... Input current is sensed with an external sense resistor low-inductance, precision resistor should be used for accurate input current limit. The ISL9220, ISL9220A limits the battery charge current when the input current limit threshold is exceeded. This allows the most efficient use of AC-adapter power without overloading the adapter output. ...
