Gasoline Multi-point fuel Injection (MPI) is the most widely used powertrain system for spark ignition engines. This system, where fuel is injected at low pressure in the inlet air manifold, is a proven, robust and simple technology. To control and optimize performance requires a wide range of semiconductor solutions that are specifically designed for automotive applications.
Our products and solutions
We have a wide and comprehensive offer including SPC5 32-bit microcontrollers and specifically designed system basis chips (SBC) that combine voltage regulators for the various DC rails, bus interface ICs for the most common standards including CAN, ISO 9141 K-line, variable reluctance sensors (VRS) and high- and low-side drivers.
