TUSB422IYFPT

Specialized Overview

The TUSB422IYFPT is a USB PD TCPCi port controller from Texas Instruments designed for USB Type-C ecosystems. It integrates the USB BMC physical layer for Power Delivery protocols, supporting power sourcing and sinking up to 100W (5V to 24V). The device communicates with an external TCPM via an I2C interface to manage CC logic, role detection, and cable orientation. Key electrical parameters include a VDD supply voltage range of 2.7V to 5.5V and an industrial operating temperature range of –40°C to 85°C. It features an integrated 2.5W switch for active cable VCONN power and includes over-temperature sensing and VBUS detect/discharge control capabilities.

Specialized Feature Summary

• Integrates USB BMC physical layer for USB PD protocol handling
• Supports autonomous Dual Role Port (DRP) operation
• Includes integrated 2.5W VCONN switch for active cables
• Provides software configurability as DFP, UFP, or DRP

Specialized Applications

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

Specialized Procurement Notes

Verify the specific suffix 'IYFPT' against official Texas Instruments documentation to confirm package type, tape-and-reel specifications, and temperature grade. Ensure the component matches the required RoHS compliance status and lead finish details specified in the manufacturer's current datasheet before procurement.

Specialized Selection Notes

Select this component when a dedicated USB Type-C port controller with integrated BMC PHY is required. It is suitable for designs needing I2C-controlled CC logic and support for USB PD specifications up to 100W. Consider its industrial temperature range and low current consumption for portable applications requiring robust role detection and alternate mode negotiation.

Specialized Part Context

This part belongs to the TUSB422 family of USB Type-C port controllers. It serves as a bridge between the host microprocessor and the USB Type-C connector, handling complex signaling and power management tasks autonomously under TCPM supervision. The device simplifies design by integrating physical layer functions typically handled by separate components.

Specialized Replacement Considerations

Consult Texas Instruments documentation for officially confirmed substitute part numbers within the same product family or compatible series. Verify pinout compatibility and functional equivalence before considering any alternative components.
