Overview
The TUSB1021RGFTQ1 is a USB Type-C receptacle controller manufactured by Texas Instruments, designed for automotive applications. It supports USB Power Delivery (PD) and DisplayPort Alternate Mode over USB Type-C connections. The device integrates a CC logic block, an I2C interface, and a hardware watchdog timer to ensure reliable operation. It operates within a supply voltage range of 3.0 V to 5.5 V and functions across a temperature range of -40°C to +125°C. The component is housed in a 16-pin WSON package with dimensions of 3 mm x 3 mm.
Feature Summary
- Integrates USB Type-C CC logic for source/sink detection and power role determination
- Supports DisplayPort Alternate Mode signaling through integrated mux control
- Includes hardware watchdog timer for system fault recovery without host intervention
Applications
- Automotive infotainment systems requiring USB-C connectivity
- Vehicle docking stations supporting data and display output
- Car chargers implementing USB Power Delivery specifications
Procurement Notes
Verify the AEC-Q100 qualification status for automotive reliability requirements. Confirm the specific suffix RGFTQ1 matches the required tape-and-reel packaging format. Ensure the design complies with the specified operating temperature range for automotive environments. Cross-reference the pinout with the official datasheet to prevent layout errors during PCB assembly.
Selection Notes
Select this component when USB Type-C PD and DP Alt Mode are required in automotive-grade designs. Compare against the non-automotive TUSB1021 variant if environmental ratings differ. Evaluate the integration level against discrete CC logic solutions to reduce bill of materials. Verify compatibility with the host microcontroller's I2C interface speed and voltage levels.
Part Context
This part belongs to the TUSB102x series of USB Type-C controllers from Texas Instruments. The series focuses on providing robust Type-C compliance for high-speed data and power delivery. The TUSB1021 variant specifically targets applications needing DisplayPort Alternate Mode support alongside standard USB charging capabilities.
Replacement Considerations
The non-automotive grade TUSB1021RGFT may serve as a functional substitute if automotive qualification is not required. Verify that the pinout and electrical characteristics remain identical before substitution.
