3 Description
The TUSB4020BI is a two-port USB 2.0 hub, which
provides USB high-speed/full-speed connections on
the upstream port and high-speed, full-speed, or
low-speed connections on the two downstream
ports. When the upstream port is connected to an
electrical environment that supports high-speed and
full-speed/low-speed connections, high-speed and
full-speed/low-speed USB connectivity is enabled
on the downstream ports. When the upstream
port is connected to an electrical environment that
only supports full-speed/low-speed connections, highspeed
connectivity are disabled on the downstream
ports.
The TUSB4020BI supports per port or ganged power
switching and overcurrent 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 overcurrent event, only
power to the affected downstream port is switched off.
A ganged hub switches on power to all the
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 overcurrent event, power to all downstream
ports is switched off.
The TUSB4020BI downstream ports provide support
for battery charging applications by providing
battery charging connected downstream port (CDP)
handshaking support. The device also supports a
dedicated charging port (DCP) mode when the
upstream port is not connected. The DCP mode
supports USB devices which support the USB Battery
Charging and the 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 is
unconnected.
The TUSB4020BI provides terminal strap configuration for some features (including battery charging support)
and customization through OTP ROM, I2C EEPROM or an I2C/SMBus target interface for PID, VID, custom port
and phy configurations. Custom string support is also available when using an I2C EEPROM or the I2C/SMBus
target interface.
The device is available in a 48-pin HTQFP package and is offered in an industrial version for operation over the
temperature range of –40°C to 85°C.
