TLV9020QDCKRQ1

Comparators Overview

The TLV9020QDCKRQ1 is an automotive-grade, single-channel precision comparator from Texas Instruments. It operates within a supply voltage range of 1.65V to 5.5V and features fault-tolerant inputs capable of withstanding up to 6V without damage or phase inversion. The device includes a Power-On Reset (POR) circuit to ensure known output states during power transitions. It offers a typical propagation delay of 100ns and low quiescent current consumption of 16μA per channel.

Comparators Feature Summary

• Precision input offset voltage of 300μV for accurate voltage monitoring
• Fault-tolerant inputs allow signals up to 6V without damaging the device
• Integrated Power-On Reset (POR) prevents output transients during system startup
• Rail-to-Rail input voltage range exceeds the supply rails

Comparators Applications

• HEV/EV and power train systems
• Infotainment and cluster applications
• Body control modules

Comparators Procurement Notes

Verify the specific ordering suffix to confirm the package type and pinout configuration. Ensure the selected variant matches the required output stage, as the TLV902x-Q1 series utilizes open-drain outputs while other family members may differ. Confirm AEC-Q100 qualification status and temperature grade requirements for the target automotive application environment.

Comparators Selection Notes

Select this component for applications requiring high precision and fault tolerance in harsh automotive environments. The open-drain output allows flexibility in pull-up voltage selection, suitable for interfacing with various logic levels. Consider the low quiescent current for battery-powered systems and the rail-to-rail input capability for maximizing dynamic range near supply rails.

Comparators Part Context

This part belongs to the TLV902x-Q1 and TLV903x-Q1 Precision Automotive Comparator Family. The family provides single, dual, and quad channel options with consistent electrical characteristics across configurations. The TLV9020-Q1 specifically denotes the single-channel variant with an open-drain output, designed for compact SC-70 packaging.
