Electromechanical Braking

The future of braking is fully electric, removing hydraulics to save weight and complexity. This "brake-by-wire" architecture demands the highest level of functional safety (ASIL D) and fail-operational performance to replace the mechanical link.

Allegro provides a complete suite of components developed through our certified ISO 26262 process, including redundant position sensors, high-performance motor drivers, and safety PMIC with integrated wheel speed sensor interface, to control the electric motors on each brake caliper with the utmost precision and reliability.

To deliver the highest level of safety and quality for the future of braking, enabling faster response, improved efficiency through enhanced regenerative braking, and the foundational control needed for fully autonomous vehicles.
