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.
