Overview
The TUSB4020BIPHPRQ1 is a two-port USB 2.0 hub controller designed and manufactured by Texas Instruments. This device is specifically tailored for automotive and industrial applications, offering robust and reliable USB connectivity. It supports high-speed, full-speed, and low-speed USB connections on both the upstream and downstream ports. The hub is configured to adapt to different electrical environments, enabling high-speed connectivity when supported and disabling it when only full-speed/low-speed connections are available. The TUSB4020BIPHPRQ1 is packaged in a 48-pin HTQFP (Heat Transfer QFP) package and operates over an industrial temperature range of -40°C to 85°C, making it suitable for a wide range of environments.
