Overview

The TUSB8041 is a four-port USB 3.0 (SuperSpeed) hub controller designed for high-performance and power-efficient multiport expansion. It supports simultaneous SuperSpeed and Hi-Speed/Full-Speed connections and includes an integrated Multi Transaction Translator for legacy USB 2.0 performance. The device is highly configurable via I2C, SMBus, or an external EEPROM to customize VID/PID and port behavior.

Why Choose This Part

It offers significant flexibility with support for per-port or ganged power switching and customizable configuration through OTP ROM or I2C. The hub provides a 128-bit UUID for unique device identification and includes a clock input supporting standard 24-MHz crystals, simplifying the BOM.

Applications

Desktop and Laptop Docking Stations
Provides reliable four-port expansion for peripherals including high-bandwidth storage and imaging devices.
Industrial Embedded PC Modules
Adds robust USB 3.0 connectivity to SBCs or carrier boards in temperature-controlled industrial environments.
Smart Monitors and Digital Signage
Integrates directly into displays to provide user-accessible high-speed peripheral ports.
USB Battery Charging Stations
Supports CDP and DCP modes, including Chinese Telecommunications Industry Standard YD/T 1591-2009, for charging mobile devices.

Getting Started

Designers can evaluate the chip using the TUSB8041EVM evaluation module. Configuration is typically handled via an external I2C EEPROM or by pulling specific pins high/low for hardware-strap selection. Ensure the thermal pad of the 64-VQFN package is properly soldered to a large ground plane for adequate heat dissipation.
