TUSB217ARWBTQ1

Overview

The TUSB217ARWBTQ1 is an automotive-grade USB 2.0 high-speed signal conditioner designed to compensate for transmission channel losses. It utilizes patented edge boosting and DC boosting functions to accelerate signal transitions and improve static levels, while pre-equalization mitigates intersymbol interference in long cable applications. The device supports Low Speed (LS), Full Speed (FS), and High Speed (HS) modes with a maximum data rate of 480 Mbps. It operates within a supply voltage range of 2.3 V to 6.5 V and functions reliably across an extended temperature range from -40°C to +105°C. Packaged in a compact 12-X2QFN (1.6x1.6 mm) format, it integrates BC 1.2 charging controllers.

Feature Summary

• Compensates for AC and DC transmission losses using edge boosting and DC boosting technologies
• Supports USB 2.0, OTG 2.0, and BC 1.2 protocols with integrated battery charging controllers
• Configurable signal enhancement and RX equalization settings via external resistors and pins
• Compatible with upstream TUSB211/212/214/216 devices for daisy-chained high-loss applications

Applications

• Automotive infotainment systems and docking stations
• Laptops and desktop computers requiring extended connectivity
• Portable electronic devices and tablets
• Active cables and cable extenders up to 10 meters

Procurement Notes

Verify the specific suffix 'RWBT' against the manufacturer's official datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the component meets AEC-Q100 automotive qualification requirements if deployed in vehicle environments. Cross-reference the RoHS status and moisture sensitivity level prior to assembly planning.

Selection Notes

Select this component when system design requires compensation for high-loss channels exceeding standard USB 2.0 limits. It is suitable for applications needing integrated BC 1.2 charging functionality without additional discrete components. Consider daisy-chaining multiple units for distances beyond 5 meters. Verify that the 12-X2QFN footprint aligns with PCB layout constraints.

Part Context

This part belongs to the TUSB217A series of USB 2.0 signal conditioners manufactured by Texas Instruments. It serves as an automotive-qualified variant within the family, offering signal integrity improvements for high-speed data transmission. The series includes various packages and grades, with this model specifically tailored for robust performance in electrically noisy or lossy environments.

Replacement Considerations

The TUSB217ARWBRQ1 is a pin-compatible alternative within the same series. Verify if the non-automotive grade or different packaging option meets project requirements. No other direct substitutes are confirmed in public documentation.
