LP5861T: Short detection

Part Number: LP5861T

Hello team,

I have some question about short detection feature.

  1. After detecting short at one of the CSx channel, will it disable the current sink? OR is it just going to set Global_LSD register = 1 and do nothing?
  2. What is LSD removal function? On the datasheet, it says it will turn off the deghosting function. Will it disable the current sink when LED short is detected?
  3. Is there any way I can disable LED short or open detection?

Best Regards,
Kei Kuwahara

  • Hi Kei,

    Please refer the below comments for your questions:

    1. After detecting short at one of the CSx channel, will it disable the current sink? OR is it just going to set Global_LSD register = 1 and do nothing?

    [Jared]: No it will not disable current sink. As you said, it just sets LSD flag and do nothing.

    2.What is LSD removal function? On the datasheet, it says it will turn off the de-ghosting function. Will it disable the current sink when LED short is detected?

    [Jared]: As the datasheet shown, the LSD removal only turn off the upside de-ghosting function.

    3.Is there any way I can disable LED short or open detection?

    [Jared]: I am sorry it seems that LP5861T can't disable LSD and LOD detection.

    Can you please tell me if there is any conflict with your application?

    BR, Jared
