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,

Selecting the Right MOSFET for Power Factor Correction Applications

Philip Zuk, Vishay

Power factor is the ratio of the real power (P = Watts) to the apparent power (VA = Volt Ampere); the goal is to achieve a power factor as close to 1 as possible. A load with a lower power factor
