TPS2549 Datasheet (Texas Instruments) - USB Charging Port Controller

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
