Abstract: A power management system that can include an application processor and a power management unit (PMU). The PMU can generate a regulated output voltage based on control signals generated by a switch control module of the application processor. The control signals can be determined based on a comparison of monitored voltages within the application processor and a generated reference voltage. The reference voltage can be generated based on fed back signals corresponding to the control signals. The application processor and the PMU can be formed utilizing different size manufacturing process technologies. For example, the PMU can be formed utilizing a larger size manufacturing process technology than the application processor.

Abstract: A power management unit accurately measures and controls charging current. The power management unit may be implemented more efficiently than prior designs, leading to cost savings in the implementation of the power management unit as well as in the implementation of the device that incorporates the power management unit. The power management unit incorporates a model of an external charge control device (e.g., a transistor) and uses that model in a way that allows the power management unit to eliminate external device pins and other circuitry.
