    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 dynamic power profiling are described herein. In various embodiments, a current sense operating mode is set for a current sense circuit, and the current sense circuit is enabled for operation. The current sense circuit senses an amount of current supplied by at least one of a plurality of power rails based on the current sense operating mode. The current sense circuit also accumulates and stores a value of the amount of current over a period of time. In certain aspects, a system controller averages the value of the amount of current based on the period of time. The current sense circuit may be configured to operate in various modes of operation including single or scan rail modes of operation, and the average of the value of the amount of current may be evaluated based on the modes of operation of the current sense circuit and/or the system.
