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.
