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 R
S
(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.
