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
steps of current limitation. They can be selected by the CLA pin, but are additionally selected automatically
depending on the voltage V
Please refer to following figure for details.
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
picture of the behavior, when
toggling.

The CLA pin circuit is similar to the input pin. Please refer to
for high and low state differ between IN and CLA.
