ABSTRACT:
Systems and methods for selectively changing the current threshold of current limiting circuitry are provided. The current limit threshold of current limiting circuitry may be selectively changed based on a detected power source using a resistive network. The current limiting threshold may be selected by changing a resistance value of a resistive network electrically coupled to an input on the current limiting circuitry (e.g., battery controller) for programming the current limiting threshold. The resistance value received by the currently limiting circuitry at this input may set the current threshold and thus the maximum magnitude of current that may be provided to charge a battery or other energy storage device located in the electronic device (e.g., a mobile phone).
