UCS81003 Evaluation Board (ADM00561)

The UCS81003 Evaluation Board provides the ability to evaluate the features of the UCS81003 Automotive USB Port Power Controller with Charger Emulation. The board allows the UCS81003 to be tested in different configurations by populating jumpers on specific header locations. The Evaluation Board contains the MCP2221 USB to I2C bridge, which allows communication via USB between the UCS81003 and the Graphical User Interface (GUI) running on the PC. The GUI gives read/write access to all UCS81003 registers and has advanced evaluation features like:
• real time register monitoring
• graphical display of current and charge delivered to the attached portable device
• easy interface for custom charging emulation configuration registers
• the ability to save and load register configuration
• a demo routine that shows an external controller logic to apply custom emulation profiles and optimize charging current


    • Configuration of the UCS81003 through jumpers on specific header locations (selection of Active Mode, SMBus address, current limit, communication mode, supply path)
    • The Graphical User Interface running on PC allows advanced configuration and monitoring of UCS81003 registers
    • Test points for monitoring the handshakes on USB data lines (DP, DM)
    • LEDs that turn on when a portable device is attached, the alert signal is active and when I2C and USB communication occurs with the MCP2221 USB to I2C bridge
    • 5V supply path selection: from external AC-DC 5V 3A wall adapter or from the USB host (if it has the current capability), supply paths of UCS81003 (Vs and VDD) tied together or separated
    • USB 2.0 and USB 3.0 compatible (the evaluation board supports USB 3.0 data pass-through)
