I want to control a DC motor using a P-channel MOSFET.
I tried the motor with a 5VDC power supply. It works perfectly and speeds up in no time. I measured the current flowing through, it's around 0.15 A.
Now, I wanted to include a MOSFET. I used FQP12P20. I connected the source to +5V, the gate to GND, and the drain to the same motor. The motor still works, but it takes seconds to speed up. The current flowing through and the voltage on the motor is the same. What could be the problem?
