Hello,
I am creating a stand-alone battery pack for a product using the bq20z65 gas gauge and bq24747 smart charger.
The customer has requested that the battery pack be chargeable when removed from the host system.
The battery pack powers the gas gauge constantly without ever letting it reset, however the smart charger looses power once disconnected from the system until it is given external power.
Is there any way to have the bq24747 remember it's input current register value even if it loses power?
Is there any way to have the bq20z65 gas gauge send the input current command along with the charge voltage and charge current command?
The lack of this ability seems like a glaring oversight for a suite of products designed to make a stand alone battery pack.
