BQ25611D: Can we set BATFET_DLY for 0 when we want to enter ship mode with adapter

Leo Yang

Part Number: BQ25611D

Hi team,

My customer want to enter ship mode immediately with adapter when it set 0x07 to 0x64.

And the charger will reboot but it enters the ship mode with 0x6c.

It seems that they can't set the delay time "0" with adapter. But it enters ship mode with delay time bit 0 without adapter.

Could you help this?

Thanks,

Leo

    Hello Leo,

    Please see Section 9.3.7.1 of the datasheet:

    "To extend battery life and minimize power when the system is powered off during system idle, shipping, or storage, the device turns off BATFET so that the system voltage is floating to minimize the battery leakage current. When the host sets the BATFET_DIS bit, the charger can turn off the BATFET immediately or delay by tBATFET_DLY as configured by the BATFET_DLY bit. To set the device into ship mode with the adapter present, the host has to first set BATFET_RST_VBUS to 1 and then BATFET_DIS to 1. The charger will turn off the BATFET (no charging, no supplement) while the adapter is still attached. When the adapter is removed, the charger will enter ship mode."

    Please set BATFET_DLY, then BATFET_RST_VBUS to 1, then BATFET_DIS.

    Regards,
