    Hi Vinith,

        Yes, if SYS is connected to source of BATFET, this means correct orientation of the output path and there should be no issue. Nothing needs to be connected to SYS for normal operation.

    If you have an EVM, you can verify that when not connecting anything to SYS, battery can still charge.
