TUSB1021RGFRQ1

Overview

The TUSB1021RGFRQ1 is a USB Type-C receptacle controller designed for automotive applications, certified to AEC-Q100 standards. It manages the USB Type-C CC lines and integrates an I2C-compatible interface for configuration and status monitoring. The device supports USB Power Delivery (PD) 3.0 and includes built-in protection features such as over-voltage and over-current detection. Operating within a supply voltage range of 2.97V to 5.5V, it functions reliably across an industrial temperature range of -40°C to +125°C. Packaged in a compact 16-pin VQFN (3x3mm) format with exposed pad, it facilitates robust integration into high-speed data and power delivery systems.

Feature Summary

• Integrated USB Type-C CC line management with PD 3.0 support
• I2C interface for host control and status reporting
• Built-in hardware protection against over-voltage and over-current events
• Automotive-grade reliability with AEC-Q100 certification

Applications

• Automotive infotainment systems requiring USB-C connectivity
• Vehicle docking stations and charging ports
• In-car data hubs and peripheral interfaces

Procurement Notes

Verify the specific suffix RGFRQ1 matches the required package and tape-and-reel quantity. Confirm AEC-Q100 qualification documentation is available for automotive compliance audits. Ensure the design accounts for the 16-pin VQFN thermal pad requirements for proper heat dissipation during operation.

Selection Notes

Select this component when a dedicated USB Type-C controller with integrated CC logic and I2C control is required for automotive environments. It is suitable for designs needing PD 3.0 compliance without external protocol chips. Consider the 16-pin VQFN footprint for space-constrained PCB layouts.

Part Context

This part belongs to Texas Instruments' TUSB102x family of USB Type-C controllers. It shares functional similarities with other members like the TUSB1020 but may differ in pinout or specific feature sets. It is distinct from signal conditioners like the TUSB215, focusing instead on port management and power delivery negotiation.

Replacement Considerations

Direct substitutes include other TUSB102x variants if pin compatibility allows. Verify that any replacement maintains AEC-Q100 certification and identical I2C register maps for seamless firmware integration.
