Other Parts Discussed in Thread: LM25066,
I am not able to understand intended meaning of statement "The LM25066 will pull the SMBA pin low after the input voltage has exceeded its POR threshold to indicate that the volatile memory and device settings are in their default state." on page 18 of LM25066A datasheet. Is not it supposed to be a desirable condition and should not be a fault ? Or it is related to Fault Timer. Could not simulate and check as do not have Spice model of LM25066A.
