Re: LMD18201

The 10k resistors between the micro and the controller is not a problem. The input impedance of the controller is very high, therefore the nominal current through the resistor is negligible, therefore the nominal voltage drop across the resistor is negligible.

Any spikes/transients are essentially isolated by the 10k resistor. The is very much desired in order to protect the micro.

High frequencies and high currents are basically relative matters.

As for the switching waveforms I think (I'll investigate more) that is essentially correct.
