Mamba Max FET Datasheet

[BrianG]

I took my MM apart and was able to determine the part number of the FETs for those interested. If you flip it over, you can just make out the part number on a couple of the FETs: 22N03S.

And here is the datasheet...

I haven't had time to really pore through it, but I'm sure other electrically-minded people will like this (GriffinRU, Zeropointbug, etc).

my brain just a 'sploded

LOL. I just noticed that the Quark and MM use the same FETs! So any problems with heat, blowing up, etc is purely programming! VERY interesting!

Why's that?

okay, a good 70W on 60 C. How many are there in there?

[BrianG]

Um, I forgot to count them. I got too excited when I was able to get the part number. Oops :dft001:

I think there are the same number on the bottom as on the top. IIRC 6 in a row X 3 rows (for each phase) X top and bottom. Someone with a MM in front of them can confirm the top count (at work right now).

[zeropointbug]

yah! As soon as I saw the 22N03S I was like whow... :eek:

It must be a good FET then, if both are using it, two of the best controllers out (not that there are many for cars).

So you mean both the Quark and the MM have to same amount of the same FET?

This is kinda cool, in a way.

[crazyjr]

So technically they are the same except programming, and packaging. If I'm right about that, then 5s is doing no more damage to the MM than the Quark

[zeropointbug]

Or the caps... caps should be twice the voltage rating of the max 'specs', IMO.

[crazyjr]

if i'm correct the quark has 25V caps but i think it has 4, with the mamba having three 25Vcaps, they should be about close

[zeropointbug]

Actually, the Quark only has two. :002:

If i ever used my Quark without the case, I would solder new caps that are 35v, and larger uF cap. You can't use the case though, they would be too big.

What IS the issue with the Quark with 6s? Was it the caps? Or the FET's?

[zeropointbug]

Wait, I just checked, the Quark has two 35v caps, 330uF a piece. They might have a temporary rating of 40 volts.

[crazyjr]

Ok stand corrected, thought i read somewhere they were 25V

[Serum]

It makes no sense in comparing the quark and the MM because they use the same fetts.

The entire setup may be completely, i mean COMPLETELY different. they may work with another switching frequency, another startup sequence, other software, other steering technique etcetcetcetc.. a powerfet is only a small detail of an entire controller.

[BrianG]

Very true Serum. It's like saying two cars are the same if they use the same piston.

We already know they behave differently, so the programming is obviously different. The Quark is much smoother, but heats up more than the MM. The Quark also seems like it has beefier traces and stouter construction. Don't get me wrong, the MM is a nice controller (especially for the money), but I still like the Quark better for larger vehicles. And let's not forget that the Quark can run pretty much any motor. The MM tries to cram as much circuitry as possible is a smaller area so thermal concentration will be higher.

Personally, the Quark would be THE controller if it had a better heatsink (or maybe just get rid of those stupid thermal pads), computer programming function, and lower price.
