TPS25832QCWRHBRQ1

Power Management - Specialized Overview

The TPS25832QCWRHBRQ1 is an automotive-grade USB Type-C and BC1.2 compliant sink controller manufactured by Texas Instruments. Designed for high-voltage input applications, it supports a wide input voltage range from 5V to 36V. The device integrates a synchronous buck converter capable of delivering up to 3.5A output current. It features cable compensation to ensure accurate voltage delivery at the load. The component operates within an extended temperature range of -40°C to 125°C and is housed in a compact 32-VQFN package suitable for space-constrained automotive designs.

Power Management - Specialized Feature Summary

• Integrates a synchronous buck converter with integrated power switches for efficient step-down regulation.
• Supports USB Type-C and BC1.2 charging protocols for compatible host communication.
• Includes cable compensation circuitry to maintain precise output voltage under varying load conditions.
• Automotive qualification ensures reliability and performance across extreme temperature environments.

Power Management - Specialized Applications

• Automotive infotainment systems requiring robust USB charging capabilities
• In-vehicle display units and navigation modules
• Electronic control units (ECUs) with external peripheral connectivity

Power Management - Specialized Procurement Notes

Verify that the specific ordering suffix matches the required tape-and-reel packaging configuration. Confirm that the Q1 designation aligns with your automotive quality management standards. Ensure the thermal pad connection on the VQFN package is properly implemented during assembly to meet the specified maximum operating temperature of 125°C. Cross-reference the pinout with your PCB layout to prevent interface mismatches.

Power Management - Specialized Selection Notes

Select this component when a combined USB sink controller and DC-DC buck regulator is required for automotive applications. It is suitable for systems needing to draw power from USB hosts while managing higher voltage inputs up to 36V. Consider the integrated cable compensation feature if long cable runs are present in the design. Evaluate the 32-VQFN footprint against available board space constraints.

Power Management - Specialized Part Context

This part belongs to the TPS2583x-Q1 family of automotive USB sink controllers. It shares functional similarities with other members like the TPS25831-Q1 but may differ in specific pin configurations or internal protection thresholds. The series is designed to simplify USB Type-C integration in vehicles by combining protocol handling with power conversion.

Power Management - Specialized Replacement Considerations

Direct substitutes include the TPS25831-Q1 and TPS25833-Q1. Verify compatibility regarding the specific output current limits and package pin assignments before swapping. Ensure that any replacement maintains the same automotive grade and voltage input specifications.
