VDD for BMM150

[mike1974]

I have a question about VDD for BMM150.

The recommended VDD for BMM150 is 2.4V, but I want to use VDD at 1.8V.

Will this affect the sensitivity and accuracy compared to using 2.4V?

If so, how much will they be affected?

Hi,

Thanks for your inquiry.

BMM150 has power supply range VDD from 1.62V to 3.6V and VDDIO from 1.2V to 3.6V. This means that users can power BMM150 with VDD/VDDIO of 1.8V, 2.4V, 3.0V, 3.3V, etc. or different VDD and VDDIO as long as they are in their ranges. There is no difference from the performance point of view using different VDD and VDDIO because there is internal LDO inside BMM150.

Thanks.
