Allegro MicroSystems is pleased to announce the launch of its new AxMR™ technology platform, which the company expects to strengthen its position as the market leader in magnetic sensor integrated circuits (ICs).
The launch is the culmination of more than five years of extensive research and development efforts, a sizable investment that supports Allegro’s mission to create a broad portfolio of innovative magnetic sensor ICs for high growth applications within the automotive and industrial markets. The commitment to develop this platform has been augmented with a substantial investment in high precision thin film deposition tools and equipment within an advanced BCD wafer manufacturing facility, where high-volume manufacturing is under way.
Allegro’s AxMR™ technology platform integrates high sensitivity MR (magnetoresistive) sensor elements and high precision BiCMOS circuits on a single silicon integrated circuit. Through integration Allegro is able to combine our automotive grade, high voltage wafer processes with high accuracy, automotive grade MR sensors. The result is a family of high reliability, innovative, small form factor, monolithic ICs that easily fit into industry standard IC packages.
Allegro’s AGMR™ technology was designed to withstand the rigorous automotive under hood environment. AGMR™ technology is thermally stable to greater than 150°C, even in the presence of large magnetic fields. This platform sets the stage for Allegro to expand its product offerings in speed, electrical current, and angle sensing applications.
Allegro’s first generation AxMR™ ring-magnet Speed Sensor ICs are already in production at a leading Tier 1 automotive supplier of wheel speed sensors. These ICs rely on Allegro’s patented signal processing algorithms to meet the needs of both standard and direction detection wheel speed sensor platforms. GMR technology enables low jitter rotational speed measurements that are not possible with Hall effect ICs.
Allegro is actively developing monolithic back-biased GMR sensors for advanced engine management and transmission gear speed sensing applications, where the same low jitter measurements and large air gap performance are essential for advanced powertrain system operation.
Allegro also recently released its first GMR based current sensor IC, a device capable of resolving currents of less than 1 mA, and has plans to leverage MR technology to further disrupt the market for monolithic current sensor ICs.
