Unfortunately I didt find a good solution to solve this problem.
And thanks raider988 for briliant idea I finaly fix it with his workaround.
I decided to use original MOSFET. 12v connected from capacitor on PCB to AMS1117 and then to ATtiny13a.

ATtiny13a coded with 32 KHz PWM and +DutyCycle 74.4% (I get this data from working Dyson)​...

Hope for your help.
I have got problem "not spinning any brush" with Dyson V10 Animal like [B][URL="https://www.badcaps.net/member/153260-raider988"]raider988[/URL][/B].
Everything works fine, except brushes.
I found in internet a self-made schema of similar VC (not sure it fully correct). I also got V17 from a friend of mine for testing.
What I have done before this topic:
With an oscilloscope I checked what was going on when V10/V17 starts without connected brush.
And I got a same graph pattern on both VCs.
On good V17 pcb starts...
