APPLICATIONS INFORMATION (CONTINUED)

CS+, CS-

Select a resistor value that will drop no more than

100mV (full scale) when full load is drawn by the

converter or circuit being sensed by the resistor RS

(Figure 1). To obtain highest accuracy current-

sensing, provide a Kelvin connection from the resistor

to the CS+ and CS- pins. Do not allow the main

current path circuit traces to inadvertently become a

part of the current sense resistor. Kelvin connect

directly at the resistor and follow the manufacturer’s

instructions for exact positioning of the traces for

Kelvin sensing.
