Diagnostic enable
An unintended LED open or SLS fault can be detected on OUTn in low supply condition on VS or VLED depending on
the Diagnostic group configuration.
The device provides one diagnostic enable threshold related to VS and one diagnostic enable threshold related to
VLED according to following table:

Both diagnostic enable thresholds are stored in the OTP.
Load diagnostic is only available for active-ON channel (duty cycle DC>0ꢀ). Set DC=0ꢀ on unused output will prevent
from receiving spurious warnings. Exception is OUT_SHORT_WRN which is also available with DC=0ꢀ, but it can be
disabled via OTP.
If the device is in ACTIVE, FAIL-SAFE or OTP modes and VS or VLED are below their respective VDEN_THRESHOLD, the
device reports an VLED_VS_UV in the output status byte.
