Working Principles

The MAX810LTRG operates by comparing the supply voltage with a preset threshold. When the voltage falls below the threshold, the internal circuitry generates a reset signal, which remains active until the voltage rises above the threshold or a timeout period elapses. The manual reset input allows for immediate system reset when required.
