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.
Yes. The 2.79V threshold is specifically chosen for 3.3V rails — it triggers before the rail falls below the minimum operating voltage of 3.3V logic, ensuring a clean reset.
