LIS3DH - Power Consumption

[BToft]

Dear Forum. 

I use a LIS3DH connected with a Pic mainboard. I cummunicate with I2C and have set it up with interupt. I use 8mg, Lowpower and 50 hz odr. 

I have a problems with Power Consumption. Before i insert the LIS3DH it use 3 microampere. After i have set it up with interupt i use 100 microampere. We use a STEVAL-MKI105V1 eval board. 

How can i set it up so it only use 10 micro ampere. 

 

 

 

Best regards

Hi @BToft ,

That's sound strange LIS3DH in LP mode and ODR 50Hz should have a power consumption of 6uA. Can you share your schematic?

Hi @BToft ,

Can you try to connect also SDO and CS according to the datasheet?
