Portable Device Power Management

4 FAQs about [Portable Device Power Management]

Are portable devices getting more power hungry?

Devices are continuously getting more power hungry, outpacing battery development. Written by leading engineers in the field, This cutting-edge resource helps you overcome this challenge, offering you an insightful overview and in-depth guide to the many varied areas of battery power management for portable devices.

What makes a good battery management system?

The battery-management system must be intel-ligent to support different types of adapters and battery chemistries and must provide fast charging with high effi-ciency. At the same time, it is important to provide a good user experience with instant turn-on of the system, longer battery run time, and fast charging.

What is DPM & battery-supplement mode?

Combining the DPM control and the battery-supplement mode allows the adapter to be optimized to support the average power instead of the maximum peak system power, reducing the cost and achieving the smallest solution size. Portable systems such as tablets and smartphones require instant turn-on to provide a good user experience.

Why is thermal performance important for portable devices?

Thermal performance is critical for portable devices with a very thin profile because users can easily feel the heat dissipated from the printed circuit board. This heat is due to components that consume a lot of power, such as the bat-tery charger. To combat this, a high-efficiency charger and a good layout are very important.
