Two-port USB 2.0 hub provides upstream and downstream connection versatility

This post is sponsored by Texas Instruments. The Texas Instruments (TI) TUSB4020BI is a two-port USB 2.0 hub which provides high-speed / full-speed connections on the upstream port and provides high-speed, full-speed, or low-speed connections on the two downstream ports. When the upstream port is connected to an electrical environment that supports high-speed and full-speed/low-speed connections, high-speed and full-speed/low-speed USB connectivity is enabled on the downstream ports. When the upstream port is connected to an electrical environment that only supports full-speed/low-speed connections, high-speed connectivity are disabled on the downstream ports. The TUSB4020BI supports per port or ganged power switching and over-current protection.
