PCB Layout Recommendations:

Figure 22 - Recommended PCB layout for measuring across the sense resistor (R1).

PCB Layout

The pc board layout shown in Figure 22 is representative of

the proper board layout for the most accurate current sensing

by the PI2211. The sense line are connected to the internal

centers of the sense resistor's pads, minimizing the added

resistance of the receiving copper.

Grounding for the PI2211 should be done using either a low

current ground plane or a local ground plane, contacting with

just the PI2211's ground pins and external components; then

connecting this plane to the system ground at a single point. It

is not recommended connecting the PI2211's ground pins and

external components to different ground planes or to high

current ground planes.
