Roman, I am surprised that "you" don't have this info on your
page. I did a search to find some ckts to reference on my page:

http://www.oricomtech.com/robolnk2.htm#Mot2

Of these, the ones I found most compelling were:

http://www.cadvision.com/blanchas/hexfet/h-bridge.htm
http://www.dprg.org/hbridge.html

[the last has a nice little ckt for sensing motor current].

These show a p-chan MOSFET stacked above an n-chan, but
unfortunately many show the drain of the p-chan connected
to +V, rather than the source, so I am wondering what gives.
