Low-Power, Single/Dual-Voltage Window
Detectors
General Description
Features
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.
♦ Single- or Dual-Supply Voltage Monitors
♦ Factory-Trimmed Window Threshold Options for
5V, 3.3V, 3V, 2.5V, 1.8V, 1.5V, 1.2V, and 0.9V
Supplies
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.
♦ Externally Adjustable Window Monitoring Options
for Supplies Down to 0.5V
♦ Selectable Window Threshold Options ( 5ꢀ,
10ꢀ, 15ꢀꢁ
♦ Single (Combined UV/OVꢁ or Dual (Separate UV
and OVꢁ Outputs
♦ 20µs (typꢁ or 100ms (minꢁ Timeout Period Options
The MAX6754–MAX6762 offer factory-fixed voltage
thresholds for monitoring system voltages from 0.9V to
5V with a selectable 5ꢀ% 10ꢀ% or 15ꢀ 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.
