Abstract
A Universal Serial Bus (USB) controller including a Vconn switch having a current controlled architecture, and method for operating the same, are described. In an example embodiment, the Vconn switch includes first and second transistors coupled in series between a Vconn terminal and a communication channel (CC) terminal, a replica switch coupled to the Vconn terminal, a replica current generator coupled to the replica switch, and a resistance control module coupled to the replica current generator. The replica current generator is operable to match a current through the replica switch to the current supplied to the CC terminal through the first and second transistors. The resistance control module is operable to use a digital output of a current inverter to control an in-rush current to the CC terminal.
