Hi Kuo John,

ACDRV and BATDRV would present a break-before-make logic in switching ACPWR and battery. It would turn off/on ACDRV and turn on/off BATDRV to make sure there is no shoot-through risk. How is your system connection? since you don't use BATDRV, I want to make sure the system connection is fine without control ACFET.

Thanks,
Ann Lien

Hi Ann,

In my application, just charger only, not connect system.

Hi Kuo John,

If there is charger only and no ACFET and BATFET on charger side, you don't have to concern the shoot-through risk. You can reserve only one RBFET for blocking reverse current and let surge stopper do the ACFET function.

Thanks,

Ann Lien
