Tool/software:

Hi,

I´m using the BQ25750 with it´s EVM.

My problem is, that in bqStudio the charging current is quite lower than configured in ITERM, but CHARGE_STAT keeps in Taper Charge (CV mode). What could be the problem?

Best regards,

Achim

Hello Achim,

I have a few questions about this:

What current is ITERM set to?

If ITERM is less than 2A, do you have EN_PFM=0?

Also, can you send the register logs of the charger or a screenshot of the registers in BQStudio?

Best Regards,
Ethan Galloway

Hi Ethan,

clearing the EN_PFM bit solved the problem! Thanks!
