    Hi Johny, 

    Thank you for reaching out!

     You can implement a system power path on the BQ24600 with some extra circuitry. Meanwhile, the BQ24610 has a dedicated pin for BATDRV, which is the battery-to-system MOSFET driver output. 

    If you would like to implement on the BQ24600, I highly recommend following the BQ24600 EVM.  See schematics below for VSYS connections/circuitry.
