The MXD1818UR29+T: The 2.88V threshold is set for monitoring a nominal 3.0V or 3.3V supply rail. When the rail dips below 2.88V, the reset output pulls low and holds for at least 100ms after the rail recovers above the threshold. This timeout gives the system clock and core logic time to stabilize before the processor starts executing code.
