I am referring to the AB8500 device data sheet; not sure if its
available open.  I have taken the minimal/maximum figures as what is
mentioned for each supplies.

Yes, if you are referring to regulator enable/disable.

As i said earlier, my intention is to hard code the machine constraints.
The actual control in terms of enable/disable, controlling supply
voltages will happen, as you say when consumers are hooked up.

Thanks,
