Currently evaluating the LED Driver control signal (white LED) for DMD headlights.
The "LS_SENSE(N/P)" signal is included in "Figure 8-1. Headlight System Block Diagram" of the TPS99001-Q1 spec.
But the HL_Driver of the DLP5531Q1 EVM is not used. What is the purpose and function of the "LS_SENSE(N/P)" signal in the headlight application? Is it a necessary signal?
In addition, the three groups of LED Drivers in the HL_Driver circuit diagram use the same components, but why is the maximum output voltage of LED_Driver_0 (12V) different from the other groups (4V)?
