Case 2:
The “Extended blanking time” feature happened first
and it follows with the “Auto-restart enable” feature.
Then the “Auto-restart enable” feature will take the
priority and the “Extended blanking time” feature is
overridden.
Case 3:
The “Extended blanking time” feature happened first
and it follows with the “Brownout” feature. Then the
“Extended blanking time” feature will continue to work
until it ends. After that if the over load fault is removed
the “Brownout” feature takes the action.
Case 4:
The “Brownout” feature happened first and it follows
with the “Auto-restart enable” feature. Then the
“Brownout” feature will continue to work and the “Auto-
restart enable” feature is ignored.
One typical case happened is that the “Extended
blanking time” feature happened first and it follows with
the “Brownout” feature. If, however, the over load fault
is removed before the end of the extended blanking
time, the “Brownout” feature can take action only after
20ms buffer time.
