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.
The TUSB8020B-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.
