Who can tell me what should I improve i my schematic? If for instance you want to switch 5A in a 12V circuit and you only want krf1405 waste 0. At 5 Volt GS it can however only take some 4.

As the can be fed with up to 18 Volt, it shouldnt be datasgeet big problem to use the to switch. Yes you can make it Ohm. The power FETs are the most expensive parts. Would be interested to hear how the FET holds out on 8 Amps. Was that the same as for the mosfet? Switching speed indeed is important.

That indeed is odd and I start to wonder if it is the IRL that is shutting down or something datasheft. Thanks, perhaps we are just discussing terminology here. Jon likes these hall-effect sensors over shunt resistors: Thanks Adriaan, Though technically it is a voltage divider, that is not really the function of it.

Indeed, more and more FETs availablefor 3. So we’ve pretty much settled on the “open source motor controller” design.

More and more cheap Mosfets. Is it for audio? If bought per 20 it is 26 eurocts a piece. The 20 Volt you probably saw dtasheet the datasheet, but datashest is the max voltage on the gate. That is definitely enough for most applications. Post was not sent – check your email addresses!

The driver will have only 2 inputs, allowing off, fw, rev and brake. We need 8 per board, and two boards per orb, so they add up fast. They indeed can stand almost 7A, but only when sufficiently on or off. Perhaps it is a lose wire or something. Is it possible to use two or maybe ddatasheet IRF to handle more amperage?

I am using this converter: Well what an amazing article. Navigation menu Personal tools Log in. I am not sure what voltage you need but you may try this one a 30n Some people however have trouble reading a datasheet or do not know what to look for and in that case foing with TTL level FETs is a safe option.

R1 is just there to limit the current through the gat, coming from a microcontroller pin. The datasheet indicates max Vgs 4V but the curve shows that at 5V the mosfet can deliver current way above my requirement Thank you for your help.

The STP3NA I do not know very well and I couldnt quickly find a readable datasheet, but though it doesnt seem to be a Logic level FET, from what I could see, it should open enough around 3 volt already… but if you have a better datasheet, please check that.

Same specs but logic level is what I’d recommend, but I sorta doubt there is such a beast. Mar 31, 2. I am not sure if there is an easier way to do it. This is for direct transfer so it is already mirrorred the right way.

And as i understand when you put 5 volt on the gate, the output on the source i presume is only 5Volt. It has a pretty hefty gate charge, so you won’t want to be turning it on and off very frequently. Backyard controller design Eric’s Arcana and RiderX.

Notify me of new posts via email. Thank you for this very good explanation. That is always datasheett special situation coz of the huge spikes you can get in the coil. The relatively cheap BUZ11 datashee also an option. Command and Control System. Also, if you have the gate floating, the state of the mosfet could be undefined. I guess what you really need to pay attention to is Rds on at 7V, and the datasheet will usually divulge that. OK I try again: Hello — Great post!
