15 W wireless charging with proprietary data transfer

Other Parts Discussed in Thread: BQ51021

Hello,

I am looking into a method to send device ID info across a wireless charging connection.  We are charging at around 15 W (Qi medium power) and so the BQ51021 won't work for us, is there a solution that can allow transmission of data in similar fashion to the BQ51021 but with a higher charging power?

Thank you,

Erik
