Threshold selection and reset timing
The MAX6352MSUK-T: The two monitored thresholds (2.93V and 4.38V) cover common logic rails: the 2.93V threshold suits a 3.3V supply with a typical undervoltage lockout margin, while the 4.38V threshold catches a 5V rail before it drops below the minimum operating voltage of downstream 5V logic. A minimum reset timeout of 100ms holds the reset line low after all monitored rails return above threshold, giving the system power-on reset time to stabilize before the processor starts executing code.
