TUSB8041A Description

Short technical summary and product information.

The Texas Instruments TUSB8041A is a versatile 4-port USB 3.1 Gen1 hub controller designed for various applications including computer systems, docking stations, monitors, and set-top boxes. It provides SuperSpeed USB and High-Speed/Full-Speed connections on the upstream port, and SuperSpeed USB, High-Speed, Full-Speed, and Low-Speed connections on the downstream ports.

Key features include support for multiple transaction translators (MTT) with two asynchronous endpoint buffers per translator. The TUSB8041A also incorporates battery charging capabilities, supporting D+/D- divider charging ports (ACP1, ACP2) and automatic mode transitions between DCP and ACP modes. It can operate as a USB 3.1 Gen1 or USB 2.0 compound device, with per-port or ganged power switching and over-current notification inputs.

This hub controller supports four external downstream ports and offers I2C master functionality with clock stretching. Custom configurations for VID, PID, port settings, and strings are supported via OTP ROM, serial EEPROM, or I2C/SMBus slave interfaces. The device requires a single 24MHz clock input and is available in a 64-pin QFN package.

The TUSB8041A is designed for reliable performance, with downstream ports configurable to USB 2.0 only. Its compact 9mm x 9mm VQFN package is suitable for space-constrained designs.
