TUSB2046BIRHBT Description

Short technical summary and product information.

The TUSB2046BIRHBT from Texas Instruments is a 3.3-V CMOS hub device that provides one upstream port and four downstream ports, fully compliant with the Universal Serial Bus (USB) specification as a full-speed hub. This controller implements a digital state machine, eliminating the need for firmware programming. It integrates fully compliant USB transceivers for all ports, supporting full-speed and low-speed devices on downstream ports.

 

The device operates within a temperature range of -40°C to 85°C and requires a voltage supply between 3V and 3.6V. It features a 32-pin VQFN package with an exposed pad, measuring 5x5mm. The TUSB2046BIRHBT supports both self-powered and bus-powered modes, with integrated power switching and overcurrent reporting. It also supports suspend and resume operations and can be configured with programmable Vendor ID and Product ID using an external serial EEPROM.

 

Designed for ease of use, the TUSB2046BIRHBT works seamlessly with any operating system with a USB stack. Its package pinout allows for a 2-layer PCB, and it achieves low EMI emissions through a 6-MHz crystal input. This hub controller is migrated from the proven TUSB2040 hub, offering a lower cost and enhanced system ESD performance.
