We need to replace the schottky diode that is used in the analog watchdog. It has a turn on voltage that is below what was calculated due to the low bias current. The circuit was designed so that the turn on voltage was about 450mV and it is actually closer to 100mV. Because of this, the watchdog activates the FET when only one flag is raised. The recommendation is to swap out this diode for a regular p/n diode which will have a turn on voltage closer to 0.7V.
