Part Number: BQ25756

Tool/software:

Hello,

I would like to know what would happen if I activate the MPPT and use a "normal" and continuous power supply. I´m going to see any output here or would it just not work?

Thank you!

    Hello Nerea,

    In MPPT mode with a normal power supply, the BQ25756 will first sweep across VAC_DPM values to find the maximum power point of the input supply. After that, the BQ25756 will output a normal charge current.

    Let me know if you have any questions about this.

    By the way, the BQ25756 FAQ page has a few notes on this that may be helpful.

    Best Regards,
    Ethan Galloway
