MP6519- ISEN resistor values

I’m trying to use the MP6519 for an motor application. I looked thought the datasheet and EVA baord schematic.
I’m trying to find out how to calculated the ISEN Resistor value. (R11 on the eva board or R4 on the datasheet). There’s not documentation on how this value are determined.
It would be helpful, if it was include in the datasheet.


Hi Situ,
Welcome to the forum.
The ISEN resistor is same as the feedback resistor which is mentioned as Rifb in the Datasheet. You can calculate the according to the power loss formula given in the datasheet.
Let me know if you have more questions.
