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. 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℃.
