MMPF0100 I2C Programming

Hi Community,

 

Recently, I've received MMPF0100 parts with default configuration.

 

I need to change some outputs to use them with my custom i.MX6 board. Specifically, I need

- 1.35V from SW3 instead of 1.5V default value

- 1.2V from SW4 instead of 1.8V default value

- 2.5V from VGEN4 instead of 1.8V default value

 

And most importantly, I need these changes to be permanent.

 

I am very confused about this issue. Do I need OTP feature in order to achieve this or can I do this on-board with just normal I2C operation?

 

Thanks.
