Hello,

 

I just wana use the pin SMBALRT as a "simple PG" = asseteed if Vout is between POWER_GOOD_ON an OFF.

By reading the datasheet It is not clear if:

-the PG function can operates even if the ADP1055 is "off"?

-witch register is used to configure the function of the SMBALRT?

-is the PG lacthed or not (do I need to clear faults to refresh the PG)?
