Overview:
Battery pack and charger electronics have become critical components in portable devices. When considering the design of a power system for a portable electronic device, system designers are often challenged by efficiency, electrostatic discharge (ESD) and electromagnetic interference (EMI). With wireless devices, EMI has become a complication for portable battery packs, and embedded charging systems can compound the EMI issue. ESD can present a difficulty during the insertion of the pack. While these are three very common problems, they are often considered late in the design process and solutions are not well documented.
This live webcast reviews common electrical design challenges with portable devices. Learn a general model for battery pack cells, electronics, electrical connectors and charging circuitry. Principles for minimizing EMI will be presented by our experts. The flow of the current during an ESD hit and an attack by heavy RF field intensity will be discussed. Then, several design practices are presented to bypass ESD hits and RF fields away from critical circuits.
