I need to drive about 1.5A at 5v at PWM frequency for an Arduino. I'm having a bit of a hard time figuring out what mosfet I want. This is what I've come up with so far. The Rds(on) seems low enough to keep my dissipation at only a few mW and it seems to be able to sink the current I need it to but I have a few questions...
Is the threshold voltage what voltage is required to saturate it? Since it has a 1.8 threshold, do I need to limit the voltage to 1.8? Can I drive the mostfet directly from my arduino?
What spec decides whether or not I can PWM with it?
If this one is no good for what I want, could someone suggest a better part and explain why?
Thanks
