Description

The FAN4010 is a high-side current sense amplifier

designed for battery-pow ered systems. Using the

FAN4010 for high-side pow er-line monitoring does not

interfere w ith the battery charger’s ground path. The

FAN4010 is designed for portable PCs, cellular phones,

and other portable systems w here battery / DC pow er-

line monitoring is critical.

To provide a high level of flexibility, the FAN4010

functions w ith 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 w ith a single resistor, accommodating a w ide

range of battery voltages and currents. The FAN4010

features allow it to be used for gas gauging as w ell as

uni-directional or bi-directional current monitoring.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Symbol Parameter Min.

Detailed Description The FAN4010 measures the voltage drop (V SENSE) across an external sense resistor in the high-voltage side of the circuit. V SENSE is converted to a linear current via an internal operational amplifier and precision 100 Ω resistor. The value of this current is V SENSE/100 Ω (internal). Output current flow s from the IOUT pin to an external resistor ROUT to generate an output voltage proportional to the current flow ing to the load.
