The TUSB4041I-Q1 device is a four-port USB 2.0 hub. The device provides USB high-speed or full-speed connections on the upstream port. The device also provides 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, full-speed, and low-speed connections, the USB high-speed, full-speed and low-speed connectivity is enabled on the downstream ports. When the upstream port is connected to an electrical environment that only supports full-speed or low-speed connections, the USB high-speed connectivity are disabled on the downstream ports.

The TUSB4041I-Q1 device supports per-port or ganged power switching and overcurrent protection. The device also supports battery charging applications.

An individually port-power-controlled hub switches power on or off to each downstream port as requested by the USB host. Also when an individually port-power-controlled hub senses an overcurrent event, only power to the affected downstream port is switched off.Read more
