Are we communicating with MP6631H using the I2C protocol?

Hi Team,

When I examine MP6631H’s datasheet. I see the register tables but it does not say how I should communicate with these registers. When I look at the schematic of the Eval boarrd, I see FG/RD/SCL and PWM/DC/SDA pins. Is there a more detailed documentation? Why are the locations of SCL and SDA pins not written in the datasheet?

Hi Cem,

The MP6613H does not use i2c to communicate. Communication pins used are PMW/DC, FG, DIR, and BRK.

The programmable registers are only one time-programmable from our factory. To setup these registers, please reach out to MPS NOW Remote Support - Support (
