TPS22810: TPS22810DRVR PCN for MSL-2 to MSL-1

Junichi Komura

Part Number: TPS22810

Hi TI engineer,

I'm Junichi Komura of techinal support staff in Tokyo Electron Device.
We have question about TPS22810DRVR MSL update as MSL-2 to MSL-1.

Becasue our customer(NEC) received two types of MSL-1(DC:2137) & MSL-2(DC:2114) reels.
Latest datasheet has been updated MSL-1(on 28-Sep-2021),
but we have not received any PCN/Notification yet.

Due to inform this change to our customers(NEC and others),
we want to know when TI issus PCN for this update.
Or any advices please let us know.

Thanks and best regards,
J.Komura@TED

Hello Komura-san,

CDAT ran a qualification for this material set and confirmed that they could meet MSL 1 and so were able to relax from MSL 2 to MSL 1. Since this does not require any additional handling requirements we typically do not issue a PCN for this type of change.

Burmside-san,

Thanks for your replay and update information.

Even we see that changed MSL-1 is relax condition, how about relationship between J-STD-046.

According to this jedec-046, Drypack requiremet may require customer notification.

Does it clear this requiremet?

And "no drypacking", it is easy to find diffrence by customers.
I think we need to notifiy this our customers.
So would you please give comment or advice for this.

Thanks and best regards,

Komura-san,

The dry pack requirement is based on MSL down grade which requires PCN notification. It's not based on a MSL upgrade. Since MSL-2 has a 1 year floor life, and it's been upgraded to MSL-1 which has an unlimited floor life, no notification is required. If you have anymore questions about this please feel free to reopen this thread.
