Could open drain pin of I2C from MMA7660FC drive 2k2 resistor at 3.3V?

I do not found in datasheet the maximum current this pin can drive and it is only suggest to use 4k7.

Hi Michael,

Yes this is fine. Changing the pull up resistor value from 4.7k to 2.2k does not change the offset or noise.

Check page 55 of the UM10204: I2C-bus specification and user manual
