FUSB303EVBUM FUSB303 Evaluation Board User s Manual Introduction The FUSB303 evaluation board and included software allows www.onsemi.com customers a complete platform to evaluate the TypeC interface detection solution the FUSB303 provides. The evaluation board is EVAL BOARD USERS MANUAL designed for both standalone operation and connection to test equipment for specific testing requirements. With a single connection to a PC and using the FUSB303 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 FUSB303 device is a fully autonomous USB TypeC controller optimized for 15W or less applications. The FUSB303 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 USBC specifications. The FUSB303 features 2 configurable I C address to support multiple ports per system or it can operate autonomously configured by just pins. The FUSB303 features ultralow power during operation and an ultrathin, 12 Lead QFN package.

Evaluation Board Layout TypeC Signal Connections APPLICATIONS INFORMATION The FUSB303 evaluation board allows different ways of Power Configuration connecting to another TypeC device or controlling the The FUSB303 evaluation board is designed to be powered signals of the TypeC receptacle based on the type of from just the PC connection or powered externally based on testing that is required. testing requirements. CC Pins Power Supplied From Board The TypeC CC1 and CC2 pins are directly connected The FUSB303 can fully operate from the VBUS input of to the TypeC receptacle, J1, on the board. There is also the microB USB receptacle J2. To operate the evaluation a test point for each pin that can be used to connect the CC board, the USB power should be provided to the board over pins externally. Note that the FUSB303 evaluation board the microB USB connector. Then, the onboard regulator contains the minimum cReceiver capacitance specified in generates VDD, which is 3.3V for the device supply. Once the USB PD specification for the CC pins which is 200pF. valid USB power is provided, the indicator LED, PWR, This capacitance is C8 and C9 in the schematic. will be turned on.
