Detail
Logic level H (within
40ms) : AC IN is less
than 75Vac typ.
Logic level H (within
40ms) : DC IN is less
than 18Vdc typ.
Logic level H: The Fan
motor anomaly.
Logic level H: PSU has low
output voltage under output
anomaly such as
overvoltage, overcurrent or
inner temperature
anomaly.
It is enabled while
N_MTR_ON is L. If it is H,
N_PWRGD is forced to be
L except under inner
temperature anomaly.
