FA2203

The FA2203 is a USB Type-C Downstream Facing Port (DFP) controller with an integrated 3A power switch. The FA2203 monitors the CC lines to determine when a USB device is attached. If an Upstream Facing Port (UFP) device is attached, the FA2203 applies power to VBUS and communicates the selectable VBUS current sourcing capability to the UFP via the pass-through CC line. If the UFP is attached using an electronically marked cable, the FA2203 also applies VCONN power to the cable CC pin.
