MPQ6400 Overview
The MPQ6400 is a microprocessor (µP) supervisory circuit which can monitor and provide a 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 RESET signal will be asserted. Fixed voltage threshold options set by the factory are available for standard voltage rails between 0.9V and 5V, while the...
