Overview

The TUSB8041RGCT is a four-port USB 3.0 hub controller providing simultaneous SuperSpeed and high-speed/full-speed connections on the upstream port. It is designed to provide full backward compatibility with USB 2.0 and 1.1 environments while supporting modern 5 Gbps data rates. The device includes support for battery charging applications and features integrated voltage regulators to simplify power delivery.

Why Choose This Part

The TUSB8041RGCT offers flexible configuration via I2C, SMBus, or external EEPROM, allowing engineers to customize vendor and product IDs. Its low power consumption is optimized with a 1.1V core voltage and support for USB Link Power Management states (U1, U2, and U3). The 64-VQFN package includes an exposed pad for efficient thermal dissipation in compact designs.

Applications

High-Speed Docking Stations
Providing multiple USB 3.0 ports for laptops and tablets while maintaining backward compatibility for legacy peripherals.
Industrial Hubs
Robust USB expansion in industrial control systems requiring reliable 5 Gbps data throughput.
Digital Televisions
Expanding internal connectivity for smart TVs to support multiple external media drives and input devices.
Embedded System Expansion
Adding high-speed peripheral connectivity to single-board computers or custom embedded platforms via I2C or SMBus configuration.

Getting Started

Engineers should evaluate the design using the TUSB8041EVM evaluation module to verify signal integrity at SuperSpeed rates. The device requires a 24 MHz crystal or oscillator for operation and dual power rails of 1.1V and 3.3V. Configuration can be handled through hardware strapping pins for rapid prototyping or via the I2C interface for advanced register control.
