Allegro MicroSystems Announces Groundbreaking New Position Sensors for ADAS Applications

Allegro MicroSystems announced the launch of its A33110 and A33115 magnetic position sensors. Designed for advanced driver assistance systems (ADAS) applications that require high levels of accuracy and heterogeneous signal redundancy, Allegro’s newest sensors combine the company’s vertical Hall technology (VHT) with cutting-edge tunneling magnetoresistance (TMR) technology in a single sensor package. These groundbreaking angle sensors are the first of their kind to feature this technology combination in a single package. This VHT + TMR offering is a superior heterogeneous redundant sensor solution and is an essential step toward enabling the reliability required for advanced levels of automation in vehicles.

The safe operation of a vehicle requires the highest level of diagnostic coverage in its safety-critical systems. Allegro’s VHT featured in the new A33110 and A33115 enables accurate safety checks, including low-field and missing-magnet detection. These high-resolution sensors are ASIL D-compliant, with heterogeneous redundancy reducing the likelihood of dependent failures by leveraging the best of both TMR technology and VHT (more info).
