BQ25756: Doubt regarding driver strength BQ25756

Part Number: BQ25756

Tool/software:

Hello i was looking the different registers of the BQ25756 and i noticed one of them is used to configure the driver streng of the Buck-Boost FETs the register i am talking about is in the attached picture. My question is what is precisely this driver strength and why would i choose one configuration over the others.
Thanks in advance.
Juan.

    Hello Juan,

    I would recommend using choosing the highest driver strength (the default) for now. You can choose a lower drive strength to prevent overshoot or to possibly reduce EMI from switching noise.
