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.
