#127705 - if overvoltage crowbars Responding to: ???'s previous message |
instead of blowing fuse ,which needs replacements
It should blow a fuse, because you need to know if overvoltage happens you have these possibilities 1) your design is wrong 2) something else is wrong 3) a component failed should there not be 'attention' in either case. Making the overvoltage crowbar a design feature rather than "protection against ripple effects of a failure" is one of the most obnoxious applications of electronics I can imagine. Erik |
