Dear Sir,

Would you pls share TPS3431 EN Pin internal pull up resistor value?

Thanks, Ian.

    Ian,

    I believe the resistor value is in the Megaohms range. I looked through the information I have available and I didn't see a specific resistor value so I used the internal reference voltage that powers the internal ENABLE block and the Enable pin current when V_Enable is 0V.

    This calculation gave a value of 4 Mohm. This is not something we can guarantee however. Can you explain why the resistor value is needed? I can look to add something to the datasheet if its absolutely necessary.
