TUSB8020B-Q1 Automotive Two-Port USB 3.0 Hub  
1 Features  
3 Description  
The TUSB8020B-Q1 is a two-port USB 3.0 compliant  
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.

Compound Device  
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.

VID and PID  
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.
