• Supports autonomous Dual Role Port (DRP) functionality optimized for portable applications
• Includes integrated 2.5W switch for active cable V_CONN power delivery

Specialized Applications

• Smartphones
• Tablets and notebooks
• Wall chargers and power banks

Specialized Procurement Notes

Verify the specific suffix 'IYFPR' against official Texas Instruments documentation to confirm pinout, tape-and-reel specifications, and moisture sensitivity level. Ensure the procurement source provides valid RoHS compliance data and confirms the operating temperature range matches industrial standards before finalizing orders.

Specialized Selection Notes

Select this component when designing USB Type-C ports requiring integrated PD PHY and CC logic management via I2C. It is suitable for applications needing software-configurable DFP, UFP, or DRP roles. Consider its low current consumption and integrated over-temperature sensing for compact portable designs.

Specialized Part Context

This part belongs to the Texas Instruments USB Type-C ecosystem, specifically designed to simplify port controller design by integrating the TCPCi. It complements other TI interface solutions by handling complex USB Type-C negotiation and power delivery tasks autonomously under TCPM supervision.
