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,

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.
