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.
