TUSB8040A www.ti.com 1.4 SLLSEA7F – MAY 2012 – REVISED SEPTEMBER 2013 Functional Description The TUSB8040A supports per port or ganged power switching and over-current protection. 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.

If a clock is provided to XI instead of a crystal, XO is left open and VSSOSC should be connected to the PCB ground plane. Otherwise, if a crystal is used, the connection needs to follow the guidelines below.
