Hi, John,
I did not find any gross error in the schematic. I would suggest 5mmx6mm FET for high power chargers, such as CSD18511Q5A.
We have a 240W reference design online. Please check it out.

Hi Alberto,
Theoretically, there is no power limiting for BQ25730. The charger detects the current through the sense resistor. The smaller the current sense, the higher the power.
However, each component has thermal limiting. When the power level increases…
