Hi, can i measure the bus voltage connecting the VBUS pin directly to the positive of the voltage source, when i have the INA226 connected on low side?

Michael,
Thanks for using the E2E forums.
Yes, regardless of whether you use high or low-side configuration for the INA226, the VBUS pin should be connected to the positive of the voltage source of the load circuit being measured.
This older post walks through a great example of getting a system up and running. Let me know if you have any additional questions
