Diagnostic on Outputs 1 and 2 controlled via NON1/NON2
Fault condition (1) "output shorted to Vbat"
The output has been previously switched-on and its voltage exceeds the diagnostics
threshold. It operates in current regulation mode or it is switched-off if thermal shutdown
threshold (T
Fault condition (2) "open load" or "output shorted to GND"
The output is switched-off and its voltage drops below the diagnostics threshold because
the load current is lower than the output diagnostic current source. The diagnostic bit is low.
Table 8.
Diagnostic on Outputs 1 to 8 controlled via SPI
Fault condition (1) "output shorted to Vbat"
The output was previously switched-on, its voltage exceeds the diagnostic threshold and the
result is that the output is switched-off. The diagnostic bit is high.
Fault condition (2) "open load" or "output shorted to GND"
It is the same behavior explained for the outputs 1 and 2 (see paragraph 5.3.1), at NCS
falling edge the output status data are transferred to the shift register.
Table 9.
Load diagnostic: when the output is in OFF condition a typical diagnostic current of 60 µA is
sinked.
