DP83869HM: Test data for latch up

Hi Noriyuki,

Can you clarify what you mean by latch up? Are you referring to timing requirements? Is this with regard to failure after an ESD event?

Thanks,

Lucas

Lucas,

Sorry for late reply.

This is for failure after an ESD event.

Hi Noriyuki,

The PHY is tested based on the IEC 61000-4-2 standard. You can refer to section 8.2 of the datasheet for information on ESD ratings.

Thanks,

Lucas

Hi Lucas

Latch-up test is different with ESD test as below app note. Could you confirm again whether TI has the data for latch-up test? Customer wants the date for the latch-up test.

Hi Noriyuki,

Which standard and test are you asking for? Under what condition do you want latch-up? Latch-up test is part of our ESD testing, which can be found in section 8.2 of the datasheet.

Sorry for late response.

Are there any date about JESD78 that is the standard of latch-up testing?

Hi Noriyuki,

I am looking into this test standard and will be able to provide additional feedback by tomorrow.

Thank you,

Nikhil,

Looking at Quality, reliability & packaging information of the device, it seems that DP83869HM could pass JESD78. Is this true? Could you confirm this?

If this is true, could you confirm which pins are tested for JESD78?

Regards,

Noriyuki Takahashi

Hi Noriyuki,

Thank you for the eply.

As mentioned above, We do not perform the JESD78 testing.

Sreenivasa,

You can see one DP83869HM passed the latch up test as the attached below.  You can see this from the link as below. How should I understand this?

Hi Noriyuki,

Thank you for the table. This could be an internal qualification test but not specified in the datasheet as seen in the table you have sent.

Sreenivasa,

Could you confirm which pins are tested for JESD78?

Regards,

Noriyuki Takahashi

I mean, do you have supplemental information for the test?

Regards,

Noriyuki Takahashi

Hi Noriyuki,

We do not have the data that that could be reviewed and provided. Could you please provide some additional inputs on the use case ?
