Hello, I am getting ready to do a pcb layout for the h-bridge configuration below which will serve to drive a brushed dc motor. This circuit is for my senior design and i would like to implement best practices to have a fully working circuit. My plan was to have a 4 layer board with a power plane at the top and a ground plane at the bottom and just connect all my low voltage traces in the 2nd and 3rd layer. I have been thinking about adding a bulk capacitor, but i am not sure if that would be necessary. I would appreciate any input, thanks.
