Error in the floating gate driver at 5:52, the lamp is always off

Thanks fiŕst.sir is it possible that we can isolate drive circuit from mosfet,because when mosfet damaged or shorted(usually we face in repairing circuits) it damages drive ic .can it be seprated through capacitor or by other means?.thanks.secòndly what is best trap for overvoltage zener(sometimes it get open and circuit damages) or crowbar or any suitable provision.thanks

what transistor can i use for pushpull driver for esp32 with 3.3v logic level

Question the high side switching is very difficult to drive with high voltage of the voltage is 160vdc to the higher side mosfets the gate can handle voltage higher the 20volt so how can the gate get change higher then the supply voltage of 160v to work explain this I use driver transformer to drive the low side switching but the mosfet get hot at 20v to get still this how can I drive 160vdc in a high switching or it’s not possible

The circuit at 1:50 works well with me using IRZ44N MOSFET and supplying a PWM from the Arduino.

Is a Mosfet like a Masserati?

I'm so confused. I bought a logic level N channel FET and it drives from the Arduino when connected to 5v VCC. For some reason my pin outputs, no matter what digital pin I use, don't output enough voltage (or current) to keep the thing on. I checked my code is set to PINMODE output so I don't know what else to do.

Possibly pulls too much amperage from Arduino pin, or possibly not enough. A resistor between the two could help. It could limit the amperage from the Arduino to protect it, and could pull a little more in the case where FET needs a certain current to activate instead of just voltage level.

@@jonathancrowder3424 Thanks. I changed the FET to an older one I had which I thought was knackered, and it works much better. It's weird because they both have the same info on the data sheet about the logic level and vcc that drives it. It's not perfect, and adding a resistor is a must now, where before it didn't seem to do anything. I now have a new problem though.... when the motor's torque is under strain (like if you force against it) the Arduino resets. I've added a diode and a 10mf cap to the motor which seemed to help give it more oomf, but every time the motor stalls it resets the Arduino.

Sa démonstration est très intéressante et très bien faite mais il nous agace avec son accent auvergnat, le gugusse ! On ne dit pas : "moche Fête" mais on dit : "MOS FET". Même chose pour le : "pouche poul".
