Product details
Overview
MLX90316LDC-BDG-102-TU from Melexis is an absolute rotary position sensor IC based on Triaxis® Hall technology, delivering 12-bit angular resolution and ±10-bit thermal accuracy over -40°C to +150°C. It supports programmable analog (ratiometric), PWM, or SPI serial output modes and features a 360° angular range with end-of-line calibration of linearity, offset, gain, and clamping. Used in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90316LDC-BDG-102-TU datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOIC-8), confirmed SPI75AGC configuration, calibrated transfer function parameters, magnetic field tolerance (±700 mT), and dual-die redundancy readiness - all critical for functional safety-critical motor-shaft and pedal position designs.
Technical Context
The MLX90316LDC-BDG-102-TU implements a monolithic Triaxis® architecture with integrated magneto-concentrator (IMC) to detect horizontal magnetic flux components from an end-of-shaft dipole magnet. Its on-chip 16-bit RISC DSP performs real-time arctangent computation and digital signal conditioning using CoRDiC algorithms.
This variant is configured as SPI75AGC (Option Code BDG-102), enabling automatic rough gain adjustment at startup (FORCECRA75 = 1) and enhanced AGC convergence for varying airgap and magnet strength. It operates in Fast Mode (20 MHz clock, 200 μs sampling) with programmable FIR/IIR filtering and full diagnostic coverage including broken VDD/VSS detection.
Key Specifications

| 5 | OUT | Primary output: analog (ratiometric), PWM, or MOSI/MISO depending on mode |
| 6 | Test 1 | Factory test pin; must be grounded per EMC recommendation |
| 7 | VDIG | Digital I/O supply (tied internally to VDD); decoupling required for SPI noise immunity |
| 8 | VSS | Analog/digital ground reference; mandatory low-impedance connection to PCB ground plane |

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 |
|---|---|---|---|
| MLX90363KGO-ABD-000-TU | Dual-die TSSOP-16 package with full hardware redundancy; SPI-only interface; no analog/PWM outputs | Targeted at ASIL-D systems requiring fault-tolerant dual-channel architecture | Select when functional safety certification (ISO 26262) mandates hardware redundancy and deterministic SPI communication |
| AS5055A-DSOM | 14-bit resolution, 3.3 V only, no integrated IMC; requires external magnet alignment optimization | Lower-cost industrial positioning where ambient temperature stays below 125°C | Select for cost-sensitive non-automotive applications with controlled magnetic environment and no need for AEC-Q100 compliance |
Compared with MLX90316LDC-BDG-102-TU, the MLX90363 offers hardware-level fault containment but sacrifices analog/PWM flexibility and increases PCB area; the AS5055A delivers higher raw resolution but lacks on-chip IMC robustness and automotive qualification, limiting deployment in harsh environments.

FAQ
What output modes does the MLX90316LDC-BDG-102-TU support?
The MLX90316LDC-BDG-102-TU supports three configurable output modes: ratiometric analog voltage (0–100% VDD), 12-bit PWM (100–1000 Hz), and 14-bit SPI serial (3-wire, MOSI/MISO/SCLK). Its BDG-102 option code confirms SPI75AGC configuration, enabling automatic gain adjustment during startup for improved magnetic field tolerance.
How is the MLX90316LDC-BDG-102-TU calibrated for angular linearity?
The MLX90316LDC-BDG-102-TU uses end-of-line calibration via the Melexis PTC-04 programming unit, communicating exclusively through VDD-VSS-OUT pins. Calibration adjusts LNR_A/B/C coordinates, clamping levels, discontinuity point, and filter coefficients to correct for mechanical tolerances and achieve <1° total linearity error in final assembly.
Does the MLX90316LDC-BDG-102-TU meet automotive qualification standards?
Yes, the MLX90316LDC-BDG-102-TU is qualified to AEC-Q100 Grade 0 (-40°C to +150°C) and designed for ASIL-B automotive systems. Its diagnostics-including broken VDD/VSS detection, watchdog timer, and programmable clamping-support functional safety requirements in steering, throttle, and pedal applications.
What is the role of the Integrated Magneto-Concentrator (IMC) in the MLX90316LDC-BDG-102-TU?
The IMC in the MLX90316LDC-BDG-102-TU concentrates horizontal magnetic flux components from an end-of-shaft dipole magnet onto the on-die Triaxis® Hall elements. This enables accurate 360° absolute angle measurement with high immunity to airgap variation (±0.5 mm) and off-axis misalignment, reducing mechanical design constraints.
Can the MLX90316LDC-BDG-102-TU be used in dual-die redundant configurations?
No-the MLX90316LDC-BDG-102-TU is a single-die SOIC-8 device. However, its pinout and firmware are compatible with the dual-die MLX90316KGO-ABD-000-TU (TSSOP-16), allowing migration to hardware-redundant architecture without redesigning the core signal chain or calibration process.
