Hello actionplus,
what you can do, is hook up your 648A chip... pin B3 is your PWM...
put about 20 k resistor from B3 to ground, and have that same pin to go the gate of the Mosfet...Then connect up your Mosfet drain to a 20+k resistor to positive (load for it) and put your motor in parallel with this resistor.
It should work like a charm...I will try to workup a schematic if you want.
