A31315：用于旋转和线性位置测量的三维霍尔效应传感器

The A31315 is a robust, fully integrated 3DMAG™ Hall-effect magnetic position sensor IC designed to support a wide range of non-contact rotary and linear position measurement in the automotive, industrial and consumer applications.

This family of sensors integrates vertical and planar Hall-effect elements to detect two out of three magnetic field components (X,Y and Z). Using configurable signal processing, linearization and angle calculation allows the A31315 to accurately resolve the absolute rotary (full 360° and short-stroke <360°) or linear position of a moving magnetic target.

The A31315 features ratiometric analog, PWM, or SENT (SAE J2716) interface options to output the angle between the two factory-selected axes or the field from a single axis. In addition, the SENT interface provides the option to output the field measurement from both channels.

该传感器根据ISO 26262标准开发，并通过AEC-Q100 0级认证，适用于要求最严格的安全汽车系统，包括变速箱和动力传动系执行器、踏板位置、制动缸位置、换挡器和电子油门。在其他飞机出现故障的恶劣条件下，A31315飞机茁壮成长。

The A31315 is available as a single die in the SOIC-8 package and stacked dual die in the TSSOP-14 package for applications that require full redundancy.
