EMC Robust Design for Smart Power High Side Switches

The continued increase of electric and electronic systems in modern cars leads to growing electromagnetic noise which increases the risk of interference to the functional integrity of the system. This places greater demands to predict integrated circuit (IC) electromagnetic immunity in the early design phase. This paper describes an approach to early define the immunity of smart power automotive high side switches by using Direct Power Injection (DPI) simulations. A methodology will be presented to transform IC robustness requirements from a DPI level into a supply noise level, as a result of pin to pin impedance design.
