Low-Power, Single/Dual-Voltage Window
Detectors
General Description
The MAX6754–MAX6764 low-power window detectors
monitor undervoltage/overvoltage conditions on system
power supplies. These devices assert when the moni-
tored voltage is under the undervoltage and/or over the
overvoltage thresholds.
The MAX6754–MAX6759/MAX6763/MAX6764 monitor a
single voltage. The MAX6760/MAX6761/MAX6762
monitor dual-voltage systems. The MAX6754/MAX6755/
MAX6756 provide a single undervoltage/overvoltage
output and the MAX6757–MAX6764 provide indepen-
dent undervoltage and overvoltage outputs. The out-
puts are available in push-pull or open-drain
configurations.
The MAX6754–MAX6762 offer factory-fixed voltage
thresholds for monitoring system voltages from 0.9V to
5V with a selectable ±5%, ±10%, or ±15% window volt-
age. The MAX6763/MAX6764 allow for externally
adjustable thresholds. The MAX6754–MAX6762 are
available in two delay timing options (20µs, typ or
100ms, min). The MAX6760/MAX6761/MAX6762 also
include a latched overvoltage output function and the
MAX6754–MAX6762 include a manual reset input.
The family of products is available in small SOT23 and
TDFN packages and is specified over the extended
temperature range of -40°C to +125°C.

*Insert
the threshold level suffixes for V
CC
and V
CC2
(Tables 1
and 2) after UK, UT, or TA. For the MAX6754–MAX6759, insert
only the V
CC
threshold suffix after the UK or UT. Insert the reset
timeout delay (Table 3) after D to complete the part number. For
example, the MAX6760TALTD3-T provides a V
CC
threshold of
5V, a V
CC2
threshold of 3.3V, and a 100ms minimum reset time-
out period. Sample stock is generally held on standard versions
only (see the Standard Versions table). Standard versions have
an order increment requirement of 2500 pieces. Nonstandard
versions have an order increment requirement of 10,000 pieces.
Contact factory for availability.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.

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.
