Hello
Ben
I am
sure that one of the hardware gurus will be able to clarify things more and
correct me if wrong, but on first looks the circuit in the pdf looks incorrect
to me if all the mosfets are the same. If I remember correctly, the idea of
the H configuration is to have one of the "top" mosfets on one side of the motor
and one of the "bottom" mosfets on the other side on with the other two off and
vice versa for the opposite direction of rotation. As things stand, my
interpretation of the circuit would be that the top control line just switches
the two "top" mosfets and the bottom line just switches the "bottom" mosfets and
there is no complementary action with regards to driving the motor.
Doug.
