PF1550 power input question?

Hi, 

     I am looking to use the PF1550 PMIC with an iMX6UUL micro and wondering

about the power path capabilities of this part. The datasheet lists

VBUSIN to VSYS resistance  as 100 250 550 mΩ. I am trying to understand if

the only current limitation is maximum case temperature? The reason I am questioning

this is that I see only 1 VBUSIN pin and there are 2 VSYS pins  to drive the power

input of the part's regulators. I want to use the PF1550 PMIC with and without lithium ion

battery pack in multiple applications.

 

Thanks!

Larry
