DRV8412: The changes of footprint?

Benyuan Liu

Part Number: DRV8412

We purchased a reel of DRV8432DKDR (75 pcs) from a local retailer, and we faced similar problems as this thread:

DRV8432： Appearance changes? - Sensors forum - Sensors - TI E2E support forums

In the 8432EVM we bought, it is like the picture 1 of the previous thread, where there is a black dot with strips indicate pin 1.

In a recently purchased DRV8432DKDR, the pin 1 indicator is a black dot on the back, it is exactly like picture 2 of the previous thread.

The silkscreen is 91ZTH64G4. Is there any problem with this reel? How could I tell the production month, year from this bulk?

Benyuan,

In a prior thread, I sent the link from TI on approved vendors. Did you purchase this thru approved channels?

In parallel, I can run the lot trace code.

Ryan

Benyuan,

That is a valid lot trace code. First 2 digits are YEAR and MONTH...so assembled in January 2019.

Pin 1 indicator is white dot on top.

Snippet from datasheet.

Regards,

Ryan

Thank you! We purchased these from a local retailer (not the official one on the TI website) as a backup. Our product was still DRV8412 and DRV8432 based, and we will evaluate DRV8962DDW or DRV8962DDV when it is available.

I will try to reach local TI retailers.

What about 24Z001EG4, is it a valid lot? How could I tell it is fabricated in 2012 or 2022?

Benyuan,

I can't find that one. If it was valid, it would be a 2022 manufacturing date.
