All contributions to the kicad library must follow the KiCad library convention

Thanks for creating a pull request to contribute to the KiCad libraries! To speed up integration of your PR, please check the following items:

  • Provide a URL to a datasheet for the symbol(s) you are contributing
  • An example screenshot image is very helpful
  • Ensure that the associated footprints match the official footprint library
    • A new fitting footprint must be submitted if the library does not yet contain one.
  • If there are matching footprint PRs, provide link(s) as appropriate
  • Check the output of the Travis automated check scripts - fix any errors as required
  • Give a reason behind any intentional library convention rule violation.

  • The NC-Pin should be on the symbol outline (KLC S4.6)
  • Description should be comma-separated, please add the package-name to the description. The package-name should be the latest item in the list
  • Description is wrong, its a quad-channel device
  • You can add infos like 0.7pF or 0.5nA leakageto the Description
  • Pin-Number should not be part of the footprint-filter

  • Default FP DCK should be Texas_R-PDSO-G6 (also adjust the filter)

This is a standard MO-203AB / SC-70-6 / SC-88 / SOT-363 package.

https://www.jedec.org/sites/default/files/docs/MO-203C.pdf

Currently, both Texas_R-PDSO-G6 and SOT-363_SC-70-6 FPs are wrong.
How about fixing SOT-363 and going with that one, @cpresser?

@Doeme next time, please do not force-push. It you just add a commit on top instead I can review the changes more easily.

@chschlue I agree. As of now, I don't have access to JEDEC documents yet to verify. Having a non-manufacturer specific footprint sound great. Afaik it should be possible to script it with the existing ipc_gullwing_generator.py

Something with the part-numbers here is wrong.
In your first post the link goes to TPD4E1B06 which is a quad device.
The symbols also indicate a quad device.
But the datasheets in the symbol point to tpd2e2u06and tpd2e2u06 which are both dual channel devices.

I take it there is currently no way to get SOT FP names right?

Well read the readme of the generator. It includes an option how to get a footprint name differing from the default.

There should not be a datasheet link in the symbol, because checklib.py explodes if there is (KLC S6.2)
I think the editor adds it automagically, and probably botches that (which is a pain since I have to delete it every time I save the library)

@Doeme next time, please do not force-push. It you just add a commit on top instead I can review the changes more easily.

Understood.

The data-sheets should be properly set. Add them in in the .dcm file. See here: KiCad/kicad-website#446

@Doeme are you still alive on this subject ? an you solve the branch conflict please to continue the review ?
@cpresser I see several issues on these symbol+travis errors to be fixed, I can have a look and suggest modification if you want

Hello, yes, I'm still alive and well. I'll merge the master shortly.

Thanks, just ping when it is ready for review
@cpresser do you want to continue on this one ?

@myfreescalewebpage It would be nice if you can this one over. Its not as simple as my other open PR. And I rather concentrate on footprints.

@Doeme full review below:

TPD4E1B06DCK

  • Description should ends with the package name, please add , SOT-363 at the end

TPD4E1B06DRL

  • Where have found SOT-5X3 is SOT-563 ? I don't think this is a wildcard of TI. I think the footprint should be Package_TO_SOT_SMD:Texas_DRL0006A (not available in the lib) and the fp filter in this case: Texas*DRL0006A*
  • Description should ends with the package name , Texas DRL0006A

Done, thanks!

Where have found SOT-5X3 is SOT-563 ? I don't think this is a wildcard of TI. I think the footprint should be Package_TO_SOT_SMD:Texas_R-PDSO-G6 (available in the lib) and the fp filter in this case: TexasRPDSOG6

Please see #2256 (comment) :

Currently, both Texas_R-PDSO-G6 and SOT-363_SC-70-6 FPs are wrong.

Hence "Package_TO_SOT_SMD:SOT-363_SC-70-6" should be right.

Sorry I haven't read all comment. I compared the sizes between the datasheet and the SOT-363 in the lib, and SOT-363 is too large for this device. The Texas R PDSO G6 is also too large too. In fact the proper package for this should be "Texas_DRL0006A" which need to be submitted because it is not in the lib. You can use the generator for this.

ah, yes, I confused the two ics. remind me to do two pull-requests instead of one next time, differentiating between those two gives me massive headaches.

see the footprint pull request here KiCad/kicad-footprints#2485

lool yes me too at the beginning I confused the two !
It's generally better to have two pull requests. And for the reviewer it is also better because we can review one. Merge. Then review the other one and merge. Particularly when a single symbol block the PR because of missing footprint.
Will review the footprint asap.
