#130001 - that is plain crazy Responding to: ???'s previous message |
find some opamp or comparator on table and build
voltage supervisor. How do you know that the comparator will reach its minimum Vcc (typically they are rated a 5V) BEFORE the uC does something? I have seen all kinds of Mickey Mouse 'supervisors' and all I have seen I have been able to prove faulty. Erik |
