shutdown and automatic restart, protect the
device against overload. In overload condition,
the channel turns OFF, then back ON
automatically so as to maintain 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
will restart only when the case temperature has
decreased down to T_CR (see Figures 6-7).
Channels that are not overloaded continue to
operate normally.
The device automatically turns OFF when the
Ground pin is disconnected. This device is
especially suitable for industrial applications
which conform to IEC 61131 (Programmable
Controllers International Standard)S
