BQ40Z80: MAC Shutdown() Command during charger is connected

Part Number: BQ40Z80

Hi Team~

If shutdown() command issued during charge mode , it seems to be a slight malfunction.

This is expected to be because voltage is applied to the Vpack terminal.

-. SDM = 1

-. CHG,DSG fet turn to Off

-. But BQ40z80 is still alive

I would like to know whether charging voltage is applied to exclude the shutdown command.

    Hello Sangsoo,

    They shutdown command should not be issued while in charge mode, normally shutdown mode is only entered during initial shipment of the battery or long terms of storage, ii should never be snet while in an active mode.

    Sincerely,
