Part Number: BQ24770
Other Parts Discussed in Thread: BQ2477

Hi

Some question for BQ24770 battery charge controller.

We try to monitor the system power from PMON.

It seems the AC mode function ok.

The DC mode have some trouble.

We lost the PMON data from EC to read BQ24770 via SMBus.

 Follow picture for you reference.

 AC mode (The adapter plugin + battery)

The DC mode (The Battery only)
