mosfet driver IC + an arduino + solar panel requirements?

Projects General Guidance
1

I have a mosfet driver IC and an arduino that have to be powered from the solar panel I have.

I will get from two pins of the arduino two pins that will go the the mosfet driver IC for high and low side switches.

Now the arduino needs 7-12V as I understood from the datesheet and the mosfet driver needs 15V.

I bought a voltage regulator that will have a fixed output voltage 15V. now is it possible if I can power the arduino through a voltage divider that will insure 7-12V going into it?

and also, it's maybe a stupid question but, let's say I power the arduino from this voltage divider, what limits the current going to the arduino from the voltage regulator? is it how many pins I use or the voltage regulator itself?

You cannot use a voltage divider as a power supply. See here.
