Part Number: TPS55288
Other Parts Discussed in Thread: TPS65988,

My MCU is connected to I2C2 of TPS65988, and I2C1 of TPS65988 is connected to TPS55288. How do I program TPS55288?

For example, change the OCP of TPS55288?

thanks

Hi Sir,

You can read TPS55288 datasheet.

The MODE pin resistor decides the I2C slave address (In table 7-2).

The datasheet also lists all registers setting in part 7.6.

Hi Zack Liu，

My TPS55288 I2C is not connected to the MCU, but to the TPS65988, so I cannot directly operate the TPS55288 through the MCU's I2C. Can I write to TPS55288 through TPS65988?

thanks
