Your Question:
Hi. I want to know how to wire up a mosfet so I can use pwm, and on another circuit an op amp to control the current flowing throught MOSFET. Here are the things I do not understand. 1) Do you have to put pull up resistors on p channerl and n channel mosfets? If so how do you calculate the ohmic value of the resister? 2)How do you calculate the resistor for the gate of the mosfet? 3) I have p channels IRF9530 which I want to pulse to control an electric motor. The supply is 72volts. How would I calculate the Pull up resistor and the gate resistor. Please try not to use too much datasheet terminology as I have huge gaping holes in my knowledge of electronics. ALl the best Barry
