The objective of this SAE paper is to discuss a power stage partitioning which will provide a cost effective and flexible Infineon Technologies solution to control future E-Valve applications. To fulfil environmental demands, E-Valve applications will enable car manufacturers to: Dynamically reduce the number of working cylinders according to the drivers' torque requirements Have an efficient and variable control over the engine load in various conditions Dispense with throttles and exhaust recirculation valves The paper will describe: 1 The integration of the 4 MosFET and the future technology development required for the next system optimization. 2 Gate driver integration (3 different scenarios): Analog Interfacing between the μcontroller and the MosFETs with an integrated protection functionality (Scenario A).
