However, if the fault lasts for more than 118 ms, then the
driver turns off and the device enters the V
CC
double hiccup
mode described earlier.

The NCP1219 also has an internal temperature shutdown
circuit. If the junction temperature of the controller reaches
155°C (typical), the driver turns off and the controller
enters double hiccup mode.
Latched and AutoRetry Options
The NCP1219A offers a latched fault circuitry. An
overload fault condition detected by the controller results
in a latchoff shutdown, requiring the controller to be reset
by cycling V
CC
(removing the ac line input). NCP1219B
provides an autoretry circuit. All fault conditions except
the external latch fault result in the controller entering
double hiccup mode, attempting to restart the controller
every other V
CC
cycle, as mentioned earlier.
