Figure 1: Some battery chemistries compared

An Integrated Solution to Li-ion Battery Management

John Carpenter, Product Development Manager, Qorvo

This article discusses the issue and describes cost-effective integrated solutions that can also add extra user benefits, including state-of-charge and state-of-health monitoring. Going back in history, perhaps hundreds of chemistries have been proposed for batteries. These have ranged from the original copper,

Digital POL Power

Dan Tooth PhD, Field Applications Engineer, Texas Instruments

An engineer designing with FPGAs or Processors often has to provide some serious amount of power at high efficiency over load. Not only must the rails be regulated correctly and not overheat, but additional functionality may be required. Recent evaluation boards from Xilinx (ML605 and SP605) for Virtex-6 and Spart
