Assuming that you are already familiar with the concept of H-Bridge, this page is just to show you an example of single chip solution that provide 2 H-bridge in it. You may find a good example showing how the H bridge is really implemented at the level of commerical product. You can get the detailed datasheet from Reference [1]. I will mark the trace to show the H-Bridge operation, so that you can easily correlate the internal chipset circuit and H-Bridge operation.

 

 

 

You can easily find a module (DC Motor Driver Module) that is using L298 as shown below. I used one of these for my Arduino and it was really handy and worked well.
