TPS2549 USB Charging Port Controller

The TPS2549 device is a USB charging port controller and power switch with a current-sense output that is able to control an upstream supply. This allows it to maintain 5 V at the USB port even with heavy heavy charging currents. This is important in systems with long USB cables where significant v.
