Abstract

See full text

Systems and methods are provided for overcurrent protection in a battery charger. In certain embodiments, a method includes turning on an adapter switch to receive electrical power from an adapter connected to the battery charger; controlling a switching regulator to direct electrical current between the switching regulator and a battery port. Further, the method includes sensing a voltage drop that is related to the electrical current passing between the switching regulator and the battery port; comparing the sensed voltage drop against at least one reference voltage; and, when the sensed voltage exceeds the reference voltage, changing operation of the adapter switch to protect the battery charger from an overcurrent state.
