Let's say I have a small h-bridge driver like a TC4427 or a Tilden bridge built up from small transistors and I need to drive a larger motor than the bridge can handle current-wise. Could I not just run the outputs of the bridge through a couple of non-inverting amplifiers or even let them invert, but let the software take care of direction control?
What would the circuit look like or would I have been better off building a beefier h-bridge in the first place? I'm looking to add a power transistor to each output to sink the current of the motor. I'm thinking that this would also add another layer of protection to the MCU.
What do you think?
