SG Micro SGM7220 Manual

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. V
BUS
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℃.
