Part Number: TPS629203

Hi team,

Customer is asking about for example 27kohm is allowed which is out side of E96, how this impact?

Hi NY,

If using a resistance outside of E96 you may select the wrong setting from the MODE/S-Config table. We recommend using 1% and 200ppm/C or better to ensure the correct mode is selected.

Thanks,

Joseph

the teble shows 27.4kohm, but customer want to use 27kohm. is it acceptable?

Since 27kohm is a standard 5% value there may be too much tolerance in the resistance to cause a different mode to be selected.

We recommend using a 1% 27.4kOhm resistor.

Thanks,

Joseph

Hi Joseph, sorry for additional confirmation, if 1% 27kohm, is it acceptable?

Hi NY,

To ensure the correct mode is selected we still recommend using 1% E96 resistors of the values listed in the datasheet table for Smart Configuration.

If these values aren't used, then the customer should verify it for their application, as 27k 1% is not a standard 1% value we have available to test.

Thanks,

Joseph
