Hi,
I've build a complete solution, Rx and Tx based on ;
Rx : BQ51050B
Tx : BQ50002 + BQ500511
During developpement, I've removed FOD functionnality (Tx side) by linking FOD_THR pin (BQ500511) to 3V3.
Now it's working, how to calibrate FOD ? I've find a GUI for BQ51050 but not relevant because impossible to be mis aligned in my case : my device(Tx) can only charge his battery on my charger (Rx). Coils are always aligned by mechanical design, impossible to be 5mm on left or right.
Thanks for your help, method, to determine resistors needed for FOD_THR value in my case, how to estimate transmitted power, etc....
Best regards
