So i want to make a rgb led strip setup with irfz44n mosfets. The datasheet says that once 4.5v is applied on the gate the mosfet will start to let through about 9 amps. My psu is only 5 amps. Does this mean i can't dim the colors when using the arduino's analog pins?
EDIT: Sorry for not being clear. I want to power my common anode led strip with a 12v 5a psu. Every color (red, green blue obviously) is connected to his own mosfet's drain, source pin going back to the psu's and arduino's ground. The gate i want to power with an arduinos analog pin. My question now is, will i be able to dim the leds since the gate-to-source picture on the datasheet says at 4.5 volts on the gate the mosfet will start to let 9 amps flowing from drain to source.
