Part Number: TPS65235

Hi Experts,

Our customer is asking some specifications about TPS65235 I2C interface, can you help to check them?

1. Do we have a built-in Schmitt Circuit for noise suppression on I2C interface?

2. Can we share some more details about this device's block diagram for I2C interface?

Thanks.

    Hi, Jacky 

    1. I think there is shaping circuit for all of digital IO pins, it should have built-in Schmitt Circuit for for noise suppression. I will double check with designer. 

    2. What information do you want to know about the block diagram for I2C interface? 

    The I2C interface in TPS65235 is designed according to the standard I2C bus Specification, Version 2.1, January 2000. So i think you can find the block diagram information in its Specification.

    Hi Zhao,

    Regarding to question 1, please help to double confirm with designer and give us the feedback ASAP, as customer is requesting for this urgently.

    For question 2, we need the block diagram similar to other devices like TAS5756's datasheet description as below, please help to provide it.

    Thanks.
