MAX6754–MAX6764
Low-Power, Single/Dual-Voltage Window
Detectors
Benefits and Features
General Description
The MAX6754–MAX6764 low-power window detec-
tors monitor undervoltage/overvoltage conditions on
system power supplies. These devices assert when the
monitored 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 independent
undervoltage and overvoltage outputs. The outputs 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 voltage.
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.
This 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 timeout 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.
