Hi Team,

Good Day.

For this part"TPS6287B25LA0WRZVR"

datasheet"https://www.ti.com/lit/gpn/TPS6287B25"

ultra link"https://vendor.ultralibrarian.com/TI/embedded/?gpn=TPS6287B25&package=RZV&pin=24&sid=lite19ed390e19ed390e19ed39063f60c725c094f74&c=1"

Please advise for pin 19 and 20 as mentioned on utltra link as SDA or VSET4 for pin 19 and for pin 20 as "SCL or VSET3", however in datasheet pinout table page 5 not clear these functions found in some part or not as clearly mentioned for pin 3 for example contains fset if part TPS6287BxxJE2WRZVR.

but for pin 19 and 20 no such information mentioned, however in page 3 mentioned something on these pins but also for parts have v suffix will have vset3,and vset 4 and no sda or scl , however mentioned in datasheet title all series have i2c interface

Thank you.

Hi Mark,

I checked datasheet again and the pin19 and 20 are SDA/VSET4 and SCL/VSET3. Can you explain with more details what are the discrepancies on the ultra librarian?

Thank you and best regards,

Jingyi
