I'm new to small electronincs, but I do have a grasp on the basics of Ohms law...So if I have a 6V motor that pulls 2.4A and will be running off 4AA batteries(about 6v) and I'm going to turn it on with an Arduino Digital Pin, I just need to pick the right mosfet. I've been reading up on them but still find it somewhat confusing.I kind of need a bit of a walkthrough with picking one of these out. I'm on Digikey right now and using the info off of here to try and understand what digikey is asking for and this is what I have so far:
Discrete Semiconductor Products > FETs - Single
Fet type:Mosfet N Channel Metal Oxide type
Fet feature: logic level gate
Vdss 12V(just in case of any spikes in voltage right?)
Current Continuous Drain (Id): 4A(again, motor surge on startups, so going higher for this just to be sure)
Rds On (Max) @ Id, Vgs: Not sure about this one as I know I need 5V to turn it on, but how much resistance do I need?
Vgs(th) (Max) @ Id
Gate Charge (Qg) @ Vgs
Input Capacitance (Ciss) @ Vds
Power - Max: 12W (5*2.4)
Then it's just mounting type and package case
I know this is a lot of stuff to go over so if I can any help at all on any parts of my question here I'd really appreciate it.
