Active current limitation combined with thermal
shutdown and automatic restart, protect the
device against overload. In overload condition,
the channel turns OFF and back ON
automatically so as to maintain the junction
temperature between T
TSD
and T
R
. If
this
condition makes the case temperature reach
T
CSD
, the overloaded channel is turned OFF and
restarts only when the case temperature has
decreased to T
CR
(see waveform 3 Figure7 on
page10). Non overloaded channels continue to
operate normally. The device automatically turns
OFF in the case of a ground pin disconnection.
This device is especially suitable for industrial
applications and conforms to IEC 61131.
