    Hi Wen,

    If not used, then I suggest connecting D+=D-. This sets the input current limit to the LOWER of the value set per the ILIM resistor (if enabled in I2C) in standalone mode (no watchdog ping) or the value per the I2C ILIM register when in I2C mode (watchdog is being pinged or disabled).
