General Description

The MAX6381–MAX6390 microprocessor (μP) supervisory circuits monitor power-supply voltages from +1.8V to +5.0V while consuming only 3μA of supply current at +1.8V. Whenever VCC falls below the factory-set reset thresholds, the reset output asserts and remains asserted for a minimum reset timeout period after VCC rises above the reset threshold. Reset thresholds are available from +1.58V to +4.63V, in approximately 100mV increments. Seven minimum reset timeout delays ranging from 1ms to 1200ms are available.
