Fairchild Semiconductor's EcoSPARK® 2 Ignition Coil Driver Reduces Power Dissipation, Enhances Performance of Ignition IGBTs

Fairchild FGD3040G2 FDG3440G2

Device Minimizes Heat Sink Requirements, Lowers Operating Temperatures

In order to meet demanding emissions and high fuel efficiency requirements in present and emerging ignition systems, automotive designers need higher performance ignition coil driver technology. To help designers meet these requirements, Fairchild Semiconductor has introduced the latest generation of ignition IGBTs that provide reduced power dissipation in a smaller footprint. The EcoSPARK® 2, FGD3040G2 and FDG3440G2 ignition coil drivers, deliver up to 20 percent reduction VSAT performance without a significant reduction of Self Clamping Inductive Switching (SCIS) energy. This optimized feature reduces power dissipation, lowers heat sink requirements and operating junction temperatures.
