Increasing fuel costs and emission regulations force the car manufacturers to develop powerful but efficient engines. The 3-liter car (3-liter/100 km fuel consumption → 80 miles/gallon) is one of the slogans. To fulfill these requirements a fully electronic controlled Engine Management is necessary. Carburetor systems are replaced by fuel injection systems. Direct injection for Diesel as well as for gasoline engines is the clear trend for the future. The mechanical throttle systems, used for a long time will not fit to the requirements of direct injection. A DC motor for electronic throttle control in conjunction with λ regulation and exhaust gas recirculation are the key elements for low emission cars. Also the automotive ignition system is in a process of change today.

Driven by factors like consumption, power output per liter, comfort and more stringent exhaust gas standards the powertain control area, has developed rapidly in the last decades. This trend has also brought with it many innovations in the ignition application. Today we can see a trend to Pencil-coil or Plug-top-coil ignition systems. The next step in system partitioning is to remove the power driver from the ECU and place it directly in/on the coil body. The advantages of the new partitioning - e.g. no high voltage wires, reduced power dissipation on the ECU - are paid with different, mainly tougher requirements for the electronic components. By using specialized technologies for the different functions - IGBT for switching the power, SPT for protection, supply and diagnostics - in chip-on-chip technology all required functions for a decentralized ignition system can be realized in a TO220/ TO263 package.

Fuel efficiency and clean combustion engine versus high engine performance - which will increase up to factor 10 in the next 5 years - with less engine displacement are driving more complex engine control systems in today's and future vehicles. The challenge is not only to design a perfect engine, but also to incorporate the right semiconductors. Beside this demand on high sophisticated electronics the demand on cost reduction - especially for small cars - is one driving factor for a smart partitioning. Infineon offers sensors, microcontrollers and power semiconductors for today's engine management platforms and therefore owns the right technologies to manufacture those devices. This opens up the possibility to integrate more functionality in less devices as in today's partitioning or to define electronics to simplify complex control strategies and to optimize the performance of each device.
