BQ51003EVM-764: Power transfer through metal

Part Number: BQ51003EVM-764

Is it possible to suppress FOD. Want to transfer through 20um aluminum Transfer stops as soon as metal is inserted.

  • It is possible to turn off FOD feature on TI transmitter side, info is in the data sheet. But should be done with a great deal of caution and not recommended.
    Aluminum will act as a large foreign object and absorb a lot of power resulting in significant thermal rise.
    Power transfer thru aluminum is probably not possible.

    Thanks Bill for the information. My aim is to run the transmitter at full power, i.e. 110KHz and study the effect of metal in between Tx and Rx. I want to operate Tx always at full power instead of power control based on Received power. Transmitter is bq500212A .

    Looking difficult in present scenario but need help to solve it.
