  • Battery over voltage and over protection circuit and adjustable adapter current limit circuit
    Patent number: 6989981
    Abstract: A battery charging circuit is disclosed that includes protection circuitry and/or adapter current limit offset circuitry. The protection circuitry is operable to reduce or eliminate an overvoltage and overcurrent condition generated by a charge controller when a charging path is an open circuit, for example, when a battery is disconnected from the charging path. The adapter current limit offset circuitry is operable to generate an offset signal to an adapter current signal utilized by a charger controller.
