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. The CC logic detects the Type-C current mode as default, medium or high depending on the role detected. VBUS detection is implemented to determine a successful attachment in UFP and DRP modes.
The SGM7220 operates over a wide supply range and has low power consumption. The device is available in a Green UTQFN-1.6×1.6-12L package and operates in industrial and commercial temperature range of -40℃ to +125℃.
