Texas Instruments TUSB4041I Four-Port USB 2.0 Hub

Texas Instruments TUSB4041I/TUSB4041I-Q1 Four-Port USB 2.0 Hub provides USB high-speed or full-speed connections on the upstream port. The device offers USB high, full, or low-speed connections on the downstream ports. When the upstream port is connected to an electrical environment that only supports high, full, and low-speed connections, the USB high, full, and low-speed connectivity is enabled on the downstream ports. When the upstream port is connected to an electrical environment that only supports full or low-speed connections, the USB high-speed connectivity is disabled on the downstream ports. The TUSB4041I/TUSB4041I-Q1 supports per-port or ganged power switching, overcurrent protection, and battery charging applications. The Texas Instruments TUSB4041I-Q1 devices are AEC-Q100 qualified for automotive applications.
