1. A battery charger integrated circuit comprising:

  • a temperature sensor circuit, electrically coupled to receive a first reference signal and a temperature signal, operable to generate a second reference signal, wherein when the temperature signal is greater than the first reference signal, an adjust signal is generated to adjust the second reference signal; and

    a charging current generator circuit, electrically coupled to receive the second reference signal, operable to generate a charging current based on the second reference signal, wherein the charging current is reduced when the temperature signal is greater than the first reference signal such that a charging die is prevented from exceeding a predetermined temperature.
