TI公司的USB Type-C坞站提供数据和视频端口扩展和支持USB PD/Alternate模式协议的Type-C系统的充电功能,采用20V DC IN供电,包括USB3.0集线器TUSB8041,提供mini DP源连接器,以连接DisplayPort沉,协议转换器或USB集线器.本文介绍了USB3.0集线器TUSB8041主要特性,框图,USB Type-C坞站参考设计主要特性,框图,电路图,材料清单和PCB设计图.

The Type-C Dock Board is designed to help evaluate Type-C Dock implementations with video and charging support. The Type-C Dock offers data and video port expansion and a charging capability for Type-C systems that support USB PD/Alternate mode protocol.  The dock comes with three downstream facing ports: two Type C DFP only ports with max of 5V@3A VBUS power, one Type-A DFP port with BC1.2 support.  A DisplayPort connector is also provided for video sink connection: A direct connect to a DisplayPort monitor, connection to a MST HUB or a DP protocol converter to a monitor.

The TUSB8041 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.

The TUSB8041 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.

The TUSB8041 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 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 RGC package and is offered in a commercial version (TUSB8041) for operation over the temperature range of 0℃ to 70℃, and in an industrial version (TUSB8041I) for operation over the temperature range of –40℃ to 85℃.
