The outputs are provided with a current limitation that
enters a repetitive switched mode after an initial peak
current has been exceeded. The initial peak short
circuit current limit is set to I
the repetitive mode short circuit current limit is set to

condition, a second protection level (T
change the output into a low duty cycle PWM (selective
thermal shutdown with restart) to prevent critical chip
temperatures.

The following figures show the timing for a turn on into
short circuit and a short circuit in on-state. Heating up
of the chip may require several milliseconds,
depending on external conditions.

The overtemperature detection information are OR-
wired in the common diagnostic output block. The
information is send via the integrated coreless
transformer to the input interface. The output stage at
pin DIAG has an open drain functionality combined with
a current source.
