What i like you to do first is to detach the pic-circuit and just put 5 Volt on the entrance of yr FET circuit, via say that ohm resistor, and see if then your lamp behaves the same. Was that the same as for the mosfet?

Also easier if you need to do high side switching. Thanks — You are correct. Switching speed indeed is important. The only caveat using those AO parts, is their size: It contains an opto-isolator and does all the gate driving. See the reference below: The input capacitance is best chosen as low as possible. See the reference below:. I have chosen to datashret one in just to be sure.

IRF9622 MOSFET. Datasheet pdf. Equivalent

Also the and will idf9622 more efficient with this circuit. Im actualy pondering the same question as Legolas. Notify me of new posts via email. Yes im using Arduino to control the circuit. And a step up boost converter to supply the 5.

Use a baseresistor of say Ohm. You are commenting using your WordPress. But if it is working for you, that is good. Thanks, I learnt few things in my new journey. Maybe you alreadymeasured it but just to make sure, when your problem aises, have you measured if there is still voltage on the gate or even voltage on your PSU?

Sorry, your blog cannot share posts by email.

But to be sure i had a question. Yes you can make it Ohm.

You are commenting using your Facebook account. I am not sure what datasheet you looked at but I do not see a max of 4Volt, I see a max of ca 20 Volt. I had a IRF Mosfet but now i understand why it became very hot. Not an ideal choice, but a good one. I seem to have missed your reply at first since I did not subscribe to your posts fast enough apparently: You are limited to a current of about mA. I am using this converter: Can i use this circuit with Arduino to drive 2 x 20W 1.

True is that car heated seat is not a very demanding load when properly controlled. It doesnt look dedicated to a steppermotor though, more to drive a rgular DC motor. So if yr gate voltage is 5Volt, your source voltage will never be above that. The dissipation then is 5x5x0. Somehow Logic P channel mosfetsarent as plentiful. How can I find the current in the LED? Well what an amazing article. Is it for audio?


That 52 mOhms at 2.

Using MOSFETS with TTL levels (5 Volt and 3.3 Volt)

For a mA current you then need a seriesresistor of 33 Ohm. So, the bottom line is: Thanks, perhaps we are just discussing terminology here.

The transistor may burnt. IRFZ44, and you want to switch somewhat higher voltages i. At 5V volt on the gate, the IRF will pass something around 4. I can imagine that a SOT23 indeed can only take a current the size of 7 amps if there hardly is any dissipation read low RDSon. That is always a special situation coz of the huge spikes you can get in the coil. This actually is used for heatedbed in 3D printers up to A. Another thing to beware of in datasheets is Vthresh threshhold voltage.
