LIS2DW12 SA0 Pull-Up

Question asked by Borja Martinez on Aug 24, 2017

I have a design in which I have to put the line from SA0 to GND (this is mandatory since the alternate I2C address is already used on my I2C bus). However, the internal pull-up of SA0 seems like it can not be disabled, implying that my system will always have an extra power consumption of around 100uA@3V. How can this be avoided?

 

It is shocking that in other devices of the family, such as the LIS2HH12 that I used before in my design, it is possible to disable the pull-up by software. Why has this feature been removed?
