TPS65185 and I2C

From the datasheet I understand that it shouldn't be necesseray to implement I2C to use this product.

It this correct?

    Hi Olof,

    The Global State Diagram (Figure 24 of the datasheet) shows that the device can transition to different modes without i2c, where the device would operate with the default values indicated in the reset row of the individual registers.

    So technically i2c would not be "necessary" if the default settings work for your application, but omitting the communication capabilities of the PMIC drastically limits the versatility of the device, and may make debugging efforts and application specific adjustments more difficult to implement later on.

    Hi Richard,
    Thank you for a clearifying answer.
    We are in a bringup-state so we just want to see that we can send something to to the EPD in our custom build.
