Current sense resistors enable
the measurement of current
flow in a circuit by monitoring
L
a voltage drop across a pre-
cisely calibrated resistance.
LVK25
The LVK chip features four
(2 watt)
terminals, also known as a
W
“Kelvin” configuration. This
configuration enables current
to be applied through two
opposite terminals and a sens-
ing voltage to be measured
across the other two terminals,
t
eliminating the resistance and
a
temperature coefficient of the
terminals for a more accurate
b
current measurement.
