Im really appreciate your help.

Hi bilal could you please send me this schematic? I had done schematic for ir2112 mosfet high side voltage ir2112 mosfet as i vary for HIN 0v or 5v two get the same result so i want to know the schematic for real circuit with load. Its design is optimized for use in video camera loading motors.


Low Supply Current: at 3. If you're having this much trouble then I strongly suggest you switch to a simpler project and learn to crawl and walk before trying to do the iron-man tiathalon. Personally I've never used them So the general idea is that to turn a N-channel mosfet ir2112 mosfet, you need to put a positive voltage on the gate.

Ignoring some of the finer details - the higher the voltage you can ir2112 mosfet on the gate, the lower the resistance of the mosfet. Obviously check the data sheet for the max gate voltage Vgs.

The time now is Mosfet Driver to drive high and low side mosfet 1. Today, there are a lot of integrated chips that do necessary adjustments for proper transistor driving. Today, there are a lot of integrated chips that do necessary adjustments for proper transistor ir2112 mosfet. I am curious though as to why you want high-side drive. Why not low-side drive? Are you building a bridge circuit?


You may also want to use soft-start for the motor to reduce starting current. First of all, thanks for your great help and advice. Since the starter is manufacture connected to the ground, and p-mostet will not be able to handle such a large current to drive the motor to drive, that is why I am trying to make this ir2112 mosfet mosfet to be connected to the motor to drive properly. But can I know the near current of gate for each mosfet. So that I will start to use the current limiting circuits for it.

Hi Tahmid. I need to use the IR as a single high-voltage high-side driver Fig 9but i didn't understand how to connect LO to ir2112 mosfet.

Can i make a short circuit or i need to use a resistor? If i need a resistor, what value ir2112 mosfet be good? Congratulations it's a very instructive page.

It's not necessary to use a resistor. You can just short it to ground.

Thank you very much. The reason which you explained ir2112 mosfet this connection is not clear to me. Can you please elaborate it further? Both should then be shorted since the IR ir2112 mosfet a non-isolated driver. I hope that clears your doubt. I will implement it on hardware. Thank You very much.


But its not working. So what should I exactly do??
