MAX4072 Maxim, MAX4072 Datasheet - Page 13

• Manufacturer Part Number: MAX4072
• Description: The MAX4069–MAX4072 low-cost, bidirectional, high-side, current-sense amplifiers are ideal for monitoring battery charge and discharge currents in notebooks, cell phones, and other portable equipment
• Manufacturer: Maxim

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.
