MAXIM MAX16055AAUB+

The MAX16055 hex voltage μP supervisory circuit maintains system integrity in multisupply systems. The MAX16055 offers accurate, factory-fixed undervoltage threshold options for monitoring very low voltages. The MAX16055 also offers one to five adjustable thresholds for monitoring voltages down to 0.5V. The MAX16055 includes an accurate voltage reference, precision comparators, and a series of accurate internal resistor-divider networks to set the factory-fixed reset threshold options for monitoring 3.3V, 3.0V, 2.5V, 1.8V, 1.5V, 1.2V, 1.1V, 1.0V, or 0.9V supplies. The resistor networks scale the specified N- threshold voltages to match the internal reference voltage. Adjustable threshold options allow the monitored voltage to be connected to the input of the internal comparator. Use an external voltage-divider to set the threshold voltage.
