UCC23313: UCC23313DWY and UCC23513DWY marking issue

Part Number: UCC23313
Other Parts Discussed in Thread: UCC23513DWY

Hi E2E team,

As for UCC23313DWY and UCC23513DWY, they have the same device marking 'UCC23513'.

and it looks like both devices have different performance.

Customer compare with 2 chips, because of same marking, he cannot check which one is 233113 and which one is 23513

Can you please let me know the reason why same marking?
How can distinguish?


if he dont have original label when producing in the line, how to distinguish for both tube packing?

Thanks.

Regards,
