ABSTRACT:
For a battery-operable device, an overload protector may prevent a catastrophic malfunction. Using the overload protector, a power source may enable controlled delivery of power to the battery-operable device as a result of a timely intervention. More particularly, in mobile devices or systems with variable power consumption components and/or operational modes, the frequency of the occurrence of tripping in a battery may be reduced or even eliminated in some cases. In one embodiment, a battery overload protector may continuously monitor available power from a power delivery unit and alert a processor-based system before a threshold of available power is reached by tracking power consumption against the threshold. The battery overload protector may issue a warning to the processor-based system in order to avoid exceeding the threshold. Responsive to the warning, one or more power conserving tasks may be initiated in the processor-based system, controllably consuming available power without reaching the threshold.
