The TUSB8020B 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 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 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 overcurrent event, power to all downstream ports will be switched off.

The TUSB8020B downstream ports provide support for battery charging applications by providing battery charging connected 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 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 TUSB8020B provides terminal strap configuration for some features including battery charging support, and also provides customization though OTP ROM, I2C EEPROM or through 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 48-pin HTQFP package and is offered in a commercial version (TUSB8020B) for operation over the temperature range of 0°C to 70°C and in an industrial version (TUSB8020BI) for operation over the temperature range of –40°C to 85°C.

The TUSB8020B 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.
