Part Number: TPD5S116

Hello,

Regarding to pull-down resistors on CES_SYS,SCL_SYS and SDA_SYS pin on TPD5S116,

my customer is asking a question.

(Question)
When EN=0, are CES_SYS,SCL_SYS and SDA_SYS pin pull-down ?

Hi Tao， These pins are IO pins，there will be uncertain state if EN=0. Best regards, Ansel

Hello Ansel,

Sorry for delay.

My customer has some question.

(1)When EN=0, is it possible to be high on SYS pin side by internal pull-up resistor?

(Will these resistors work as pull-up at EN=0?)

My customer has a concern that SYS pin side will be uncertain state if EN=0.

(2)Do you have any solution to avoid uncertain state on SYS pin side at EN=0?

Regards,
