BQ50002EVM-607: FOD Issue

Part Number: BQ50002EVM-607

Hi, Team,

We found the FOD function doesn't work on the BQ50002AEVM. Is there any other setting for FOD function?

    The test you are showing is a metal object on the TX with no RX present and power transfer not started. In this test the TX will remain in standby and only send a low power ping to check for RX, no power transfer will start. LED D1 only indicated power is applied to the board.
    BQ50002A / 511A does not use and FOD Ping to check for foreign objects before power transfer starts.
    After power transfer starts the it will use power accounting to identify a foreign object.
    FOD is part of WPC requirements and the EVM has been certified and meets requirements.
