Abstract
In one embodiment, a current source is coupled to a channel input of a switch, and an output of the switch is coupled to a positive or negative data line in a USB 2.0 communication system. In addition, a first input of the voltage threshold comparator is coupled to the negative data line, a second input of the voltage threshold comparator is coupled to a positive data line, and an output of the voltage threshold comparator is coupled to a control input of the switch.
