Data Sheet
Timing diagrams
Timing diagrams are shown for chip 1 (channel 1/2). For chip 2 (channel 3/4) the diagrams
are valid too. The channels 1 and 2, respectively 3 and 4, are symmetric and consequently
the diagrams are valid for each channel as well as for permuted channels

Heating up of the chip may require several milliseconds, depending
on external conditions (t off(SC) vs. T j,start see page 12)
