Part Number: LM5010

Tool/software:

Currently using 14 pin LM5010AMH IC in SMPS for switch system in battery management system.

Currently seeing external noise / transients breakover an interlock coil and onto an internal 12V supply line.

Noise results in damage to the LM5010AMH IC.

Looking for support for circuit review to ensure we are using LM5010AMH IC correctly or establish any recommendations to mitigate noise impact to IC.

Hello Brian

Please share the schematic and the completed quick start excel file https://www.ti.com/lit/zip/snvu087 for my review.

And please send me the board pictures, and if possible, please identify which pin is damaged.

I will be out of office and I will not be able to reply this E2E post anymore.
