TDP158: voltage range of SDA_SRC

Part Number: TDP158

Dear team,

Is there any rick if I follow SDA/SCL_SRC design with TDP158EVM?

There is a pull up resister to BOARD_5V at SDA/SCL_SRC bus. But the absolute maximum voltage of this two pins are only up to 4V in our datasheet.

Did I need level shift IC to meet datasheet recommend or just  follow  EVM schematic is good?

Thanks.

Ben

    This is a mistake in the schematic, they should be pulled up to BOARD_3P3V, not BOARD_5V.

    Thanks
