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.

Size Matters

Allegro’s compact current sensor solutions allow for reduction of size in inverters, reducing vehicle weight, number of components within the system (reducing BOM for the customer) and ensure high power density, increasing efficiency overall. 

We offer core-based and coreless Current Sensing IC solutions that are high-bandwidth efficient, user-programmable, and equipped with safety features such as self-checks and isolation capabilities that make them ideal for use in Inverters for electric vehicle applications.
