LIS2DH12TR- Not working on 2.9V and above voltages

[Smalik]

Hello,

I am using LIS2DH12TR through SPI but I am not able to operate it on greater than 2.8V. On greater than 2.8V I am not able to read the device ID. But according to the datasheet, it is able to operate up to 3.6 V. SO how can I use this ic greater than 2.8V?

Any help would be appreciable

Thanks and Regards

Hi Sarthak Malik @Smalik​ ,

Are you using the Vdd and VddIO together?

Hello Eleon @Eleon BORLINI​ 

Sorry for the delayed response actually the Diwali holidays were going on that's why I am unable to reply.

Yes, I am using the Vdd and VddIO together.

Thanks

Hi Sarthak Malik @Smalik​ ,

sorry for the delay in my answer. The parts should have no issue in this sense, since we never encountered this kind of limitation and they are tested 100% at 3.6V. Which is precisely the condition you are operating? Is the application processor capable to read at that voltage? Could you try also to lower VddIO with respect to Vdd?

Hello Eleon BORLINI,

Yes, the processor is capable to read the 3.6V and we have other sensors as well on the same board which is working on 3.3V. and we can not try to use lower VddIO because it is by default short by the Vdd in our board.

Thanks

Hi @Smalik​ ,

you might try another part if this one is not working.

Helo Eleon @Eleon BORLINI​ ,

Thanks for the update. Is there any problem related to this part? Because I have manufactured 100k boards by using this IC. Please provide me with the correct resolution.

Thanks

Hi Sarthak Malik @Smalik​ ,

due to the volume you are reporting, I just escalated the case to OLS so that you can get a broader support on this issue.
