4.2
The device provides embedded protective functions. Integrated protection functions are
designed to prevent IC destruction under fault conditions described in the data sheet.
Fault conditions are considered as “outside” normal operating range. Protection
functions are neither designed for continuous nor repetitive operation.

The load current
ground. There are three steps of current limitation which are selected automatically
depending on the voltage
the OUT pin is
Figure 10
Current limitation is realized by increasing the resistance of the device which leads to
rapid temperature rise inside. A temperature sensor for each channel causes an
overheated channel to switch off to prevent destruction. After cooling down with thermal
hysteresis, the channel switches on again. Please refer to
Figure 11
In short circuit condition, the load current is initially limited to
