TPS25947: Clarification on IFLT Current

Part Number: TPS25947

Tool/software:

Hello,

I am working with the TPS259470 and have a question regarding the IFLT current mentioned in the datasheet. Specifically, I would like to know which current path the IFLT parameter refers to.

Electrical Characteristics

I have attached a diagram to illustrate my question. In the diagram, there are two possible current paths marked with a blue arrow and an orange arrow. Could you clarify whether the IFLT corresponds to the current shown by the blue arrow or the orange arrow?

Any clarification or additional details would be greatly appreciated.

Thank you for your support!

Best regards,

    Hi Yuya,

    When the ILIM pin is left open, If the orange arrow current exceeds IFLT value, the device will perform circuit breaker operation. 

    I hope this answers your question.

    Please feel free to reply back with any follow back question.

    Best Regards,
