MAX6381–MAX6390
SC70/μDFN, Single/Dual Low-Voltage,
Low-Power μP Reset Circuits
General Description
The MAX6381–MAX6390 microprocessor (μP) supervi-
sory 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 output. The MAX6382/MAX6385/MAX6388 have
a push-pull active-high reset output, and the MAX6383/
MAX6386/MAX6389/MAX6390 have an open-drain active-
low reset output. The MAX6384/MAX6385/MAX6386 also
feature a debounced manual reset input (with internal
pullup resistor). The MAX6387/MAX6388/MAX6389 have
an auxiliary input for monitoring a second voltage. The
MAX6390 offers a manual reset input with a longer VCC
reset timeout period (1120ms or 1200ms) and a shorter
manual reset timeout (140ms or 150ms).
The MAX6381/MAX6382/MAX6383 are available in 3-pin
SC70 and 6-pin μDFN packages and the MAX6384–
MAX6390 are available in 4-pin SC70 and 6-pin μDFN
packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
