Product details
Overview
MLX90316LGO-BDG-100-RE from Melexis is an absolute rotary position sensor IC based on Triaxis® Hall technology, delivering 12-bit angular resolution and ±1° thermal accuracy over -40°C to +150°C. It supports programmable 0–360° angular range, ratiometric analog, PWM, or SPI serial output, and operates with 5 V supply in TSSOP-16 dual-die package for functional safety-critical automotive applications including throttle and steering wheel position sensing.
For engineers reviewing the MLX90316LGO-BDG-100-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its dual-die redundancy, SPI interface capability (BDG-100 variant), 14-bit serial output resolution, programmable transfer characteristic, and AEC-Q100 Grade 0 qualification for high-reliability motor-shaft and pedal position sensing.
Technical Context
The MLX90316LGO-BDG-100-RE integrates two independent silicon dies in a single TSSOP-16 package, each with Triaxis® sensing elements, IMC-based magnetic field detection, and dedicated DSP processing. Its architecture enables full hardware redundancy: separate VDD/VSS/VDIG rails, independent SPI interfaces (MOSI1/MISO1/SCLK1 and MOSI2/MISO2/SCLK2), and dual output stages (OUT1/OUT2) with configurable clamping and deadzone.
It implements end-of-line programmability via PTC-04 through standard pins (VDD-VSS-OUT), supporting calibration of offset, gain, linearity, thermal drift compensation, and filter coefficients. The device uses CoRDiC-based angular calculation from raw VX/VY sine/cosine signals, achieving 0.022°/LSB resolution in SPI mode with 14-bit output mapping across 360°.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90363GO-ADB-000-RE | Single-die TSSOP-16 with same Triaxis® core but no dual-SPI interface; 12-bit SPI only | Lacks hardware redundancy; suitable for ASIL-B systems where cost outweighs fail-operational need | Select when full ASIL-D redundancy is not required and BOM cost reduction is prioritized |
| AS5055A-DSOT | 14-bit SPI-only magnetic encoder; no analog/PWM outputs; requires external magnet calibration | No end-of-line programmability; limited thermal accuracy (±2.5°) and narrower temp range (-40°C to +125°C) | Select for non-automotive industrial use where SPI interface suffices and calibration infrastructure exists |
Compared with MLX90316LGO-BDG-100-RE, MLX90363GO-ADB-000-RE reduces redundancy overhead but sacrifices fault tolerance, while AS5055A-DSOT offers comparable resolution without programmable transfer characteristics or dual-die safety architecture.

FAQ
What output modes does the MLX90316LGO-BDG-100-RE support?
The MLX90316LGO-BDG-100-RE supports three configurable output modes: ratiometric analog voltage, PWM signal, and 3-wire SPI serial protocol. As a BDG-100 variant, it is factory-configured for SPI operation with dual independent interfaces (Die 1 and Die 2), enabling redundant communication paths. Analog and PWM modes remain accessible via programming but are secondary to the primary SPI functionality in this version.
How does the dual-die architecture of MLX90316LGO-BDG-100-RE improve functional safety?
The MLX90316LGO-BDG-100-RE integrates two fully independent sensor dies in one TSSOP-16 package, each with separate power (VDD1/VDD2), ground (VSS1/VSS2), digital supply (VDIG1/VDIG2), and SPI interfaces. This physical and electrical isolation enables cross-die comparison, fault detection, and fail-operational behavior-meeting ASIL-D requirements for automotive safety-critical applications such as steering and throttle control.
What is the angular resolution and accuracy of MLX90316LGO-BDG-100-RE in SPI mode?
In SPI mode, the MLX90316LGO-BDG-100-RE delivers 14-bit angular resolution mapped across 360°, resulting in 0.022°/LSB theoretical precision. Its thermal angular accuracy is specified at ±1° over the full -40°C to +150°C operating range, achieved through on-chip DSP compensation and programmable thermal drift parameters calibrated during end-of-line programming.
Can MLX90316LGO-BDG-100-RE be programmed after soldering to the PCB?
Yes, the MLX90316LGO-BDG-100-RE supports end-of-line programming via its standard connector terminals (VDD, VSS, and OUT pins) using the Melexis PTC-04 programmer. This allows full calibration of transfer characteristics-including offset, gain, linearity, clamping levels, and filter coefficients-without requiring additional programming headers or dedicated debug interfaces.
What magnetic configuration is required for optimal performance of MLX90316LGO-BDG-100-RE?
The MLX90316LGO-BDG-100-RE requires a diametrically magnetized dipole magnet positioned above the IC surface (end-of-shaft configuration). Optimal performance is achieved with magnetic flux density between 20–70 mT at the sensor location; exceeding 70 mT causes IMC saturation and increased linearity error. Airgap tolerance is up to ±0.5 mm, and lateral misalignment up to ±0.3 mm is supported due to the integrated magneto-concentrator.
