3 Description
The TUSB322I device enables USB Type-C ports
with the configuration channel (CC) logic required for
Type-C ecosystems. The TUSB322I device uses the
CC pins to determine port attach and detach, cable
orientation, role detection, and port control for Type-C
current mode. The TUSB322I device can be
configured as a downstream facing port (DFP),
upstream facing port (UFP), or a dual role port (DRP),
making the TUSB322I device ideal for any
application.
The TUSB322I device alternates configuration as a
DFP or UFP according to the Type-C Specifications.
The CC logic block monitors the CC1 and CC2 pins
for pullup or pulldown 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 attach in UFP
and DRP modes. The TUSB322I will supply VCONN
when an active cable is detected.
The device operates over a wide supply range and
has low-power consumption. The TUSB322I device is
available in industrial temperature ranges.
