Original question:

TPS65982: TPS65982 FW issue

TPS65982: I2C master error in datasheet

Part Number: TPS65982
Other Parts Discussed in Thread: TUSB1046EVM, TPS65987D

Hello.  I have purchased the TUSB1046EVM and am trying to use it to drive a portable USB-C monitor.  It appears that the I2C Enable Mode is not working.  In response to Tim Liu's question, you say that the TPS65982 does not have the ability to be an I2C master.  This statement is in conflict with datasheet section 9.5.2 paragraph 2 that states "The first two ports can be a master or a slave, but the default behavior is to be a slave."  If the datasheet is incorrect, please revise it.

Thanks,

David

    Hello David,

    Thank you for sharing. If you are interested in a single port PD controller with I2C master capabilities, I recommend using the TPS65987D. We are recommending that all of our customers start to make the transition to this device anyways as this is our latest single port PD controller
