Logic level mosfet for Prop 3v3?

T Chap

I know there are lots of posts on this but the search is dead. Is there a known LL mosfet that will sink 5amps directly driven off a Prop?

The IRF3708 is a TO220 or TO262 pack and definitely does well at 3.3V drive sinking. Rds(on) is 12milliohm and it will handle 62A @30V.

I am also using some FDS6990A dual N-MOSFETs in an 8-pin SOIC pack and they are excellent and will handle 7.5A continuous plus you can always parallel them.

I'm not sure what "LL" stands for. (Logic level?) But I know the IRF3708 works well with the Propeller.

Great, thanks guys. I will order some to test out. The dual sounds ideal for the project. FDS6990ACT-ND $1.08, not bad for two switches.

Tayda has good prices on mosfets and
carries a good selection. The price is right
on them too.
