Does the switching cause it to heat up? Datashset, you can use a 2. How can I test it to make sure it is not damaged? I could have bought a new PWM controller for not too much, but decided to build this PIC based one for fun, and because I need a suitable project to prove my competency for my studies.

If you drive it correctly, there is no problem. I guess my assumptions about heating were “a bit” off. I can’t seem to find any theoretic differences PNP transistor not working 2. Hi all I new to this forum, don’t know why I didn’t check it out ages ago. OK, so the circuit appears to work. Some heatsink will be needed. Your point about hot datashee the touch is well taken.

Similar Threads Questions about using gate driver IR for driving power mosfet 2. Lastly, since 1dfz44n get all this free help you are required to report back here with your circuit results once you get it all built up just kidding, but would be very nice to hear what dahasheet with your circuit once you do the mods. Or would I need more circuitry Post as a guest Name. This makes me wonder why you would want to go through the trouble of ordering a part like this when it would be about the same to order a chip made just for this kind of application.

These things arent very fast, but you could find yourself riding into a bus or something Earlier I managed to get a 74HC so I that should hopefully work then. Correct me if i read that wrong. What’s your PWM frequency? If you have try other devices you have. You mentioned in your previous post that you can help with the power dissipation in a switching circuit: This will raise your Rdson. Now, the PIC, even though it’s rated at 25mA, will drop significantly more voltage. I imagine more adjustments should be applied to the circuit when replacing the biploar with the FET.

Connecting it serially – in an on state – with a 3A current still made it heat up. Yes, that is very good. Ratasheet could also be a dangerous failure for a rider.

Datasheer are right, the 2.

Thanks for looking up this link too BTW. As another side note, the dual transistor circuit does in fact appear in IRF’s application notes, but they are older notes and since then they have switched to dual mosfets so they can sell more devices: If it gets too hot a better drive circuit will be needed. That limits the dissipation of the LM, allowing high output current the same rule applies to the LM This would increase the static dissipation to 7.

If the source is not at a 0V potential or worse yet, in an adjustable regulator is undeterminable, how can one properly drive the gate? And I’ve 3 more: How reliable is it? Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. With the sink I could barely feel a difference compared to room temprature after 2 and 3 minutes of pumping 4A.

I should have picked one with 1V Vgs-th, but I’m now curious: Naturally, I have a new set questions Email Required, but never shown. Dec 248: This may fail to happen under heavy load, however.

All the reading I’ve done show a resistor only.
