Part Number: TPS25750
Other Parts Discussed in Thread: BQ25792,

We have a UFP application of TPS25750D+BQ25792, which needs to be able to identify SDP (computer) and 5 PDO'S (5V/3A, 9V/3A 12V/2.5A 15V/2A 20V/2.25A).
Can we use the MCU to read the 0X3F data of the register from the TPS2570D to set the Input current limit of the BQ25792?

The TPS25750 Will automatically handle configuring the BQ25792 for all 5 of your sink PDOS and the SDP case.

If you need to access the BQ25792 to override any of the TPS25750 settings, you can utalize the I2Cr and I2Cw commands listed in the TPS25750 Host Interface Technical Reference Manual
