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 providin...
