Power management technology
ST-Ericsson’s power management solutions use an array of sophisticated technologies to ensure that even the most advanced smartphones still can last a day on one battery charge. For example, ST-Ericsson has developed state-of-the-art power conversion and heat management techniques that prevent intensively-used devices from overheating.
Our power management solutions are based on leading-edge 130nm silicon technology, which enables devices to benefit from the optimal combination of low power, high performance and low bill-of-materials.
To address different segments of the mobile device market, ST-Ericsson has developed a range of power management solutions:
STANDALONE SOLUTIONS
Aimed at smartphones, tablets and other mid-to-high-end devices, ST-Ericsson’s standalone “analog and mixed-signal” systems manage power consumption and battery charging, while also supporting high-performance audio and video solutions.
ST Ericsson’s standalone analog and mixed signal solutions support:
- Very high power sources and efficient conversion (>90%) with the accurate performance needed to support the most demanding devices, such as tablet computers
- High voltage battery management section to guarantee safe and efficient battery charging
- High-speed interfaces, such as USB2 and Video interface
- Crystal-clear audio performances for headsets (>100db SNR) and loudspeakers (2W) with multi-channel playing and recording capabilities
- Micro-controller and its memories allowing smart and powerful control of each functions of the mixed signal device and increasing the configurability
INTEGRATED SOLUTIONS
At the mid-to-low end of the mobile phone market, manufacturers generally prefer analog and mixed-signal solutions to be integrated into the main system-on-a-chip device, enabling production of very compact, highly cost-effective devices. ST-Ericsson’s market-proven solutions are all integrated onto one piece of silicon, saving space and cost for device manufacturers.
