Allegro MicroSystems Inc. announces the release of the A31315 sensor, the newest member of the 3DMAG family of rotary and linear magnetic position sensor ICs for automotive and industrial applications.
3DMAG sensors combine Allegro’s proven planar and vertical Hall-effect technologies to measure magnetic field components along three axes (X, Y, Z), enabling true 3D sensing capabilities with a wide magnetic dynamic range without saturation.
Continued advancements in advanced driver assistance systems (ADAS) and autonomous driving systems present new performance and functional safety challenges for system integrators. The A31315 sensor addresses these challenges by delivering the measurement accuracy and performance necessary to meet the stringent requirements of safety-critical automotive applications including steering, braking, transmission and throttle systems.
The sensors’ flexible 3D Hall front end and configurable signal processing architecture enable highly accurate, absolute linear position and rotary position measurements up to 360° while easing system integration challenges by providing greater freedom in sensor placement. Existing Allegro 3DMAG devices, such as the ALS31300 and ALS31313 sensors, also support 3D magnetometer applications in which all three magnetic components (BX, BY, BZ) are required to track complex magnetic movements.
Key benefits include:
- Superior accuracy and on-chip diagnostics help improve driver, passenger, and public safety for autonomous and driver-assisted vehicles.
- High performance and flexibility across design placements and use cases simplifies Bills of Materials.
- Low power consumption and robust power management options help extend and optimize battery life.
