3DMAG magnetic position sensor enables ADAS
Summary
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. Addressing the critical safety needs of autonomous driving systems and ADAS applications, the highly accurate A31315 position sensor contains advanced on-chip diagnostic features to ensure reliable, safe operation. It supports both rotary and linear position sensing in a robust design with excellent native angle error over temperature in any plane (<1.2° over the sensor’s full -40 ~ +150°C operating range). The highly versatile 3DMAG sensors, including the new A31315, address these constraints by easing system integration while enabling customers to achieve stringent accuracy requirements. The sensors’ wide range of programmable channel trim and linearisation options can easily be adjusted to the magnetic circuitry to optimise for both accuracy and manufacturing efficiency in end-of-line programming times for specific applications.
