The RT9752 is a USB Type-C Downstream Facing Port (DFP) controller with back to back power switch which offers 28V tolerance on VOUT pin at off state and 3A rated supply current for VBUS for USB Type-C applications. The RT9752 have Configuration Channel (CC) function to determine when USB device is attached. If the Upstream Facing Port (UFP) is attached using an E-marked cable, the RT9752 also applies power to VBUS and VCONN power to the cable CC pin. The RT9752 also identifies when Type-C audio or debug accessories are attached. Reverse voltage protection is provided to prevent reverse current flowing back to input power supply in a power source swap application.
