FUSB303BTMX USB Type-C port controller 12-X2QFN
The FUSB303BTMX is an onsemi fully autonomous USB Type-C port controller optimized for 15 W or lower applications, delivered in an ultra-compact 12-X2QFN body measuring 1.6 mm x 1.6 mm x 0.375 mm and supplied on 5000-piece tape-and-reel carriers . As a state-machine-based CC controller, it performs full USB-C Configuration Channel logic detection for Source (DFP), Sink (UFP), and Dual-Role-Port (DRP) roles, and operates from a 2.85 V to 5.5 V supply across a -40 C to +85 C ambient range, making it a self-contained interface manager for space-constrained consumer and industrial products that need compliant Type-C attach-detach behavior without a dedicated MCU firmware stack .
Typical application scenarios for the FUSB303BTMX center on power-only or low-complexity data-capable Type-C ports where Power Delivery negotiation is not required. It is widely deployed in smartphones, tablets, laptops, mobile accessories, industrial equipment, and power banks as a CC logic front end that reliably detects orientation, current-advertising level (default, 1.5 A, or 3 A), and role attachment .
