Question

h3lis200dl consumes too much power.

When I used the IIC communication mode of h3lis200dl, I connected the 7th pin SDO directly to the ground. Since the SDO pin has a pull-up resistor inside, the current is too large (about 60uA). I would like to ask if there is an unopened register to connect the SDO Is it closed? The product has been sent to the customer and the hardware cannot be changed. I hope someone can help answer it as soon as possible.

Hi @Phoenix1 ,

I don't see anything critical in your schematic.

Probably the increase in current consumption is due to the SCL's internal pull-up.

We have verified the current consumption in the circuit.
