BQ25120A: Determine if battery is connected or disconnected

Mitchell

Part Number: BQ25120A

Hi Team,

On the BQ25120A is there an easy way to determine whether or not a battery pack is connected? For example, consider an application that has a removable battery pack and the user decides to plug in the product to it's charger when the battery is not attached.

Thanks,
Mitchell

Mitchell,

You can look at the BUVLO fault status to see if the battery voltage is higher than BUVLO setting. Note that condition of when protector opened will be need to accomodated. Could you elaborate in detail on what the application needs?

Thanks, Gautham!

BUVLO should be good for now. I'll reach out if there's additional conditions that need to be accounted for.

Best,
Mitchell
