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.

steps of current limitation which are selected automatically depending on the voltage V
Please note that the voltage at the OUT pin is V
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
