I mentioned in the wiki that it may be appropriate to use the charge pump detector as _part_ of an e-stop system. E-stop is a bigger subject than charge pump. This may or may not be something I'll have time to get to. Oops, I now realize you're saying that e_stop_latch has a charge pump like feature? I'll look into it, thanks. > And just comment for 567 circuit. The 5V peak > to peak is little high for them. Just use voltage divider (1/10 ratio) > on input and should work. Yes, I noticed the .2V RMS recommended maximum mentioned in the app. note. I used a 5k potentiometer as a voltage divider and found that the output changed fairly randomly at different settings for the same frequency. Varying the frequency also had peaks and valleys, which was fairly discouraging. Pulse behavior, as opposed to 50% duty, wasn't very good. I need to get the scope out to see whats going on, but the cap/diode and AVR circuits already work well, so I'm beginning to loose interest in this one. If anyone has a working, or near working, circuit (with square wave or pulse input), I can post it, but I'm not certain I'll do much more with the 567. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Gaining the trust of online customers is vital for the success of any company that requires sensitive data to be transmitted over the Web.
