Texas Instruments TUSB8020B/TUSB8020B-Q1 Two-Port USB 3.0 Hub

Texas Instruments TUSB8020B/TUSB8020B-Q1 Two-Port USB 3.0 Hub provides 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. 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 Texas Instruments TUSB8020B/TUSB8020B-Q1 supports per port or ganged power switching and overcurrent protection. The TUSB8020B-Q1 devices are AEC-Q100 qualified for automotive applications.
