TPS2595: Current limit response time

BJ Han
Expert 2035 points
Part Number: TPS2595

Dear TI,

I have additional questions.
-. Over Current threshold : 250us
=> What is the scope of OCP awareness?
=> It has been confirmed that the above value changes according to the output current.
ex) Ouput current : 4.2A / 250us and 6A / 120us
This is the part that is needed to get the reference point in the MCU.

The current limit response time is getting shorter as the current increases.

Please check the reference point.

    Hi Han,

    The current limit response time was measured under the test condition "IOUT > ILIMIT + 20% to IOUT ≤ ILIMIT". The typical value is 250us. We can expect faster response with higher overload step.
    Can you help me understand the importance of this parameter in your system, what are the system specifications and what information is fed to MCU?

    Best Regards,
    Rakesh
