It provides simultaneous Super Speed USB and high-speed/full-speed connections on the upstream port and provides Super Speed USB, high-speed, fullspeed, 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, Super Speed USB connectivity is disabled on the downstream ports. When the upstream port is connected to an electrical environment that only supports fullspeed/low-speed connections, Super Speed USB and high-speed connectivity are disabled on the downstream ports. The TUSB8020B-Q1 supports per port or ganged power switching and over-current protection, and supports battery charging applications. An individually port power controlled...
