7.2.6 Analog Output Diagnostic Mode
Due to the low pin count in the application, a wrong operation must be indicated by the output pin OUT. This could be realized using the failure
bands. The failure band is defined with a fixed level. The failure band low is specified from 0% to 4% of the supply range. The failure band high
is defined from 100% to 96%. Several failures can happen during operation. The output signal remains in these bands over the specified
operating and load conditions. All the different failures can be grouped into the internal alarms (failures) and the application related failures.

Table 8. Different Failure Cases of AS5163
For efficient use of diagnostics, it is recommended to program to clamping levels CLL and CLH.
7.2.7 Analog Output Driver Parameters
The output stage is configured in a push-pull output. Therefore it is possible to sink and source currents.
