Gasoline Direct Injection (GDI)  

Regulations limiting vehicle emissions, combined with the need to balance vehicle performance and fuel economy has pushed automakers to develop new and innovative engine architectures. Gasoline Direct Injection (GDI) engines can provide an optimum combination: fuel efficiency and high performance.

To control and optimize vehicle performance at the appropriate cost point requires a wide range of semiconductor solutions that are specifically designed to  ensure compliance with emissions regulations and provide greater fuel efficiency.

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.
