Fit and timing for the BOM line
The MAX6381XR25D2: The 2.5V threshold is the critical selection parameter — it matches a 2.5V core or I/O rail where the supervisor must trip before the downstream logic enters an undefined state. The 20ms minimum reset timeout holds the processor in reset long enough for the rail to stabilise after a brown-out or power-up, covering the typical power-good window for 2.5V LDOs and switching regulators. The SC-70-3 (SOT-323) package footprint is common and easy to hand-assemble or rework — the 0.65mm lead pitch is visible under a standard inspection microscope.
