TPD12S520: ESD protection testing

Peter Findlay

Part Number: TPD12S520
Other Parts Discussed in Thread: STRIKE

Hi all,

I'm trying to identify whether I need to perform transient voltage testing on two different components as part of a Lightning Strike Protection test scheme or whether I can provide justification for not testing this functionality based of off TI's quality control for the parts.

The parts in question are:

TPD12S520DBTR Single-Chip HDMI Receiver Port Protection and Interface Device

TPD12S521DBTR Single-Chip HDMI Transmitter Port Protection and Interface Device

What I would like to know about both parts:

What type of quality control does TI perform to ensure the ESD protection works, especially the transient voltage suppression aspect? I.e. is it a batch sample, every component, etc?

What size pulse (pulse width, pulse peak, etc) would be needed to non-destructively test that the ESD protection is there?

Best regards,

Peter F.

Hi,

When TI develop the new device, the device will doing different test and variations to make sure the device performs is within SPEC .

Hi Michael,

Once development has finished does TI do any checks on the manufactured parts to ensure ESD functionality?

Hi Findlay,

TI will take some of the product to test the ESD function to ensure it within our SPEC but not test every chip.

The ESD function will guarantee in the datasheet.

Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
