Working Principles

The MAX6837FXSD3+T is a voltage supervisor IC that continuously monitors the supply voltage. It compares the voltage level with the selected threshold voltage and generates a reset signal when the voltage falls below the threshold. The reset signal remains active until the voltage rises above the threshold or a timeout period elapses. The manual reset input allows external control over the reset signal. The IC operates with low power consumption, making it suitable for battery-powered applications.
