TPS25751DREFR

Power Management - Specialized Overview

The TPS25751DREFR is a USB Type-C and USB Power Delivery controller from Texas Instruments, housed in a 38-pin WQFN package. It supports USB PD 3.2 and includes an integrated 20-V, 5-A, 15-mΩ bidirectional load switch for power path management. The device features liquid detection at the connector, I²C control for TI battery chargers, and configurable GPIOs. It operates within a supply voltage range of 3 V to 3.6 V and functions across a temperature range of -40°C to +125°C.

Power Management - Specialized Feature Summary

• Supports USB PD 3.2 with integrated bidirectional load switch
• Includes direct liquid detection at the Type-C connector
• Provides I²C control compatibility with TI battery chargers
• Features robust protection against reverse current and overvoltage

Power Management - Specialized Applications

• Power tools
• Wireless vacuum cleaners
• Personal electronics
• Industrial applications

Power Management - Specialized Procurement Notes

Verify the specific suffix 'REFR' indicates the reel packaging format as per manufacturer documentation. Confirm that the component meets RoHS standards and humidity sensitivity requirements before integration. Ensure the ordering part number matches the exact pinout and thermal pad configuration required by the design.

Power Management - Specialized Selection Notes

Select this component when a bidirectional power path is required for dual-role power applications. It is suitable for designs needing integrated protection and liquid detection without external switches. Verify compatibility with the target battery charger IC if using the I²C control feature for system optimization.

Power Management - Specialized Part Context

This part belongs to the TPS25751 family of USB Type-C controllers designed for power delivery applications. It complements other variants like the TPS25751ASRSMR, which uses a different package and integrates a sourcing switch instead of a bidirectional load switch. The family focuses on simplifying USB-C PD system design through high integration.

Power Management - Specialized Replacement Considerations

The TPS25751ASRSMR is a related variant but differs in package (VQFN-32) and internal switch configuration (sourcing vs. bidirectional). Direct replacement requires verifying pinout compatibility and ensuring the application does not rely on the specific bidirectional load switch capabilities of the DREFR variant.
