    Hi,

    /BATDRV should be controlled by our chip. BQ25703A will control /BATDRV signal condition based on operation mode.

    But if you want to change status of /BATDRV, maybe you can use below register.

    1. ChargeOption0: EN_LEARN bit. If you enable learn then BQ25703A will force turn on /BATDRV to discharge battery

    2. Chargeoption0: CHRG_INHIBIT bit. If you disable charger then BQ25703A will turn off /BATDRV to stop charge battery

    Hope this explanation can clarify your question.

    Thanks
