Article Why is MAX6389LT28D2+ bench measured reset timeout inconsistent with specification?

Microprocessor supervisory products provide a guaranteed minimum reset pulse because that is important to reliably issue a reset to the microcontroller. 

20ms is the guaranteed minimum reset timeout delay for MAX6389LT28D2+.

The measured result in reality can be ranging from 20ms to 40ms.

Trp definition can be found in EC table on page2 of MAX6389 datasheet.
