Design

It is a common misconception that designing an IC for system-level ESD requirements simply requires an increase in the capability of the ESD cells, which are already present for safe handling ESD requirements, like Human Body Model (HBM).

Most EMI issues are caused by a resonance that is excited somewhere in the system. It may be a resonance of a cable acting as an antenna or a heatsink energized by the power electronics switches bolted to it, becoming a good radiator. In this article, we look at the indicators that signal the presence of structural resonances and provide techniques for fixing the EMI issues. Practical case studies are presented to demonstrate the techniques.

When Gaston Planté invented the rechargeable battery in 1859, a new system of stored energy emerged. Today, digital technology has helped to make the electrochemical battery smart by providing a window into a battery’s state-of-function.

The growing application of lithium-ion batteries brings with it an increased risk of unanticipated energy releases and thermal runaway. Quantifying battery energy release characteristics during product design can help mitigate those risks.

The state of health of cells in a battery pack under operating condition is difficult to obtain through existing IEC and ISO standard methods under laboratory conditions. However, a cell state of health (SOH) profile shall be able to establish by the comparison of electro-impedance spectroscopy (EIS) generated statically versus dynamic operating data retrieved by battery management system (BMS) communication interface as fragments of EIS.
