AEC-Q100 grade-1 reset for underhood rails
It monitors a single voltage rail and asserts an active-low, open-drain reset when the supply drops below the 1.2 V threshold.
1.2 V threshold and open-drain output
The 1.2 V threshold targets low-voltage core rails in automotive ECUs — any drift below this window triggers a system reset, protecting the microcontroller from brownout. The open-drain output allows wired-OR connection with other reset ICs or pull-up to a different voltage rail, common in multi-voltage systems where one supervisor monitors the 1.2 V core while another watches the 3.3 V I/O rail.
