Overview

The TUSB8044AIRGCR is a four-port USB 3.2 Gen1 (5 Gbps) hub controller that includes an integrated USB 2.0 billboard and HID-to-I2C bridge. It supports multi-transaction translator (MTT) architecture for improved performance with legacy USB 2.0 devices and features extensive battery charging support including DCP, CDP, and ACP modes.

Why Choose This Part

The TUSB8044AIRGCR offers superior legacy performance through its Multi-Transaction Translator (MTT) architecture and dual asynchronous endpoint buffers per translator. It simplifies system design by integrating complex USB Billboard and HID-to-I2C functionality directly into the hub silicon, reducing the need for external bridge microcontrollers.

Applications

Industrial USB Hubs
Utilizing the -40 to 85 degree C operating temperature range for rugged environments.
USB-C Alt-Mode Docks
Leveraging the integrated USB Billboard 1.21 functionality for DisplayPort or HDMI over USB-C.
Charging Stations
Implementing BC1.2, Galaxy, and Chinese Telecommunications YD/T 1591-2009 charging standards.
Embedded Systems Control
Using the internal USB HID to I2C bridge to control peripherals without a dedicated MCU-to-PC interface.
