix against the manufacturer's official orderable addendum to ensure compatibility with your PCB footprint and assembly requirements. Confirm that the component meets the required AEC-Q100 qualification level for your specific automotive application environment before finalizing procurement.

Comparators Selection Notes

Select this component when designing circuits requiring precise voltage monitoring with minimal power consumption in automotive settings. The open-drain output is ideal for interfacing with different logic levels, while the fault-tolerant inputs protect against overvoltage conditions common in noisy vehicle environments.

Comparators Part Context

This part belongs to the TLV902x-Q1 family of precision automotive comparators. It shares core architectural features with the TLV903x-Q1 series, differing primarily in the output stage type. The quad-channel configuration allows multiple comparison functions to be integrated into a single compact SOIC-14 package, reducing board space compared to discrete solutions.

Comparators Replacement Considerations

The TLV9034QDRQ1 serves as a direct functional substitute within the same family, offering identical pinout and performance characteristics but utilizing a push-pull output stage instead of open-drain.
