Part Number:UCD9090A
Hello,
I am using a ucd9090a to monitor and sequence 7 rails.
As a start, I have a master 3.3V that is powered up
1) I monitor the rail. once the rail reaches 3.3V -5% I declare power good
2) I then enable my second rail once this power good logic occurs + 10000ms delay. However I do not see this sequencing occur. I have included my project in this thread. It seems to be fairly straight forward, but I do not see a delay between the two rails.
regards,
