Magnetic Position Sensor for Automotive and Industrial Applications

3DMAG sensors implement Allegro’s proven planar and vertical Hall-effect technologies to measure magnetic field components along three axes (X, Y, Z) allowing true 3D sensing capabilities with a wide magnetic dynamic range without saturation. The A31315 sensor address the critical safety needs of autonomous driving systems and advanced driver assistance systems (ADAS) applications including steering, braking, transmission and throttle systems. Superior accuracy and on-chip diagnostics help improve driver, passenger, and public safety for autonomous and driver-assisted vehicles while low power consumption and robust power management options help extend and optimize battery life.

The A31315 facilitate system integration while achieving strict accuracy requirement

They support flexible low-voltage programming through sensor outputs regardless of the interface (e.g., analogue, SAE J2716 SENT, PWM, I2C), allowing direct programming by a microcontroller in embedded designs and simplifying the interface for end-of-line system calibration.

Following Safety Element out of Context (SEooC) functional safety guidelines, the A31315 sensor supports ASIL-B (single die) and ASIL-D (dual die) system-level integration in accordance with ISO 26262 and is automotive qualified to AEC-Q100 Grade 0.
