Description
General part information
TPS2549-Q1 Series
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.
The TP2549-Q1 47-mΩ power switch has two selectable, programmable current limits that support port power management by providing a lower current limit that can be used when adjacent ports are experiencing heavy loads. This is important in systems with multiple ports and an upstream supply unable to provide full current to all ports simultaneously.
