Abstract
A method and integrated circuit for preserving a battery'"'"'s charge and protecting electrical devices is disclosed. A maximum and a minimum battery voltage value at the output port are stored in a memory. A steady state battery voltage at the output port is measured and stored in the memory. A processor compares the measured steady battery voltage value to the maximum and the minimum battery voltage values. If the measured steady state battery voltage value is greater than the maximum battery voltage value, an over voltage state is reported by the processor. If the measured steady state battery voltage value is less than the minimum battery voltage value, a low battery voltage state is reported by the processor.
