Abstract
A method and apparatus for a battery protection circuit. One embodiment provides a method for protecting a battery including detecting, with a voltage divider having a first resistor and a second resistor connected in series, a voltage across a first current limiting switch and a second current limiting switch provided on a current path of a battery. The method also includes providing, with a control output provided between the first resistor and the second resistor of the voltage divider, a control signal to the first current limiting switch, wherein the control signal opens and closes the first current limiting switch. The method further includes controlling, with the voltage divider, the first current limiting switch to open when the voltage across the first current limiting switch and the second current limiting switch exceeds a predetermined threshold.
