FUSB303B Evaluation Board
User's Manual
FUSB303BGEVBUM
Introduction
The FUSB303B evaluation board and included software allows
customers a complete platform to evaluate the Type−Ct interface
detection solution the FUSB303B provides. The evaluation board is
designed for both stand−alone operation and connection to test
equipment for specific testing requirements. With a single connection
to a PC and using the FUSB303B GUI (Graphical User Interface), or
with just a power supply, the evaluation board can be configured and
function as a Source, Sink, or DRP device with Accessory detection
support.
Description
The FUSB303B device is a fully autonomous USB Type−Ct
controller optimized for 15 W or less applications. The FUSB303B
offers CC logic detection for Source Port role, Sink Port role, DRP
Port role, and accessory detection support, as well as Dead Battery
support as defined in USB−C specifications. The FUSB303B features

configurable I
C address to support multiple ports per system or it can
operate autonomously configured by just pins. The FUSB303B
features ultra−low power during operation and an ultra−thin, 12 Lead
QFN package.
