Buffered H-Bridge from Vishay

si9986sHaving half a mind on the challenge of half-size micromouse, I was looking at some information on the megabitty controller. As supplied, it may well have enough features to make a micromouse controller but that wasn’t what caught my eye. On the board are two full-bridge motor drivers. While looking for data on these, I came across the slightly more flexible Si9986, also by Vishay…
