Thanks Harry, Uwe, & Bertram for the replies. The full circuit (A strange display device) contains the capacitor block, and each of the common legs has an intregal diode in series, and everything is resistive, particularly the tracks out to my drivers. The diodes are also hugely capacitative; think of them as a diode with a large capacitor in series.
What's puzzling is that switching is faster than the time constant of these things is faster than the resistance and capacitance would calculate out. I had a phenomenon before of cells which weren't being driven actually receiving charge. This occurred on one prototype. I want to try and understand the electronic theory of it - I need to for the next stage. I'll draw something out in detail and then return with it. -- Regards, Declan Moriarty. -- Author: Declan Moriarty INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB CHIPDIR-L (or the name of mailing list you want to be removed from).
