General Description

The TPS2549-Q1 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 charging currents.

This is important in systems with long USB cables where significant voltage drops can occur while fast-charging portable devices.
