TS5A23166: Ron flat values

Giorgia Navarra
Intellectual 1271 points
Part Number: TS5A23166

Dear e2e team,

Starting from the definition given in the datasheet (https://www.ti.com/lit/ds/symlink/ts5a23166.pdf?ts=1659951690649&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FTS5A23166%253FkeyMatch%253DTS5A23166%2526tisearch%253Dsearch-everything%2526usecase%253DGPN):

ron (flat) is the Difference between the maximum and minimum value of ron in a channel over the specified range of conditions and analyzing the data

I see that in the table 6.8 at pag 9 under the same conditions (Vno, current and temperature), the maximum Ron is equal to 4 ohms but the maximum difference between minimum and maximum Ron is equal to 27 ohms (full case temperature range). Similar consideration for the data at 25 ° C: maximum Ron of 3.9 ohms with a maximum difference between Ron min and Ron max of 22 ohms. 

It seems that Ron flatness data refer to Rpeak and not to Ron.

Could you help me to understand how to read this table?

Thanks,

Giorgia
