Hi,
there are two issues when we use the UCD90160A. could you please help to fix it?
1. The monitored voltage is correct, and GPIs was ignored. but the PMBALERT is still low when our board works.
2. If a warning occurs, for example, the power input shuts down, can i turn off some of the power rails immidiately and do not turn off the others? and how to configure it? I can not find the items on Fusion Digital Power designer.
Thanks a lot!

Hello
Please see my comments below.
1. PMBALERT is a latch status indicator and once a exception is detected, it does not self-clear even the exception is gone. You can view the status of the device from Fusion GUI to see what had happened. Follow below training video.
#2.yes, UCD90160A provides very flexible ways to configure the fault response. please refer the quick guide attached(refer fault response section)
