Part Number: UCC21520

Dear Specialists,

My costomer'd like to know the difference between Rev. D and Rev.E.

PCN states features and tpwd have changed from Rev.D to Rev.E.

But they don't have old version(Rev.D), so could you please provide the datasheet of Rev. D.

Or could you please let us know which contents of Features have changed and the value of tpwd in Rev.D.

I appreciate your great help in advance.

Best regards,

Shinichi

Hello Shinichi,

Thank you for your inquiry, we have updated the datasheet to reflect accurately the device specifications of PWD. The functionality of the device is not impacted by this change. You will see the device is now matching the UCC21520-Q1, which is the same design but with additional automotive qualification.

Regards,

Krystian

Hi Krystian,

Thank you for your reply.

I understand the reason for the data sheet change.

The customer wants to know how the value of tpwd has changed.

Otherwise they won't know if they can continue to use this device.

I found a Rev.C datasheet on the web, tpwd is 5nsmax.

I understand tpwd is changed from 5nsmax to 6nsmax in Rev.E, is it correct?

I appreciate your great help and cooperation.

Best regards,

Shinichi
