We have a design with an UCD9240 and three single-phase power rails using the PTD08A006W. We are having some trouble debugging start-up problems as the system seems to log faults on all the rails during shut-down (it could be start-up, but this seems less likely).
After what seems like a normal shut-down and start-up we see faults logged for all the rail lines. Any idea what condition could be causing this? (total consumption is less than 1/2 of PTD maximums).
