LM5101C: There is no Part name on the package.

Part Number: LM5101C


I try to work LM5101C but it doesn't work.

I doubt if the part is really LM5101C or not.

I found on the package " MJAB SXDB".

Is it really LM5101C?

  • Hello,

    Thank you for the interest in the LM5101C. I reviewed the datasheet package option addendum in the LM5101C datasheet.

    In the device marking column for the MSOP power pad package there is listed a device marking of "SXDB" for the LM5101CMY.

    So it looks like this could be the marking for the LM5101C if it is the MSOP package.

    When you say it does not work, can you explain the test conditions and behavior?

    Make sure VDD is 9 to 14V, HB-HS is 8 to 14V, HI and LI inputs are from 0V to > 2.4V pulse signal.

    Did you receive the parts from a known reliable source?
