Overview

19-2656; Rev 1; 1/03 µP Reset Circuits with Long Manual Reset Setup Period General Description The MAX6443–MAX6452 low-current microprocessor reset circuits feature single or dual manual reset inputs with an extended 6.
72s setup period.
Because of the extended setup period, short switch closures (nuisance resets) are ignored.
On all devices, the reset output asserts when any of the monitored supply voltages drops below its specified threshold.
The reset output remains asserted for the reset timeout period (210ms typ) after all monitored supplies exceed their reset thresholds.
The reset output is one-shot pulse asserted for the reset timeout period (140ms min) when selected manual reset inpu...
