Product Number: ADM1266
I'm using an ADM1266ACPZ device to control the power sequencing for my product. Part of the sequence is to monitor the voltage of the power rails (on VP inputs) and trigger a fault condition when detecting an under-voltage condition. On one particular power rail, during a specific test of the hardware, it's detecting an under-voltage condition. However, when I measure the voltage on the pin during the event it never goes below the limit. I've tried increasing the glitch filter but that doesn't stop the fault condition. Disabling the fault condition makes it go away so it's clearly detecting something and triggering. I have a 100R series resistor with a 100nF cap to ground to reduce the noise. Any thoughts or suggestions welcome.
