The MAX6759 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 MAX6759 monitor a single voltage. The MAX6759 provide independent undervoltage and overvoltage outputs. The outputs are available in push-pull or open-drain configurations.

The MAX6759 offer factory-fixed voltage thresholds for monitoring system voltages from 0.9V to 5V with a selectable ±5%, ±10%, or ±15% window voltage. The MAX6759 are available in two delay timing options (20µs, typ or 100ms, min). The MAX6759 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.
