SC70, Single/Dual Low-
Voltage, Low-Power µP Reset Circuits
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.
The MAX6381/MAX6384/MAX6387 have a push-pull active-low reset out...
