H-Bridge
June 28, 2023
Some important features for a motor-driver are:
- stackable
- cheap
- easy to drive
- low standby current
- able to mount heat sinks
The idea behind an H-Bridge
History
From left to right: Version 1.0, Version 3.0, Version 5.0
All H-Bridges are going to have secured heat sinks because of the moving robots
Newest version:
This is the circuit for the H-Bridge 6.0
This is the board for the H-Bridge 6.0
Mass production of these boards
Switching speed test
The rise time is very good but the fall time could be improved. But it works fine with such a low PWM signal.
Update from July 19, 2023
I added a shoot through protection for extra safety.
Update from September 02, 2023
This is the version 8 of my H-Bridge. Its control circuit is done with nMosfets [IRLML6246TRPBF] to reduce the needed current from the uC.
It has the security ciruit already built in.
And on September 04, 2023 there is already a newer version :D The 8.1
It eliminates some issues with the heat sinks and the LED cover up by the same.
Update from September 21, 2023
All 9 H-Bridge modules are finished and ready to be used to control some heavy motors.

I decided to make four more and this time they are a Meme version of the 8.1:

This time the design is the "Doge" which i really like:
