BQ34110: DRD Warning Counts after power loss ?

Pial

Part Number: BQ34110

Dear team,

Would you be able to help me with below questions ? Thanks a lot!

In a system where the GasGauge sometimes loses power. Will "DRD Warning Counts = 3" still work as described in the Reference Manual or will the history of DRD warning calculations be forgotten at every power cut?

Best regards,

Hello Pial,

The DRD Warning counts is saved in DataFlash so it would be remembered after a power loss, but if the power loss happens before an event is stored in DataFlash then the data could be lost.

Hello,

So I contacted the design team to confirm that DRD cycle counts was stored in DF, but they informed me DRD cycle counts are stored in RAM so the information will be lost.

Sorry for the confusion, I hope this helps!

Sincerely,
