Description

The FAN4010 is a high-side current sense amplifier

designed for battery-powered systems. Using the

FAN4010 for high-side power-line monitoring does not

interfere with the battery charger’s ground path. The

FAN4010 is designed for portable PCs, cellular phones,

and other portable systems where battery / DC power-

line monitoring is critical.

To provide a high level of flexibility, the FAN4010

functions with an external sense resistor to set the

range of load current to be monitored. It has a current

output that can be converted to a ground-referred

voltage with a single resistor, accommodating a wide

range of battery voltages and currents. The FAN4010

features allow it to be used for gas gauging as well as

uni-directional or bi-directional current monitoring.

must be taken not to exceed the maximum power dissipation of the copper trace. Detailed Description The FAN4010 measures the voltage drop (VSENSE) across an external sense resistor in the high-voltage side of the circuit. VSENSE is converted to a linear current via an internal operational amplifier and precision 100 Ω resistor. The value of this current is VSENSE/100 Ω (internal).
