4.2
The device is fully protected by embedded protection 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.

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
