Hi,

Could you tell me about open load detection threshold current?



Customer want to increase this threshold.
Is there a way to increase the threshold current value?
Or do you have a product with a high threshold?

    Hello,
    What is the current threshold customer is looking for? what is the load current? Does the application need continuous current monitering?

    Mahmoud-san,

    Thank you for your response.

    What is the current threshold customer is looking for?
    →I have not received that information.

    What is the load current?
    →Target current limit value is not fixed.

    Does the application need continuous current monitering?
    →I have not received that request.

    Do you know the recommended product or how to do it?

    Best Regards,

    Yusuke-san,
    The open load detection in on state has wide limit and accuracy is not great. For that reason I suggest using the TPS1H100B-Q1. The current sense accuracy, at 25mA, is 10%. The judgment for open load detection is user's decision. It can be measured at CS pin and define the Vsc voltage level to be considered as open load. I hope this helps and let me know for further support.

    Regards
