Great presentation as always. I am going to subscribe your channel and share it with my other classmates. You are a great teacher and you explain things in a very good manners. Really I like your videos and subject matter is very informative and to the point.Thank you sir.
Hello. In the first place, I would like to thank you for everything that you do on this channel. It is very helpful ! I have a question, and I can't figure it out, please, can you help me :) ? What is the purpose of current in MOSFET drivers? For example TC442X are rated at 6A. Why we need these 6A ? Is it for MOSFET transistors, or for the load (For example if my load needs 6A, besides the fact that MOSFETS need to be rated at 6A, the MOSFET driver has to provide 6A too?).
Part 2 will be uploaded Saturday and part 3 on Sunday. The schematics are at: www.bristolwatch.com/TC4420/index.htm www.bristolwatch.com/TC4420/TC4420hb.htm www.bristolwatch.com/TC4420/TC4420hb2.htm
Part 1 of 3. From simple circuits to applications. Pt. 2 TC4420-29 MOSFET Drivers Circuit Examples ruclips.net/video/-Pmhx_ebJKM/видео.html Pt. 3 TC4420 MOSFET Driver H-Bridge Circuit ruclips.net/video/h_0t50j0BxM/видео.html
I don’t really understand why to use TC4420/TC4429 to drive the high current IRFZ44N MOSFET. Why not just direct pwm pin signal from controller like arduino or esp32? or because it is to drive multiple parallel IRFZ44N MOSFETs? Thanks for the video.
I did not watch all the video. So please bare with me. You was questioning how to run the Fets fully open. Have you thought of using a simple (JOULE THIEF)? This little circuit would do the job with very little power input. What do you think? Wouldn't this work for your circuits?
This was designed for MOSFETs. Driving MOSFETs takes very little power as such, even in parallel. This serves more as an interface circuit. I looked up JOULE THIEF and besides using bipolar transistors this involves some transformer or special inductor. Bipolar transistors are current operated - MOSFETs are voltage operated.
@@LewisLoflin Yes I know what your saying. Thanks for your comment. I was just thinking even though it would take more components, this small circuit would serve you better.
Sorry for the stupid question, but the idea of putting the MOSFETs in parallel is that you can handle N times the current that a single MOSFET can handle?
I assume you are using a microcontroller. On power up the input pin could be floating, so add a pulldown resistor to be safe. I didn't use one and had no problems.
@@LewisLoflin yes am using tl494 circuit with the tc4420 on my half bridge inverter I get some pnp today so tomorrow I will try to fine time to build the circuit
I'm wanting to drive a mosfet with a TC1411N driver chip. because its a fast chip and i really need quick on and off times. was thinking of using a hall sensor to trigger a digital signal into the driver. what are the connections form the driver to the mosfet ? would it be exactly the same as your circuit shown in this video @6:55 ?
What about capacitance? Input capacitance Ciss of the IRFP064N is ~4,000 pF but the TC4429 Capacitive Load Drive Capability is only 10,000 pF. Thank you.
@@LewisLoflin Thank you for the interview. Do you have experience of observing over two or more DRIVERS in parallel? (When they work for a group of MOSFETs using one common PWM source). Thank you.
@@LewisLoflin hello thank you very much for your reply. The pin 2 input is conected to my signal generator. 4 and 5 are common ground, 1 and 8 are common 5 volt dc, 6 and 7 are the output. I'll apreciate your help
@@LewisLoflin hi it's working fine thank you. This low amplitude -1.3v to - 2.3v i didn't notice earlier i though it wa 0 volt. My best regard. Nice tutorial
It was a useful and educational video. I watched with pleasure.
Good to have you back.

Thanks, man! Love your videos! :)
Great stuff. Super helpful as always! Not watch part two and three yet. Could you cover even higher power systems like 50A?

On some MOSFETs the drive voltage is not high enough and is worse with IGBTs.

But arduino dont put out high voltage to turn the the chips so how the pwm work with this chip can u explain how the pwm connect to the chip
Sorry for the stupid question, but the idea of putting the MOSFETs in parallel is that you can handle N times the current that a single MOSFET can handle?
Not stupid. Yes.
So I don’t need a pull down resistor the Ic does the pull down is that current

This should work.
@@LewisLoflin okay, thanks ya !
Hello. Thank you for the videos. Question: Is the TC4429 capable of driving three of IRFP064N in parallel? Thank you.
I'm sure it will.
@@LewisLoflin Many thanks
What about capacitance? Input capacitance Ciss of the IRFP064N is ~4,000 pF but the TC4429 Capacitive Load Drive Capability is only 10,000 pF. Thank you.
@@ruslanhajiyev The TC4429 will drive 6A peak so low a low values input gate resistor could limit this but slows down switching speed.
@@LewisLoflin Thank you for the interview. Do you have experience of observing over two or more DRIVERS in parallel? (When they work for a group of MOSFETs using one common PWM source). Thank you.
Hello i got the tc4420 and i can't get low signal output but only high signal output on my oscilloscope from pin 6 and 7. Someone can help ?
I have to know how it is connected. What is +Vcc? What is the input connected to?
@@LewisLoflin hello thank you very much for your reply.
The pin 2 input is conected to my signal generator. 4 and 5 are common ground, 1 and 8 are common 5 volt dc, 6 and 7 are the output. I'll apreciate your help
@@dougboyao5839 What is the level of the signal generator? Also your supply voltage is low. Try a 12-volt supply and a 5-volt square wave input.
@@LewisLoflin hi it's working fine thank you. This low amplitude -1.3v to - 2.3v i didn't notice earlier i though it wa 0 volt.
My best regard. Nice tutorial
@@dougboyao5839 Great!
