Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe MAX6754MAX6764 low-power window detectors monitor undervoltage/overvoltage conditions on system power supplies. These devices assert when the monitored voltage is under the undervoltage and/or over the overvoltage thresholds.
The MAX6754MAX6759/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 MAX6757MAX6764 provide independent undervoltage and overvoltage outputs. The outputs are available in push-pull or open-drain configurations.
The MAX6754MAX6762 offer factory-fixed voltage thresholds for monitoring system voltages from 0.9V to 5V with a selectable ±5%, ±10%, or ±15% window voltage.
The MAX6763/MAX6764 allow for externally adjustable thresholds. The MAX6754MAX6762 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 MAX6754MAX6762 include a manual reset input.
The MAX6754 is available in small SOT23 and TDFN packages and is specified over the extended temperature range of -40°C to +125°C.
