11. MLX91210 Self Diagnostic

The sensor provides self-diagnostic features to detect internal memory errors and under-voltage. These

features increase the robustness of the IC functionality as they prevent erroneous output signal in case of

internal or external failure modes. This detection is guaranteed provided the measured signal does not

diagnostic as well.
