#92679 - what's exactly the problem? Responding to: ???'s previous message |
What is your problem exactly?
Do you want to avoid RESET during 230VAC failure? Or do you want determined state of the Powerdown signal. In the latter case, please post the powerdown circuit. Just a hint, a Zener in series of RESET (and maybe POWERDOWN too) might help. Jan Waclawek |
