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.

TUSB8041-Q1
SLLSEE6B – JULY 2014 – REVISED JANUARY 2016
The TUSB8041-Q1 downstream ports provide support for battery charging applications by providing Battery
Charging Downstream Port (CDP) handshaking support. It also supports a Dedicated Charging Port (DCP) mode
when the upstream port is not connected. The DCP mode supports USB devices which support with the USB
Battery Charging and Chinese Telecommunications Industry Standard YD/T 1591-2009. In addition, an automatic
mode provides transparent support for BC devices and devices supporting Divider Mode charging solutions when
the upstream port unconnected.
The TUSB8041-Q1 provides pin strap configuration for some features including battery charging support, and
also provides customization though OTP ROM, I2C EEPROM or via an I2C/SMBus slave interface for PID, VID,
and custom port and phy configurations. Custom string support is also available when using an I2C EEPROM or
the I2C/SMBus slave interface.
The device is available in a 64-pin PAP package and is designed for operation over the temperature range of
-40°C to 85°C.
