Part Number: TPD5S116

Hi team,

Could you team me how to connect 5V_SYS, 5V_CON if I don't use the load SW_? Can I leave it open or connect to GND?

Also, could you let me know the max. and min. values of pullup voltage of SCL_SYS, SDA_SYS?

Hi Zeming,

The 5V_SYS should be the source of the internal 3.3V, so you may need to input it.

The max and min values of pull up voltage of SCL_SYS, SDA_SYS should be 1.1-5.5V

Best Regards,

Kuno

Hi Kuno,

Thanks for your answer!

Sorry, I wanted to confirm the pullup resistance of SCL_SYS, SDA_SYS, not voltage.

Typ. value is 5kohm, but no min and max values. If you cannot give an exact value, approx. range is okay.

Zeming

Hi Zeming,

Sorry, I can not provide the min&max value, I check the Starfish website, but this device is too old, so I can not find anything in the Starfish, and the designer also leave TI, so I can not ask someone for help, sorry.

Best Regards,

Kuno
