    Hello,
    It can't be left floating, it is used to detect a USB connection, you have to connect this terminal to VBUS through the voltage divider specified in the datasheet.
    If the upstream VBUS is going to be always on, then you can connect this terminal to 5V using the voltage divider specified in the datasheet.
