All n type bridge vs n and p type. #115

Closed alnaufra closed 7 years ago

alnaufra commented 8 years ago

Hi, You say that cheap esc have p type fets in the hight side and n type on the low side, and that an improvemnt to that is a all n type bridge. I don't see why, could you explain me why all n type mosfets is better? From my point of view(I'm doing an esc with arduino) it's easier the first way and i can't see the down side. Thanks in advance.

try to find a 100A p-Fet for under 30$ - if there is one at all. n-fet supports much more current than p and costs <1$ for 100A, but requires a special driver if you want to use it on the high side.

OK! so is just price based for hight current. Perfect thanks a lot for the fast reply!
