I don’t think it is an Eagle thing necessarily, just the source of where the footprint came from. You just must of had a good footprint to start with.

diptrace sounds pretty cool though!

edit: the issue with the silks probably is Eagle, if that’s what you were referring to

Very possible, I just picked a random component with the footprint, guess I got lucky.

Really nice work TA. Love the organic layout. I haven’t been keeping up on driver ciruits. So I may have missed recent developments. I’m curious about the voltage divider being fed by R5. Doesn’t that make the cumulative resistance of 9.4 26.7 ohms after passing R2 R1?

Power to the MCU also goes through R5 (and then the polarity protection diode). What is the purpose for R5? I’m certain you have it there for good reason. I’m probably not aware of issues that it must remedy.

EDIT: Fixed error.

Thanks, it was a learning experience but a fun one that I think turned out pretty good.

Far as the questions about the circut, like I said in the OP, it is not mine, it is blatantly stolen from DEL and all the people before him. He would be the one to ask about all of that.

You can see the discussion on it in this thread: Attiny25/45/85 FW Development Thread

Basically these changes came about when DEL was scoping out the new Q8 driver, he determined that these changed provided a much more stable and reliable driver overall as it was getting some nasty voltage spikes with the classic circuit.
