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.

threshold suffix after

the UK or UT. Insert the reset timeout delay (

Table

complete the part number. For example, the MAX6760TALTD3-T
provides a V

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.
