What is Tildens H-bridge circuit (i am assuming it is not a traditional H-bridge)?
Not only is his H-bridge a little out of the ordinary (depending as it does on the complementary outputs of a couple of Nv neurons) but he apparently has come up with a newer one that is even more energy-efficient. This circuit depicts Tilden’s H-bridge, no fancy protection though, since an input of 0,0 = Smoke. This H-bridge sketch is accurate but it leaves out a few things, namely the 74C139 which is used as a dual-decoder to avoid the double-trigger = smoke option, and to serve as a dynamic break controller. Note: Inputs to the trigger transistors should have at least 50k Ohm resistors on them. Excerpted from Principa Robotica by Mark Tilden is a section on Biomech Motor Bridges.
