MP6400 - MPS

MP6400 Low Quiescent Current Programmable-Delay Supervisory Circuit

The MP6400 family is the microprocessor (µP) supervisory circuit which can monitor and provide reset function for system voltages from 0.4V. When either the SENSE voltage falls below its threshold (VIT) or the voltage of manual reset (MR ) is pulled to a logic low, the RE SE T signal will be asserted. The reset voltage can be factory-set for standard voltage.
