Abstract
A method of fault detection for battery chargers includes sensing a charge current applied to a battery with a resistive element. The method includes measuring a voltage across the resistive element. The method includes generating a trigger signal when the measured voltage across the resistive element exceeds a predetermined value. The method includes generating from the trigger signal an interrupt signal for a microprocessor. The method includes initiating an over-current handling routine in the microprocessor.
