Product Introduction

Overview

The TUSB8020B-Q1 is a two-port USB 3.0 compliant hub designed by Texas Instruments. This device supports simultaneous SuperSpeed USB and high-speed/full-speed connections on the upstream port, and provides SuperSpeed USB, high-speed, full-speed, or low-speed connections on the downstream ports. It is particularly suited for applications requiring advanced USB connectivity and power management.

The hub operates within an industrial temperature range of -40°C to 85°C and is available in a 48-terminal HTQFP package. It supports various battery charging protocols, including USB Battery Charging Specification Revision 1.2 and the Chinese Telecommunications Industry Standard YD/T 1591-2009.

The TUSB8020B-Q1 also features per port or ganged power switching and over-current protection, enhancing system reliability and fault tolerance. Customization options include OTP ROM, serial EEPROM, or I2C/SMBus slave interface for configuring VID, PID, and other port settings.
