Working Principles

The MAX809SN293D3T1G is designed to monitor the supply voltage of a system. It compares the input voltage with a fixed threshold voltage and asserts the reset output when the supply voltage falls below this threshold. The reset output remains active-low until the supply voltage rises above the threshold and the reset timeout period elapses.
