My proof is good enough for me, and I read that Jan's proof is good enough for him. If it is not good enough for you, THEN FIND IT YOURSELF!!!!!! Agree! Since we use MAX1232 we never had even the least trouble. So, to say, that the reset chip solves the problem is scientific enough for me. Also, what you Richard propose, namley to clamp Vcc to ground results in new problems, even more harmful problems. You once told us, that you would analyse the rise time issue. Please do so and present your results, but please stop telling us, that the reset chip won't solve anything. That's just not what we all observe every single day. Kai I'm not looking for a proof! (Not to suggest that any proof has been offered. These have, so far, been, at best, guesses! I've been asking all along, "What are the observations that you've made?" Why? Because before I set up multiple circuits in a carefully monitored and voltage/temperature-controlled 1000-hour test, I want to know what observations people have made in order to establish that there IS a verifiable RESET problem. I don't doubt that there is one, but I need to know how it (the reset problem) has manifested itself in terms of rigorously observable, measurable parameters. Up to this point, I've not seen one exercise involving anything other than turning on/off the power. What about the comparison of power-on behavior with behavior in combination with a RESET switch, just as one example. These purely anecdotal "stories" don't mean very much until details are discussed, and, particularly, until the reset problem is defined in terms of RESET alone, and not in combination with changing Vcc. That is part of a later discussion probably involving power-monitor/supervisors. RE |
