TPS7A02: YCH package pin 1 marking

Hey Darren, 

My apologies this is not something that we can verify, but our counterfeit team and customer support center can help!

Please follow the following instructions:

1. Completed Counterfeit Request Form. 
2. High quality pictures of the bottom & top of the device(s)
3. High quality pictures of the 2D bar code labels.  
4. Copies/pictures of shipping documents, i.e. packing slip showing the origin of the devices to TI.  (If this information cannot be provided we are unable to provide verification due to uncertainties regarding chain of custody of the products.) 
5. Provide device application.

Also note:

Semiconductor products purchased outside of TI’s authorized distribution network, including through brokers, independent distributors, or online marketplaces (sometimes referred to as the “gray market”), may be counterfeit, modified, beyond TI’s recommended shelf life, or improperly stored or handled. Accordingly, TI does not provide warranty coverage or customer support for semiconductor products purchased outside of TI’s authorized distribution network.

I hope this helps!

Thanks,

-Jimmy

Hi Jimmy,

My question is just about what the pin 1 marking looks like so the customer can orient the part properly.  The drawing makes it look like pin 1 is marked with a shaded square.  The image from the customer looks like small line.

Just to be clear, you are recommending I submit this as a counterfeit device verification and that team will be able to answer this question about pin markings?

Thanks,
Darren
