Hi,
I'm designing a pcb which is supposed to generate 24V outputs controlled by a microcontroller. As those outputs go to external devices, I want to protect my circuit against external problems such as short circuits polarity inversion ... My question is about the isolation of the ground because I don't know if I'm suppose to have separated ground between my microcontroller and the power outputs and how to connect it each over with a diode or something else. Something else I think it's strange that there is no input capacitors.
Thanks
