Hi,
I am doing a wireless battery charging design using BQ51050B.
I am referring to TIDA-00669 (500mA Wireless Charger BoosterPack with Gauge Reference Design) as the application circuit.
Because I don't want to do the FOD tuning (need extra equipment), can I just use the recommended resistor value for FOD (R15=200, R24=20k), and just change the R14 for the current limiting value?
But from bq51050BEVM-764, the resistor between FOD and RECT becomes 42.2k instead of 20k.
Which one should I follow, if I don't do the FOD tuning?
When I use an off-the-shelf Qi V1.1 TX product for charging (cover to cover contact), does the performance degrade without FOD tuning of my BQ51050B board?
Thank you.
Regards
