5 Description (continued)

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.
