Description

The FAN4010 is a high-side current sense ampliﬁ er

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 ﬂ exibility, 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.
