Using the LT4356-3 device we find an its anomalous behavior: on an overvoltage event on the Vcc we obtain a final state of the device out of specification with a FLT signal low, but the OUT pin active (high).
What could determine such an anomalous behavior? Can the absence of a capacitor placed on the OUT pin (as indicated in some, but not alla diagrams of your application note) determine this behavior?
Thank you,
Nicola
