Disadvantages

• Limited to voltage monitoring functionality, may not suit all applications requiring more complex supervision features.

Working Principles

The MAX6409BS35+T operates by comparing the supply voltage with the threshold voltage set by the TH pin. When the supply voltage drops below the threshold voltage, the reset output is activated, indicating a low-voltage condition. The device continuously monitors the voltage level and generates the reset signal until the voltage rises above the threshold again.
