Tool/software:

I'm curious about how the MPPT works for BQ25792EVM.
I would appreciate it if you could let me know whether you use "constant voltage control method" or "P&O method"...

Hi Yeongjun,

You can write software to implement fractional open circuit MPP. You could use similar logic as was used to implement this with BQ25895 at the link below:

Alternatively, you can switch to pin2pin and reg2reg BQ25798 which has a fractional open circuit MPP algorithm that can be turned on via I2C.

Regards,

Jeff
