current-sense resistor may degrade accuracy due to
the input offset of the current-sense amplifier.
The charging-current error amplifier (GMI) is compen-
sated at CCI. A 47nF capacitor at CCI provides suit-
able performance for most applications.
Maxim Integrated
Input Current Regulator
The total input current (from a wall cube or other DC
source) is the sum of system supply current plus the
battery-charging current. The input current regulator
limits the source current by reducing charging current
when input current exceeds the set input current limit.
System current normally fluctuates as portions of the
system are powered up or put to sleep. Without input
