General Description

The MAX6351–MAX6360 microprocessor (µP) supervisors with multiple reset voltages significantly improve system reliability and accuracy compared to separate ICs or discrete components. If any input supply voltage drops below its associated preset threshold, all reset outputs are asserted. In addition, the output(s) is valid as long as either input supply voltage remains greater than +1.0V.
