Hello guys!!!
I want to ask 2 - 3 thingies this time...
Firstly... With a N channel... Is it better to feed the gate through 13V battery, or with 5V regulated...
And secondly...
Since I deal with currents rated at 20A.... When it's better.... When I feed the gate with 13V or 5V???
The power source is at 12.6V ~ 13V... A Lipo battery...
And thirdly... As heatsink.... is unavoidable.... and I cannot unfortunately place more MOSFETs as the place is tight and I don't want to
have problems with the current sensor I'm testing.... Not sure If I have anyways.... whatever...
How can I calc the heatsink dimensions???
I use the IRF540 rated at 175 oC max temp.
Thanks in advance!
