Hybrid and Electric Vehicle Systems

We believe the future is electric – and we know vehicle electrification requires innovative solutions. We’re ready for the rEVolution with smaller, lighter, and more efficient power and sensor semiconductors. You’ll be able to pack in the features your customers want while still meeting your miles per charge goals. 

Let’s design your EV systems together. Check out our broad family of automotive-grade devices for battery monitoring, on-board chargers, DC-DC converters, starter generators, and more. 

We offer benefits like superior safety for ADAS and autonomous vehicles, including ISO 26262 certification; high levels of integration for redundancy and heterogenous diversity; current sensors that maximize power density; and market-leading, low noise sensors and robust motor drivers that reduce undesired noise in electric motors.
