Cirrussport is an unknown quantity at this point
Re: victor 885 parts

So basically I need to look at whatever voltage is usually needed on the low side to turn on the mosfet. then take the supply voltage and increase it by this number to run the gate.

For example.
If it takes 8v to turn on the mosfet on the low side.
And my source voltage is 18v

Then i need to run the upper gates with the sum of those voltages.

Required gate voltage(top side) = supply voltage + Required gate voltage(bottom side).

And that ic that was mention is im guessing used to help create this extra voltage?

I think i got it but i may be totally wrong.

Thanks
