TPS25831QWRHBTQ1

Power Management - Specialized Overview

The TPS25831QWRHBTQ1 is an automotive-grade USB Type-C and BC1.2 compliant synchronous buck converter manufactured by Texas Instruments. It operates with a wide input voltage range of 5V to 36V, delivering a regulated 5V output at up to 3.5A. The device integrates cable compensation to maintain accurate output voltage despite line drops. It is housed in a 32-pin VQFN package and qualified to AEC-Q100 standards for operation across the -40°C to +125°C temperature range.

Power Management - Specialized Feature Summary

• Integrates synchronous buck conversion with dedicated cable compensation circuitry to ensure precise load regulation over varying cable lengths.
• Supports USB Type-C and BC1.2 charging protocols for compatible device detection and power negotiation.
• Designed for automotive environments with AEC-Q100 qualification and extended industrial temperature capability.

Power Management - Specialized Applications

• Automotive infotainment systems requiring robust USB charging ports
• In-vehicle display units with integrated USB connectivity
• Automotive telematics control units (TCUs)

Power Management - Specialized Procurement Notes

Verify the complete part number including suffixes to confirm specific tape-and-reel quantities and packaging variations. Confirm that the Q1 designation aligns with your project's automotive qualification requirements. Ensure the VQFN package thermal characteristics match your PCB layout capabilities for adequate heat dissipation under full load conditions.

Power Management - Specialized Selection Notes

Select this component when designing automotive USB ports requiring high current delivery and precise voltage regulation over long cables. It is suitable for applications needing BC1.2 compliance without external protocol controllers. Consider the thermal performance of the VQFN package relative to your enclosure constraints and ambient operating temperatures.

Power Management - Specialized Part Context

This part belongs to the TPS2583xA-Q1 family of automotive USB power management ICs. It shares functional similarities with other members like the TPS25830-Q1 but may differ in specific pin configurations or internal protection thresholds. The family is designed to simplify USB power delivery in vehicles by combining regulation and protocol support in a single compact solution.

Power Management - Specialized Replacement Considerations

Direct substitutes within the same family include TPS25830QWRHBTQ1. Verify compatibility regarding pinout and thermal specifications before substitution. Other variants in the series may offer different current ratings or feature sets.
