A31315：3D霍尔效应传感器，用于旋转和线性位置测量

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.

根据ISO 26262开发，并且每个AEC-Q100级0级，该传感器适用于最苛刻的安全汽车系统，包括变速器和动力总成致动器，踏板位置，制动缸位置，换档和电子节流。在其他人失败的恶劣条件下，A31315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.
