Figure 4. MAX6763/MAX6764 Functional Diagram
The MAX6754–MAX6764 are low-power window volt-
age detectors capable of monitoring undervoltage and
overvoltage conditions on system power supplies.
Whenever a monitored voltage falls below its undervolt-
age threshold or exceeds its overvoltage threshold,
these devices assert their outputs to notify the system
(see the Functional Diagrams).
The MAX6754/MAX6755/MAX6756 are single-voltage
window detectors with internally fixed nominal voltage,
externally adjustable set window, single reset
under/overvoltage output, and a manual reset input.
The MAX6757/MAX6758/MAX6759 are single-voltage
window detectors with internally set nominal voltage,
externally adjustable set window, separate under/over-
voltage outputs, and manual reset input.
The MAX6760/MAX6761/MAX6762 are dual-voltage
window detectors with internally/externally set nominal
voltages, externally adjustable set window, separate
under/overvoltage outputs, manual reset input, and
overvoltage latch functions.
The MAX6763/MAX6764 are single adjustable window
detectors with separate under/overvoltage outputs.

The MAX6754–MAX6762 offer factory-fixed voltage
thresholds for monitoring system voltages from 0.9V to
5V. The MAX6754–MAX6762 include a SET function to
select the window voltage to ±5%, ±10%, or ±15%. The
MAX6763/MAX6764 allow for externally adjustable
upper and lower voltage thresholds to be set externally
(down to 0.5V). The MAX6754–MAX6762 are available
with two timing options (20µs propagation delay or
100ms minimum reset timeout).
