[...]ah the schematic *url=http://desmond.imageshack.us/Himg690...ng&res=landing*[...]any thoughts ? :S
the zeners are for getting the vgs or vsg for p and n fets 12 and lower not greater
so you suggest me lowering the resistance connecting collector of bc547 and gate of PFET ??
about the post your talking about i really cant find it :S :S
so if you think the design is ok but resistance values aint how can i determine their values ?
but 1 thing isnot 20v for vgs or vsg is too critical (i mean is too high ? as its the maximum value )
im asking this design is only allowing rotation in 2 direction
and no braking available as shoot through may happen
what about the getting upper side ground of bc547 changed into inputs ??or im missing something obvious?
In1 In2 M1 M2 0 0 ? ? 1 0 ? ? 0 1 ? ? 1 1 ? ?
(1-0) move in 1 direction ( 1,0)(0-1) other direction (0,1)(1-1) Break for me it was low side braking but does it make a difference if its high side or low side braking ?(0 -0 )would be all transistors off
Why is connecting an input to the emitter of BC547 is wrong can you please clarify this ?
