BQ24125: Charge a 3S Lithium Ion battery pack

Part Number: BQ24125

Hi Team,

I want to use the BQ24125 to charge a 3S Lithium Ion battery pack. The datasheet doesn't really talk about charging with a 3S pack in detail, but it does talk a little bit about the Feedback pin. Do I just need to set the FB pin equal to 2.1V with a voltage divider on the battery pack?

Beat Regards,
Tom Liu
