TLV3502: & TLV3502-Q1: are these the same device?

Nicholas Carley

Part Number: TLV3502

Hello,

I just want to confirm that these two devices (TLV3502 & TLV3502-Q1) are the same silicon, the Q1 just has additional testing for the automotive qualification.

Thanks,

Nick

Hi Nicholas,

the Q versions and the non-Q versions not necessarily see the same fabrication process and sit on the same wafer. I would not rely on that they are "the same silicon" as you say.

Hello Nicholas,

Yes, they both use the same die revision, fab code and die sizes, though the die ID are slightly different (this is not unusual for Q1 devices - as Q1 devices are tracked differently), so I cannot say they are exactly the same - but they seem to be.

The assembly flow and package BOM are slightly different, as is common with commercial and Q1 sister devices. I cannot get into the differences in a public forum.

Functionally and electrically, they are identical.
