  • Hello Kei,

    PA_GATE_VSYS -Leave Floating
    PA_GATE_VBUS -Leave Floating
    PB_CC1 - tie to GND
    PB_CC2 - tie to GND
    PB_GATE_VSYS-Leave Floating 
    PB_GATE_VBUS -Leave Floating
    PB_VBUS - tie to GND
    VSYS - tie to GND

    Do keep in mind without VSYS TPS65994 can only operate in 5V Source mode.

    Best Regards,

    Christian.
