Different error cases can be detected by the OBD (On-Board-Diagnostics) and reported
to the µController. The OBD is only useful when the clamping function is enabled.
It is important to set the clamping threshold values inside the error voltage values shown
in
So it is possible to distinguish between correct output voltages and error signals.
7.1
The output signals error conditions, if
• inside the ratings specified in
• outside the range specified in
