Hello Patrick,

Very easy to use are the MC33033 or MC33035.

I used them succesfully in a couple of designs. For the FET's I Used the FDS8958 (Farnell), N- and P- FET in one housing.

For the input use the Hpwm combined with a resistor and a capacitor. (Speed control)

For the feedback just use the signals from the hall sensors who are availble on the MC330XX chip.
Greetings
Paul
