DESCRIPTION

The A31315 3DMAG™ position sensor is designed for on-axis

and off-axis rotary as well as linear stroke position measurement

in automotive, industrial, and consumer applications.

This sensor integrates vertical and planar Hall-effect elements

with precision temperature-compensating circuitry 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.

On-chip EEPROM technology, capable of supporting up to

100 write cycles, is integrated for flexible programming of

configuration and calibration parameters and includes 92 bits

provided for customer device identification purposes.

The A31315 contains on-chip diagnostic features required for

high reliability automotive applications, including monitors of

both internal and external fault conditions.

Developed in accordance with ISO 26262 as a hardware safety

element out of context (SEooC) with ASIL B (single die) and

ASIL D (dual die) capability for use in automotive safety-related

systems when integrated and used in the manner prescribed in

the applicable safety manual and datasheet.

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
