Current Sensing.
To minimize inaccuracies caused by
ground-trace IR drops in sensing the output current level,
the current-sense resistors (R
S1
and R
S2
) should have an
independent ground return to the star ground point. This path
should be as short as possible. For low-value sense resistors,
the IR drops in the printed circuit board sense resistor traces
can be signi
fi
cant and should be taken into account. The use
of sockets should be avoided as they can introduce variation
in R
S
due to their contact resistance.
The recommended value of the sense resistor, R
S
(
), is
given by
R
S
= 0.5 / I
TripMAX
up to a maximum of 1
for I
TripMAX
of 0.5 A. Below 0.5 A,
R
S
should be 1
, and V
REF
reduced accordingly, as shown
in the following table.
