Abstract: Aspects of charger detection and optimization prior to host control are described herein. In various embodiments, a condition of whether reverse current is present on a system bus is detected. When the condition for reverse current is present, reverse current is sunk by one or more of various reverse current sink circuits. By relying upon one or more of the reverse current sink circuits, for safety, to address or mitigate the condition for reverse current, a detector may be able to identify or distinguish among several different types of charger or charging ports coupled to a system bus allowing a charger to be selected optimally. Further, an indicator of the type of charger or charging port coupled to the system bus is communicated over a single pin interface, for backwards compatibility with circuits capable of identifying between only two different types of chargers.

Abstract: Aspects of enhanced recovery mechanisms are described. A predetermined operating parameter for a power rail is set at the outset of system start. Afterwards, a processor is released to start with a power management circuit. In turn, the power management circuit receives a default operating parameter for the power rail from the processor, and stores the default operating parameter. The power management circuit also receives a runtime operating parameter for the power rail from the processor and modifies the operating parameter for the power rail according to the runtime operating parameter. If an error condition in the processor is encountered, the power management circuit may modify the operating parameter for the power rail according to the default operating parameter in response to a reset control signal from the processor. Use of the default operating parameter for the power rail may assist the processor to recover from the error condition.
