Product Overview
FUSB302BMPX is a programmable onsemi USB Type-C port controller that integrates CC-pin attach/orientation detection with the BMC physical layer used by USB Power Delivery. A host processor implements the higher-level policy while the FUSB302B handles Type-C analog detection and PD packet-level functions.
The controller supports source, sink and dual-role behavior and includes dead-battery sink support plus VCONN switching for electronically marked/full-featured cables.

FUSB301 vs FUSB302B
FUSB301 is primarily an autonomous Type-C CC controller, while FUSB302B adds the USB Power Delivery physical layer and expects host software to implement the PD policy stack. The two parts should not be treated as functionally interchangeable.
