Hi Team,

Would you please confirm during ACOV event, BQ25606 can still provide system power by battery through BATFET?

Thanks.

Hi Allan,

Yes, the battery can still power the system during ACOV.

In the waveform below, I increased VBUS from 5 V up to 15 V in order to enter ACOV. Even though the converter stops switching, VSYS does not fall to zero because it is still powered by VBAT.

Best regards,

Angelo
