MAX6390 Datasheet (Maxim Integrated Products)

MAX6390, Low-Power uP Reset Circuits

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 tim
