TPS2113A: current limit accuracy with 2A

Part Number: TPS2113A

Hi,

I am using the current limit function of TPS2113A centered to approximately to 2A (Rlim=253Ω).
I've found on datasheet the current limit accuracy for Rlim to 700Ω and 400Ω, but not an indication about how accuracy change with Rlim.

What is the accuracy for my Rlim value?

Regards,
Matteo Silotto

  • Hi Matteo, 

    Thanks for reaching out on E2E!

    Unfortunately, we do not have accuracy data for the specific case of RILM = ~250Ω. However, I'd like to mention that the accuracy at 250Ω will be better than the accuracy at 400Ω, which has roughly a 25% in current limit accuracy. Therefore, I'd expect the accuracy of the current limit at 250Ω to be approximately between 1.5A and 2.5A.

    Thanks,
