Texas Instruments TUSB8041 Four-Port Super-Speed USB 3.0 Hubs

Texas Instruments TUSB8041 Four-Port Super-Speed USB 3.0 Hubs provide simultaneous SuperSpeed USB and high-speed/full-speed connections on the upstream port. It also provides SuperSpeed USB, high-speed, full-speed, or low-speed connections on the downstream ports. When the upstream port is connected to an electrical environment that only supports high-speed or full-speed/low-speed connections, SuperSpeed USB connectivity is disabled on the downstream ports. When the upstream port is connected to an electrical environment that only supports full-speed/low-speed connections, SuperSpeed USB and high-speed connectivity are disabled on the downstream ports. The TUSB8041 supports per port or ganged power switching and over-current protection, and supports battery charging applications.
