Timing diagrams
Both channels are symmetric and consequently the diagrams are valid for channel 1 and
channel 2

Figure 2b: Switching a lamp:
Figure 3a: Turn on into short circuit:
shut down by overtemperature, restart by cooling
Heating up of the chip may require several milliseconds, depending
on external conditions (t off(SC) vs. T j,start see page 10)
The initial peak current should be limited by the lamp and not by
the initial short circuit current I
