2.79V threshold — why it matters for 3.3V rail monitoring
The 2.79V threshold is set for 3.3V systems: it trips before the rail falls below the minimum operating voltage of typical 3.3V logic, giving the downstream MCU or FPGA a clean reset before brownout corruption.

The open-drain output allows wired-OR connection with other reset sources, and the reset timeout is adjustable via an external capacitor — no fixed timer to work around.
