Working Principles

The MAX6729KAYDD3+ operates by comparing the monitored voltage with a user-defined threshold voltage. When the monitored voltage falls below the threshold, the active-low reset output is asserted, indicating an undervoltage condition. Conversely, when the monitored voltage exceeds the threshold, the reset output is deasserted. The trigger input allows for manual reset of the IC.
