4.2
The device provides embedded protective functions. Integrated protection functions are designed
to prevent IC destruction under fault conditions described in the target data sheet. Fault conditions
are considered as “outside” normal operating range. Protection functions are neither designed for
continuous nor repetitive operation.
4.2.1
The load current
There are two steps of current limitation. They can be selected by the CLA pin, but are
additionally selected automatically depending on the voltage
Please note that the voltage at the OUT pin is
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
Figure 11
The CLA pin circuit is designed equal to the input pin. Please refer to
note that the thresholds for high and low state differ between IN and CLA.
