Using LIS3DH direct from coin cell unregulated pow...

Posted on March 15, 2016 at 17:48

The LIS3DH works from 1.8V to 3.6V.

If I use it direct from a CR2032 coin cell w/o regulator, will there be any side effects as the voltage drops from 3.3V to ~2.2V?

For example, will the calibration drift substantially?

Is this something that I can adjust for in FW?

If other devices on the same VCC cause the VCC to drop 0.1V to 0.2V over ~ millisecond, can this cause false triggers on the LIS3DH?

I am not using the ADC, only the accelerometer.

Thanks
