Help me for making H-Bridge motor

Can someone help me, i just want to make sure this one is H-Bridge motor sheet, not for a firework.


And someone can tell me why if i search h-bridge motor in google, there is some sheet using diode between source mosfet pin and drain mosfet pin? like this one
aAp3H

They are probably for protection from back EMF when the motor is stopped suddenly.

Unless you are doing this for education/amusement it would be easier and cheaper to use an H bridge IC.

That's for MOSFETs with insufficient (slow/weak) body diodes.

I cannot say it will work, I cannot say it will not work, there is no indication of load current and voltage. Take a look at the BTS7960 Module, nice part and not expensive,

if i use this image for my h bridge motor, and connect it into arduino nano, will it work?

It will work with the right control code.

With the wrong code it will be a firework.

I had assumed the code would be correct but I do not know about the hardware as it has not been defined. Do you like my cars old color?

Hi, @salmanaf

What is the application?
What are the motor specs, can you please post a link tp specs/data?

How are you going to power the system?
Do you want to control speed and/or direction?

Thanks.. Tom.. :smiley: :+1: :coffee: :australia:

Based on the datasheets for IRF4905 and IRLZ44N, yes, it should but it depends on the current through the load.
Watch figure 1 and 2 on each datasheet to anticipate the power dissipation in each transistor.
10A will dissipate about 2.5W @ 25°C and 5W @ 175°C in the IRLZ44N (Vgs=4V)
and about 0.8W @ 25°C and 3W @ 175°C in the IRF4905 (Vgs=-10V). Cool them accordingly.

The cooling metal plate on each transistor is connected to the drain (package outline, page 8). It is not insulated from the circuit. Don't connect them together with your cooling device, it would fry something! => use separate cooling devices or TO220 Thermal Insulator Kits.

And of course, make sure P1 and N1 are never EVER conductive simultaneously. Same for P2 - N2. => dead-band delay to prevent shoot-through current.
