I'm pulsing an IR led at 1 A with PWM for a short period of time. To do this I use an N-channel (power) mosfet
At the moment I use the setup in figure A, but I was wondering if the setup in figure B suffices. My train of thought: a gate doesn't draw any current, right? So no delimiting resistor is necessary. And since the Arduino already pulls down the gate nicely to ground, I don't need the pulldown resistor as well. Is this correct ?
