Texas Instruments TUSB4020BI/TUSB4020BI-Q1 High-Speed USB 2.0 Hub
Texas Instruments TUSB4020BI/TUSB4020BI-Q1 Two-Port High-Speed USB 2.0 Hub that provides USB high-speed/full-speed connections on the upstream port. It also 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 is disabled on the downstream ports. The device supports per port or ganged power switching and overcurrent protection. The TUSB4020BI-Q1 devices are AEC-Q100 qualified for automotive applications.Features
