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.

only the V

timeout delay (Table 3) after D to complete the part number. For

example, the MAX6760TALTD3-T provides a V

5V, a V

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.
