Allegro MicroSystems launched a new AxMR technology platform, which integrates high-sensitivity MR (magnetoresistive) sensor elements and high-precision BiCMOS circuits on a single silicon integrated circuit (IC). Through integration Allegro has combined its 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 packages.
Allegro’s AGMR withstands harsh conditions, typically found in the automotive sector. AGMR is thermally stable to over 150°C, even in the presence of large magnetic fields.
Allegro’s first generation AxMR ring-magnet Speed Sensor ICs are already in production at a Tier 1 automotive supplier of wheel speed sensors. The ICs rely on Allegro’s patented signal processing algorithms to meet the needs of both standard and direction detection wheel speed sensor platforms.
