Battery Power Management for Portable Electronic Devices

With the trend toward smaller and lighter mobile wireless devices, using larger batteries is not an option. Designers must optimize the battery operating time of their devices, and analyzing battery current drain can help them accomplish that task. Battery drain analysis entails testing and characterizing the device, its subcircuits, and the battery, both independently and in combination. It includes characterizing current drain out of the battery using different device operating modes and parameters to provide insight into how device operation affects battery drain. This enables designers to analyze design tradeoffs that impact current drain, so they can design the device to maximize battery life. Read full description of Keysight's battery drain solution and its new automation capabilities.
