ABSTRACT:
Embodiments of the present invention include systems and methods of controlling power in battery operated systems. In one embodiment, the present invention includes a switching regulator for boosting voltage on a depleted battery to power up a system. The system may communicate with an external system to increase the current received from the external system. Embodiments of the present invention include circuits for controlling power received from external power sources such as a USB power source. In another embodiment, input-output control techniques are disclosed for controlling the delivery of power to a system or charging a system battery, or both, from an external power source.
