For charging with data throughput I will have a box with a cable attached that will go to a port that a consumer can then plug their USB cable into and then to their device. When charging at 2.1A charge only or 1.5A data mode there will be a drop in voltage to their Device that would likely take us below the rated USB voltage specification as I understand it is 4.75 – 5.25. For DCP it can drop to 2V.
Currently I can use 22 gauge wire which would allow 10.9 feet at 1.5A (CDP) but I can only control part of that distance. The other part would be the consumers cable to their Device ... so I need to try to maintain 5V to the end of my cable.
A competitor has a device separate from the supply that senses the voltage and then inputs to the power supply feedback. They also have a device that the supply knows something about the cable and then accounts for the loss. Can the IT solutions do this as well ?
