And this one doesnt stop too, but it have best voltage and amps propably

The first page of the datasheet says the minimum supply voltage is 2.5V.
There are also an application circuits for higher currents, using external (bipolar) transistors.

>Slower gate discharge?
Charging too.

>Don't know of any of those ICs.
You could just google "mosfet driver". There are plenty of those, from several manufacturers.

Pic related is one popular way to drive high-side N-fets. In your case VCC would be 40V and the D1 supply would come from a 12V (or so) supply instead of VCC. There are also ICs using the same basic idea, except that they are faster.
Another option would be to use a fully floating power supply for gate driver.
