MAX6754 Datasheet, PDF (1/22 Pages) Maxim Integrated Products – Low-Power, Single/Dual-Voltage Window Detectors

19-3075; Rev 1; 12/03
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.

*Note: 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.
