Functional Description
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.
