3 Description
The TUSB8041-Q1 is a four-port USB 3.0 hub. It
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.

5 Description (Continued)
The TUSB8041-Q1 supports per port or ganged power switching and over-current protection, and 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 over-current event, only power to the
affected downstream port will be switched off.
A ganged hub switches on power to all its downstream ports when power is required to be on for any port. The
power to the downstream ports is not switched off unless all ports are in a state that allows power to be removed.
Also when a ganged hub senses an over-current event, power to all downstream ports will be switched off.
