Overview
The FUSB302B01MPX, produced by ON Semiconductor, is a programmable USB Type-C controller that integrates the physical layer of the USB BMC (BMC - Bus Margining Controller) power delivery protocol. This component is designed for system designers who need to implement a DRP (Data Role Provider)/SRC (Source)/SNK (Sink) USB Type-C connector with a low level of programmability. It supports up to 100 W of power and role swap, making it versatile for various applications.
The FUSB302B enables USB Type-C detection, including attach and orientation detection, and supports full Type-C 1.2 specifications. It can operate as a dedicated host, dedicated device, or in a dual-role configuration, providing flexibility in system design.
