APPLICATION NOTE 4268

Ultra-Small UCSP™ Devices Improve Battery Management in Portable Applications

By: Maurizio Gavardoni

Abstract: This application note focuses on battery management in smartphones, cellular phones, and other portable devices. It describes how to solve the problems of estimating remaining battery life and implementing protection from battery overcurrent conditions with very simple, ultra-small and ultra-low-power devices such as a current-sense amplifier and a comparator.
