3 Description
TUSB422 is a USB PD PHY that enables a USB
Type-C port with the Configuration Channel (CC)
logic needed for USB Type-C ecosystems. It
integrates the physical layer of the USB BMC power
delivery (PD) protocol to allow up to 100-W of power
and support for alternate mode interfaces. An
external microprocessor, containing USB Type-C Port
Manager (TCPM), communicates with the TUSB422
through an I²C interface.
Under control of the TCPM, TUSB422 uses the CC
pins to determine port attach/detach, cable
orientation, role detection, and port control for USB
Type-C current mode. The TUSB422 can be
configured as DFP, UFP, or DRP, depending on the
application. The TUSB422 implements VBUS
detection and discharge for the implementation of a
compliant USB Type-C port.
The TUSB422 integrates 2.5 Watt switch to provide
VCONN power for an active cable. The device also
provides VCONN discharge function. The TUSB422
also supports USB Type-C optional features such as
audio and debug accessory.
The device operates over a wide supply-range and
has low power consumption. The TUSB422 is
available in industrial temperature ranges.
