Hi Kailun,

For the first application, the power requirements are too large for any of our chargers with integrated FETs but we have some charge controllers with external FETs that could work. BQ25750 or BQ25731 may be good options to look at. As for your second application, I'd recommend BQ25798. I'll loop in the PD controller team to see if they can provide you recommendations on a controller to pair with your choice of charger.

Best Regards,

Austin
