The FUSB302T targets system designers looking to implement a USB Type-C wall charger or Travel Adaptor. In addition to the default SRC function, the device supports DRP/ SRC/ SNK with low amount of programmability.
The FUSB302T enables the USB Type-C detection including attach/detach, and orientation. The FUSB302T integrates the physical layer of the USB BMC Power Delivery protocol to allow up to 100 W of power and role swap. The BMC PD block enables full support for alternative interfaces of the Type-C specification.
Reference code is available for the FUSB302T for easy implementation of Type-C and USB BMC Power Delivery protocol across several embedded controller platforms. Click on the Software link below.
