TPS2071EVM-159
Development Tools, Evaluation Module For Power Controller For Bus/Self Powered Hub W/5V LDO Control, 3.3V LDO, 8 Power Switches ACTHI
The is an evaluation module provides a convenient method for evaluating the performance of a hybrid bus powered/self poweredhub using the TPS2071 USB Hub Power Controller. A complete designed and tested USB hub is presented. The hub is an evaluation module that can deliver up to 0.5A of continuous output current in self powered mode or up to 0.1A of continuous output current in bus powered mode. The universal serial bus USB interface is a four line multiplexed serial bus designed for low to high speed PC peripherals. The maximum speed of the USB 1.1 interface is 12Mb/s, while USB 2.0 can operate at up to 480Mb/s. The four line USB interface was conceived for dynamic attach detach hot plug unplug of peripheral devices. Two lines are provided for differential data and two lines are provided for 5V power distribution.
