TLV9031QDCKRQ1

Comparators Overview

The TLV9031QDCKRQ1 is a single-channel, automotive-grade 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, an input offset voltage of 300 μV, 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 capacitive 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.

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 'DCK' corresponds to the SC-70 package and 'Q1' indicates AEC-Q100 qualification before procurement. Confirm the pinout configuration matches the standard North West arrangement for the TLV90x1-Q1 variant. Ensure the component meets the required ambient operating temperature range of -40°C to +125°C for the target application environment.

Comparators Selection Notes

Select this component when a single-channel comparator with a push-pull output is required for automotive environments. It is suitable for designs needing low quiescent current and high precision input offset voltage. Consider alternative pinouts like the TLV90x0-Q1 if a South East pin configuration is preferred for board layout optimization.

Comparators Part Context

This part belongs to the TLV902x-Q1 and TLV903x-Q1 family of precision automotive comparators. The family offers single, dual, and quad channel options with varying output types. The TLV9031-Q1 specifically provides the single-channel variant with a push-pull output, distinguishing it from the open-drain TLV902x-Q1 series.

Comparators Replacement Considerations

The TLV9021QDCKRQ1 serves as a functional substitute within the same family but utilizes an open-drain output instead of a push-pull stage. Designers must account for the need for external pull-up resistors when replacing the TLV9031QDCKRQ1 with the TLV9021QDCKRQ1.
