SC70/µDFN, 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 V
CC
falls below the factory-set reset
thresholds, the reset output asserts and remains assert-
ed for a minimum reset timeout period after V
CC
rises
above the reset threshold. Reset thresholds are available
from +1.58V to +4.63V, in approximately 100mV incre-
ments. 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 V
CC
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.

RESET
Active-High Push-Pull Reset Output.
RESET changes from low to high when
any monitored voltage (V
CC
or
V
RESETIN
) drops below the reset
threshold or
MR
is pulled low. RESET
remains high for the reset timeout
period after monitored voltages exceed
the reset thresholds or
MR
is released.
Active-Low Open-Drain/Push-Pull Reset
Output.
RESET
changes from high to low
when any monitored voltage (V
CC
or
V
RESETIN
) drops below the reset threshold
or
MR
is pulled low.
RESET
remains low for
the reset timeout period after the monitored
voltages exceed the reset thresholds or
MR
is released. Open-drain requires an
external pullup resistor.

MR
Active-Low Manual Reset Input. Drive
low to force a reset. Reset remains
active as long as
MR

MR
has an
internal 63kΩ (1.56kΩ for MAX6390)
pullup resistor to V

.
Auxiliary Reset Input. High-impedance
input to the auxiliary reset comparator.
Connect RESET IN to the center point of
an external resistor voltage-divider
network to set the reset threshold voltage.
Reset asserts when either V
