TPS25982: if OCP equation is with high/low temperature compensated?

Hi Ann,

This equation tells typical value at 25C. There will be variation at 25C and other temperatures also.

Hello Kunal,

Thanks for your reply! Customer's question is that do we use MOSFET RDSon to sense the current? If yes, than temperature will influence much on current sensing. If no, could you kindly let us know how do we sense the current? Thanks a lot!

Best regards,

Hi Ann,

Sorry did not get your question. Do customer want to verify current limit on their board? They can use a current probe to measure input current.

Hello Kunal,

They would like to know the way TPS25980 sense the current. May we know if TPS25980 sense current from MOSFET Rdson or sense current from current sense circuit on the current path? Thanks a lot!

Best regards,

Hi Ann,

What is the concern of customer for asking this question? As I have told earlier ILIM value can vary with temperature.
