In order to dissipate sense-resistor heat from large
sense currents, solder the RS+ and the RS- pins to
large copper traces. Keep the part away from other
heat-generating devices.
For accurate measurement of V
method is recommended. The current into RS+ and RS-
is only a few microamps; therefore, a short distance from
RS+ and RS- pins does not cause significant errors. It is
recommended to keep the value of R
higher than the values of the trace’s resistance.
