Figure 7. Switching Circuit with Example Layout
Another important layout detail is the connection of the sense resistor. Proper Kelvin connection layout should be
used to ensure the signal quality viewed by the sensing circuit inside the DS2715 is adequate. Figure 8 shows a
recommended connection of the sense lines to the resistor footprint.
