SC70/µDFN, Single/Dual Low-Voltage,
Low-Power µP Reset Circuits
81–MAX6390
General Description
Features
o Factory-Set Reset Threshold Voltages Ranging
from +1.58V to +4.63V in Approximately 100mV
Increments
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
falls below the factory-set reset

ed for a minimum reset timeout period after V 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

resistor). The MAX6387/MAX6388/MAX6389 have an
auxiliary input for monitoring a second voltage. The

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.

Reset asserts when V
is below the reset threshold;
CC
once V
exceeds the reset threshold, an internal timer
CC
keeps the reset output asserted for the reset timeout
period. After this interval, reset output deasserts. Reset
output is guaranteed to be in the correct logic state for
V
≥ 1V.
CC
Manual Reset Input (MAX6384/
MAX6385/MAX6386/MAX6390)
Many µP-based products require manual reset capabil-
ity, allowing the operator, a test technician, or external
logic circuitry to initiate a reset. A logic low on MR
asserts reset. Reset remains asserted while MR is low,
81–MAX6390
and for the reset active timeout period (t ) after MR
RP
returns high. This input has an internal 63kΩ pullup
resistor (1.56kΩ for MAX6390), so it can be left uncon-
nected if it is not used. MR can be driven with TTL or
CMOS logic levels, or with open-drain/collector outputs.
Connect a normally open momentary switch from MR to
GND to create a manual-reset function; external
debounce circuitry is not required. If MR is driven from
long cables or if the device is used in a noisy environ-
ment, connecting a 0.1µF capacitor from MR to GND
provides additional noise immunity.
RESET IN Comparator
(MAX6387/MAX6388/MAX6389)
RESET IN is compared to an internal +1.27V reference.
If the voltage at RESET IN is less than 1.27V, reset
asserts. Use the RESET IN comparator as a user-
adjustable reset detector or as a secondary power-sup-
ply monitor by implementing a resistor-divider at RESET
IN (shown in Figure 1). Reset asserts when either V
CC
or RESET IN falls below its respective threshold volt-
age. Use the following equation to set the threshold:
