Required Current Consumption details of LIS2DW12TR for 3.3VDC

Hi Sir/Mam,

For our design which operates at both 1.8VDC and 3.3VDC and we use the sensor with part number LIS2DW12TR. We require the current consumption details for 3.3VDC,

in datasheet we found the current consumption values only for 1.8VDC.

So please provide current consumption values for 3.3VDC for both at Active state and Sleep state.

Regards

Vinodh

    Hi Vinodh @VKuma.9​ ,

    please note first that the current consumption at 3.3V is not a datasheet parameter, so we as ST can only indicate a range coming from bench / characterization tests.

    From these, in first approximation you can consider more or less an average +30% increase of current consumption at 3.3V with respect to the 1.8V data on LIS2DW12, for both at Active state and Sleep state.
