Bias and modulation outputs are disabled and SV_CC is opened.
No modulation current.
Pre-bias current is turned off. Does not affect LED power.
Modulation current may increase depending on operating
temperature and TC_SLOPE setting.
Modulation current may decrease depending on operating
temperature and TC_START setting.
The LED is turned off if connected to the LED cathode.
LED modulation is prevented and a fault state occurs. ⁽²⁾

Does not affect LED operation.
The LED is turned off and a fault state occurs. ⁽²⁾
NOTES:
1. In this case a fault state will assert the FAIL output, but it is not latched. While the fault condition remains, the bias and modulation outputs are
disabled and the switch at SV_CC is open. No fault occurs if in Safety Circuit Bypass (SCB).
2. In this case a fault state will assert and latch the FAIL output, disable bias and modulation outputs and open the switch at SV_CC. No fault occurs
if in Safety Circuit Bypass (SCB).
