Electric Power Steering

Replacing traditional hydraulic power steering systems to improve vehicle fuel efficiency and enable foundational ADAS features requires a robust, reliable, and highly efficient electronic system.

As a market leader shipping over 100 million ICs into EPS systems annually, Allegro provides a comprehensive ASIL-compliant portfolio including high-resolution torque and angle sensors, robust motor drivers, and safety PMICs, all developed through our certified ISO 26262 process.

This is Innovation with Purpose: enabling a direct improvement in fuel economy of up to 12 gallons per year while providing the precise control necessary for safety-critical ADAS features like lane-keeping assist and automated parking assist.
