TLV9031QDBVRQ1

Comparators Overview

The TLV9031QDBVRQ1 is an automotive-grade, single-channel precision analog comparator from Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features a push-pull output stage. Key electrical specifications include a typical quiescent current of 18 μA per channel, a maximum input offset voltage of ±2 mV across the temperature range, and a typical propagation delay of 100 ns. The device supports rail-to-rail inputs that exceed the supply rails and includes Power-On Reset (POR) functionality.

Comparators Feature Summary

• Features a push-pull output stage capable of sourcing and sinking milliamps of current to drive loads such as LEDs or MOSFET gates.
• Includes integrated Power-On Reset (POR) circuitry to ensure the output remains in a known state until the minimum supply voltage is reached.
• Provides fault-tolerant inputs that can withstand voltages up to 6 V without damage or phase inversion.
• Delivers precision performance with low input offset voltage and low quiescent current for efficient power management.

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 DBVR corresponds to the SOT-23-5 package and standard North West pinout configuration. Confirm AEC-Q100 qualification status and Device Temperature Grade 1 compliance for your target operating environment. Ensure input signals are current-limited if they exceed the supply rails by more than 0.3 V to prevent damage.

Comparators Selection Notes

Select this component when a single-channel comparator with push-pull outputs is required for automotive environments. It is suitable for designs needing rail-to-rail input capability exceeding the supply rails and precise voltage monitoring. Consider the 1.65 V to 5.5 V supply range and low quiescent current for battery-powered or energy-efficient applications.

Comparators Part Context

This part belongs to the TLV902x-Q1 and TLV903x-Q1 family of precision automotive comparators. While the TLV902x-Q1 variants offer open-drain outputs, the TLV903x-Q1 series specifically provides push-pull outputs. The family shares common features like fault-tolerant inputs and POR, but differs in output stage topology and available package options.

Comparators Replacement Considerations

Direct functional substitutes within the same family include TLV9030QDBVRQ1, which shares identical electrical characteristics but utilizes an alternate South East pinout configuration on the SOT-23-5 package. Other members of the TLV903x-Q1 series may be considered if multiple channels are needed, though pinouts will differ.
