What it is
An H-bridge in 3D with four transistors around a motor. You close the switches and see where the current flows: forward, reverse, brake or coast. If you close two on the same side, you make a short.
- Four switches you can close one by one
- Forward, reverse, brake and coast
- A mode to break it: the same-side short
Use it on the roadmap
- Stage 3. Motors, drivers and sensors
Our lab: what is inside a driver like the TB6612FNG or the L298N.
