    Abstract: The disclosed systems and methods for current management can be used with system-on-a-chip (SoC) integrated circuits in, for example, battery-powered portable devices. The current management provides detection of supply current levels from a power management integrated circuit (PMIC) to an SoC. The PMIC signals, for example, using interrupts, the SoC when the supply current levels exceed thresholds. The SoC can then alter its operations to avoid exceeding the current capability of the PMIC. The current management can avoid the SoC experiencing a functional failure due to loss of power during high current conditions. Additionally, development methods can be used to optimize a system for various conditions besides the traditional worst-case design commonly used.

    Abstract: A system, a method and an apparatus are described. The apparatus includes a modem that responds to a thermal mitigation request by invoking different levels of thermal mitigation for different concurrently active connections. In some instances, the modem may invoke thermal mitigation with respect to a first active connection and refrain from invoking thermal mitigation with respect to a second active connection maintained by the modem. The apparatus determines the first and second active connections based on subscriptions corresponding to subscriber identification modules, an identification of a power amplifier or group of power amplifiers responsible for a thermal issue in the modem. The selection of mitigation levels for each active connection and decisions to invoke mitigation on one connection while refraining from invoking mitigation on another connection may be based on priorities of the active connections, including quality of service related priorities.
