Hi Poki,

Can you please re attach the Layout files. 

I don't see it attached. Can you help understand more information in regards to the target size ?

Is there anything specific you like to us to check in the layout ?

Hi Poki,

I wanted to make sure that we are looking at different threads. There is already thread that is ongoing. Is this a different topic ? it appears to be around the same topic.

Hi Arjun:

The question I ask you is about the SCH review and the https://e2e.ti.com/support/sensors/f/1023/t/905900#pi320995=2 is talking about coil design

But YES it's the same topic

Hi Poki,

The schematics looks OK but a few questions here.

The I2C lines are connected to a 2.1V supply is that right ? This is Ok as the I2C lines 3.3V I/O Capable. 

Can you please comment more on the LPWRB signal ? I cant tell if this is tied to uC. What is the voltage levels on this. Please ensure that its within the ratings of the supply as per the datasheet. We recommend that the LPWRB signal is also tied to a 1.8V Logic signal.
