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​ ,

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.

Hi Sarthak @Smalik​ 

You should have received a feedback on your email.

I'm report here for simplicity:

Hello Sarthak,

There's no issue for LIS2DH12 to operate from 1.71V to 3.6V. For your particular issue, I suggest to look into:

1) The logic voltage level of the GPIO(SPI) of the host controller meets the VHL level of LIS2DH12 (Section 2.3). Please share the SCH to us to review.

2) Please make sure the CS, SPC, SDI/SDO are comply with the timing spec as listed in Section 2.4.1. Please let us know the clock frequency you are running too.

Thanks
