TLV9021QDBVRQ1

Comparators Overview

The TLV9021QDBVRQ1 is a single-channel precision automotive comparator from Texas Instruments, housed in an SOT-23-5 package. It operates on a supply voltage range of 1.65 V to 5.5 V with a quiescent current of 17.1 µA. The device features a typical propagation delay of 100 ns and an input offset voltage of 300 µV. It includes Power-On Reset (POR) functionality and fault-tolerant inputs capable of withstanding up to 6 V without damage.

Comparators Feature Summary

• Features rail-to-rail input voltage range that exceeds the supply rails for enhanced signal detection capability.
• Includes integrated Power-On Reset (POR) circuitry to ensure known output states during system power-up and power-down sequences.
• Provides fault-tolerant inputs that can withstand voltages up to 6 V without causing output phase inversion or damage.

Comparators Applications

• Hybrid Electric Vehicle (HEV) and Electric Vehicle (EV) power train systems
• Automotive infotainment and instrument cluster circuits
• Body control module applications

Comparators Procurement Notes

Verify the specific ordering suffix matches the required pinout configuration, as the TLV90x1-Q1 variant utilizes a standard North West pinout distinct from other family members. Confirm AEC-Q100 qualification status and temperature grade requirements align with the target automotive application environment before finalizing procurement specifications.

Comparators Selection Notes

Select this component when a low-power, high-precision comparator with fault-tolerant inputs is required for automotive environments. The open-drain output allows for flexible pull-up configurations suitable for logic translation. Ensure the design accounts for the specific North West pinout arrangement associated with the DBVR package variant.

Comparators Part Context

This device belongs to the TLV902x-Q1 and TLV903x-Q1 precision automotive comparator family. While sharing core electrical characteristics such as low offset voltage and speed-to-power efficiency, it differs from the TLV903x-Q1 series by utilizing an open-drain output stage instead of a push-pull configuration. This distinction impacts drive capability and interface compatibility within the broader product line.

Comparators Replacement Considerations

TLV9020QDBVRQ1 offers identical electrical performance but uses a South East pinout configuration. TLV9031QDBVRQ1 provides similar precision and speed but features a push-pull output stage instead of open-drain. Verify pinout compatibility and output stage requirements when substituting these alternatives.
