Summary:A method and apparatus for a battery protection circuit. One embodiment provides a method for protecting a battery including receiving, with a comparator, a first voltage, the first voltage including a switch voltage across a current limiting switch provided on a current path of a battery and coupled to a current limiting control circuit to limit current output by the battery. The method also includes receiving, with the comparator, a reference voltage and comparing, with the comparator, the first voltage and the reference voltage. The method further includes controlling, with the comparator, a control switch to open when the first voltage exceeds the reference voltage.
