bq28550 CEDVs calculation and Hibernate Mode

Other Parts Discussed in Thread: BQ27541-V200

Is it need to calculate EDV factor even if a customer doesn't use CEDV function?

Doesn't bq28550 have Hibernate Mode problem like occurring on bq27541-v200?

Hibernate Mode problem: If using Hibernate mode in I2C, wrong voltage and temperature readings may be seen upon waking from Hibernate.

If simply using EDV mode, then you don't need to determine the CEDV coefficients. You will still need to enter EDV2, EDV1, and EDV0. EDV2 is the voltage at which there is 7% remaining capacity. EDV1 corresponds to 3% and EDV0 correspond to 0%.

As for the Hibernate Mode problem, I don't know for sure. Somebody will look into it, but it will likely be next week before someone is available to check it out.
