Overview

The TUSB8044RGCT is a four-port USB 3.1 Gen 1 (5 Gbps) hub controller that provides simultaneous SuperSpeed and high-speed/full-speed connections on the upstream port. It integrates a custom Billboard Class requirement for USB Power Delivery applications and supports battery charging on all downstream ports. The device is manageable via I2C or SMBus, allowing for custom configuration of descriptors and port behaviors.

Why Choose This Part

The TUSB8044RGCT stands out by offering a fully integrated Billboard Class support, which simplifies the design of USB Power Delivery systems. It features flexible power management with 1.1V and 3.3V supply rails and maintains a low power profile of 30mA during suspend modes. The 64-VQFN package with a 0.5mm pitch provides a compact footprint for high-density PCB layouts.

Applications

USB Type-C Docking Stations
Providing high-speed data expansion for laptops and tablets while managing USB Power Delivery Billboard requirements.
Integrated Monitor Hubs
Adding downstream USB 3.1 ports to professional displays with support for peripheral charging.
Industrial PC Expansion
Expanding internal USB headers to multiple rugged external ports for industrial automation controllers.
Set-Top Boxes
Enabling multiple high-speed storage and interface connections for home media centers.

Getting Started

Designers should evaluate this controller using the TUSB8044EVM evaluation module. Configuration can be performed via external EEPROM or a system microcontroller using the I2C/SMBus interface to set vendor and product IDs. Ensure proper signal integrity practices for 5 Gbps differential pairs, including impedance-controlled traces and minimal via transitions.
