Abstract

Novel power-management chips (PMCS) and a related method to increase the flexibility of power-management chips and to disburden a main controller of mobile electronic devices, such as e.g. a mobile phone, have been achieved. Key of the invention is to implement a microprocessor system on a power-management chip. This microprocessor, having a flash-memory and a RAM has either no or minimum interaction with a main controller of the mobile electronic device since the microprocessor on the PMC is controlling all power supply requirements of the mobile electronic device. The novel PMC is more flexible; since it is free programmable and customers can adapt their PMC more efficiently to the specific purposes of their application.
