LM5069: Excel Tool

Part Number: LM5069

Dear Team,

If we input smaller than 2mohm for Rs, the RCL1 and RCL2 will show NA.

What is the reason?

Is it because when Rs is too small, we are not recommend to divider the Rs voltage anymore?

    Hi Kevin,

    When using an external resistor divider, Rs must be larger than the F37 value. Pick the next larger available Rs.

    When not using an external resistor divider, pick the next smallest available sense resistor.

    If you still face issue, please share the design excel

    Best Regards,

    Rakesh
