Apparatus and method to integrate a digital pulse width modulation controller, a digital battery charger controller, and other power management functions in a digital system integrated circuit to increase the design flexibility, manufacture simplicity, improve efficiency, and reduce the complexity and cost of the system design is disclosed. The digital controller and power management circuit can be designed and stored in program code to be implemented when the system is designed. The power management devices and the system can share resources including ADCs, memory, computing function and communication function.
