If for instance you want to switch 5A in a 12V circuit datashwet you only want to waste 0. It contains an opto-isolator and does all the gate driving. However it has a very low Rdson.

IRF530A Datasheet

Excellent post, was very illuminating! If it is not there, the gate will not get any voltage from the 12 V power source. But if it is working for you, that is good. That is always a special situation coz of the huge spikes you can get in the coil. I will use Arduino to dim the power acording to inputs from handlebar. Very good article, thanks for talking about a subject often overlooked by many.

For the IRF it is even worse. As the can be fed with up to 18 Volt, it datasheeet be a big problem to use the to switch.

Backyard controller design Eric’s Arcana and RiderX. Realise though that it is an inverting circuit. I am not sure where you are based but the IRL costs abt 60 cts where I am. An attiny85 could do that as well. Looking at those graphs one can see that at a gate to source level of 5V Arduino levels the IRF is only capable of delivering 1 Amp, whereas it is specified for 5,6 Amps continuous current.

The IRF can obviously take 4 amps, but sadly it expects a higher voltage on its gate than the most microcontrollers can deliver i presume you will use a microcontroller. Thanks — You are correct. Perhaps it is a lose wire or something. Notify me of new posts via email. To find out more, including how to control cookies, see here: But in reality you dont need that formula as it mainly has to do with the range wherein the FET DrainSource acts as a pure resistor. Using the transistor to drive the gate with higher voltage solved the problem.

Twitter Facebook Email Google. Though that seems like the FET is suitable for an Arduino, I do not think it is an optimal combination.

Normally the impedance of a FET is high enough to not lose any signal over that resistor. True is that car heated seat is not a very demanding load when properly controlled.

Would like to have a non inverting driver, do you have any recommendation how to solve this, or best IC driver for arduino. If the steppermotor adtasheet not draw too much, think about an ULN Whats about this, I have check in the datasheet and seems to work very well at TTL levels even with a lot of Amps.

It is not a true logic level mosfet, it needs some 10 volts. The 2n series, often used with the arduino is even worse in that aspect, but if used to switch an LED it is OK rdsOn about ohms at 4.

I should turn on a load some LED lamps in paralel with a Mosfet. I will try source a IRL I just touched the gate pin to turn motor on. In my schematic I use an output with a small resistor Ohms in series with the gate of the N Channel Mosfet STP3NA and my load is in drain like the first schematic showed in this post, but I have no R1 resistor between gate and source, I only have a resistor like R1 in the second schematic.

Not an ideal choice, but a good one.

Well, you would need to put an inverter before the circuit i provided, either by a logical gate or with yet another transistor. It doesnt look dedicated datasheett a steppermotor though, more to drive a rgular DC motor.

You are limited to a current of about mA. Then you can find the current in the datasheet? Somehow Logic P channel mosfetsarent as plentiful.
