MOSFET H-Bridge With Current Limiting Control

A simple MOSFET H-Brighe circuit with a current source to control the current that can flow through the coil. Current limiting is necessary for example stepper motors so can drive them in the optimal current range.
Hfe = 90 (current limiter transistor)
Uses logic level MOSFETs
And if needed, add some flyback diodes for protection.

Hi, Nice Video. Keep them!. What is this software name?

[@PeetHobby]

Thx, name is circuitjs

Project link?

[@phelelanizwane8870]

hello which components did you use for high and low

[@PeetHobby]

Those can be signals for MCU, or switch or anything that with the logic level of those inputs. Or did you mean the MOSFETs?

Thank U.

I use Circuitjs

Usually i use everycircuit, but still have bug

[@PeetHobby]

@@oprekngawur2601 Circuitjs has also a lot of bugs, and (almost ) all the componts are ideal components. So don't use it for real circuit simulations, use LTspice or other sim with database of real wold components, those will give you much better results.

@@oprekngawur2601 I'm not familiar with proteus. They offer only a paid version I think?

Where is the power source for motor? My biggest confusion is how does the current flow with 2 power sources? 5v being the internal logic and other power source for motors.

[@PeetHobby]

There is only one power supply. If you see multiple positive traces in the schematic with the same name, such as +5V, it means they are all connected to the same +5V trace. Therefore, all the +5V connections in this motor example are linked to the same power supply.
