BQ24171: How to detect the adapter is not presented

Part Number: BQ24171

Tool/software:

Hi team,

How could we know if the adapter is removed from the charger if the system CPU needs to know?

Can I use BATDRV pin to drive the MOSFET and give the high/low status to CPU at the same time?

Is BATDRV pin pulling high only when the adapter is removed (Battery discharge)?

Thanks,

Leo
