BQ24770: Back-to-Back N-Mosfets

Part Number: BQ24770

Tool/software:

Hi guys.

I am designing a battery charger. The charger is going to be connected to a USB-C port that should be deliver the enough voltage and current depending on how many batteries I am connecting (1S - 4S). I am using the STUSB4500 PD Sink controller for the USB-C connection. The circuit has already a back-to-back P-Mosfets to block reverse current. If I use the BQ24770, do I need to use the back-to-back N-Mosfets
