Simplified Schematic
3 Description
The TUSB320LI and TUSB320HI devices (remainder
of this document called TUSB320 unless otherwise
noted) enables USB Type-C ports with the
configuration channel (CC) logic needed for Type-C
ecosystems. The TUSB320 devices use the CC pins
to determine port attach and detach, cable
orientation, role detection, and port control for Type-C
current mode. The TUSB320 devices can be
configured as a downstream facing port (DFP),
upstream facing port (UFP) or a dual role port (DRP)
making it ideal for any application.
The TUSB320 devices alternate 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. V_BUS detection is
implemented to determine a successful attach in UFP
and DRP modes.
The devices operate over a wide supply range and
have low-power consumption. The TUSB320 is
available in two versions of enable: Active low enable
called TUSB320LI and active high enable called
TUSB320HI. The TUSB320 family of devices are
available in industrial temperature ranges.
