TPS25926: The current limit.

Kengo.Y

Part Number: TPS25926


Hi team,

I'd like to know about the current limit.

When the load current was slowly increased, the current limit was applied above the set value.
Why is this?
We set it at 4.3A(120kΩ), but the current limit was applied at 6A.

Sincerely.
Kengo.

    Hi Kengo,

    What kind of load is being used?  Is the result accurate when current slew rate is fast?

    Can you share any  waveform for efuse input pin voltage, output pin voltage and current through device?

    Regards

    Hi Kunal,

    Thank you for your reply.

    My customer is using an electronic load.
    The output current is increased from 0A to 5.3A over a few seconds to 10 seconds.

    They can't seem to measure it right now, could you give me some advice from this situation?

    Sincerely.
    Kengo.

    Hi Kengo,

    It is not recommended to test efuse device with eload and specially in CC mode. It can give inaccurate results. Please ask them to try preferably with resistive load or they can also try with eload in CR mode.

    Regards
