Gate circuit drawn and described like that make sense.
Funny but I would not of thought of including it, would have done it all with the micro. It occurs to me that you have added another level of security as this will work even with a hung processor. Very nice.
Hmm, just had another thought, the over current protection will be a bit instant. Maybe a good thing, can't think of any real downside. Is it self resetting...no. Is there a circumstance where a short time over-current condition is acceptable ... I guess not better to be safe than sorry. All good.
