Original question:

TPS25982: Current limit RILIM setting lower than 82ohm which is the min value in datasheet

TPS25982: Circuit breaker ICB min value

Part Number: TPS25982
Other Parts Discussed in Thread: LM25066, TPS24720

Hi Team,

Also, the customer are using “TPS259827O” which is a circuit breaker type.
Please help to check if they can use Rilim to GND (0ohm) get about 20A circuit break point (This meet spec also 20A is close to our test result of now).

If this is workable, please kindly share what is min of ICB.

Also, it seems that the RILIM minimum value of TPS259827O is not limited by the DS recommend Operating Conditions

Can the customer use RILIM as 64.9 ohm in their design? Thank you.

Best regards,

Mike

    Hi Mike,

    Thanks for reaching out!

    As mentioned in the other E2E thread, the part is not recommended to use for continuous current > 15A. So please do not use a Rilm resistor < 100 ohms. 

    For high current needs, use TPS24720 or LM25066

    Best Regards, Rakesh
