SGM7220 USB Type-C Configuration Channel Logic and Port Control GENERAL DESCRIPTION The SGM7220 enables USB Type-C ports with the Configuration Channel (CC) logic needed for Type-C interface. The SGM7220 uses the CC pins to determine port attachment and detachment, cable orientation, role detection and port control for Type-C current mode. The SGM7220 can be configured as a downstream facing port (DFP), an upstream facing port (UFP) or a dual role port (DRP) making it ideal for most applications. The SGM7220 alternates configuration as a DFP or an UFP according to the Type-C specifications. The CC logic block monitors the CC1 and CC2 pins for pull-up or pull-down resistances to determine when a USB port has been attached, the orientation of the cable and the role detected.
