Product details
Overview
MLX90316LDC-BDG-100-RE from Melexis is an absolute rotary position sensor IC using Triaxis® Hall technology to detect angular position of an end-of-shaft dipole magnet with 12-bit resolution, programmable 0–360° range, and selectable ratiometric analog, PWM, or SPI output modes. It operates from -40°C to +150°C in SOIC-8 package and is used in automotive throttle, steering wheel, and pedal position sensing.
For engineers reviewing the MLX90316LDC-BDG-100-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its dual-die redundancy option (TSSOP-16), on-chip DSP-based angular calculation, IMC-enhanced mechanical tolerance immunity, and end-of-line programmability via PTC-04 through VDD/VSS/OUT pins.
Technical Context
The MLX90316LDC-BDG-100-RE integrates a Triaxis® magnetic front-end with on-chip IMC to sense horizontal flux components, enabling robust contactless angular measurement over ±700 mT magnetic field and wide airgap tolerances. Its 16-bit RISC DSP performs real-time arctangent computation and supports full transfer characteristic programming including offset, gain, clamping, linearity, and thermal drift compensation.
This variant features SPI serial protocol output (BDG-100 suffix), 14-bit angular data resolution mapped to 360°, and dual-die architecture for functional safety compliance. It includes EEPROM-stored calibration parameters, 40-bit unique ID, and programmable diagnostics such as broken VDD/VSS detection and watchdog timeout (5 ms).

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-SP | TSSOP-16 dual-die, 16-bit SPI output, higher resolution (0.0055°/LSB), extended diagnostics | Targeted at ASIL-D systems requiring dual-channel redundancy and enhanced fault coverage | Select when full ISO 26262 ASIL-D compliance and dual-die fault containment are required |
| AS5055A-DSOM | 14-bit SPI-only output, no analog/PWM, smaller QFN-16 package, lower max temp (-40°C to +125°C) | Optimized for space-constrained industrial encoders and non-automotive motion control | Select when board space is limited and automotive-grade temperature range is not required |
Compared with MLX90316LDC-BDG-100-RE, the MLX90363 offers higher resolution and full ASIL-D support but requires TSSOP-16 layout; the AS5055A reduces footprint and cost but sacrifices temperature range and output flexibility.

FAQ
What output interfaces does the MLX90316LDC-BDG-100-RE support?
The MLX90316LDC-BDG-100-RE supports three configurable output modes: ratiometric analog voltage (0–VDD), PWM (100–1000 Hz), and 3-wire SPI (MOSI/MISO/SCLK). The BDG-100 suffix confirms SPI capability. All modes are selected and calibrated via the PTC-04 programmer using only VDD, VSS, and OUT pins - no additional hardware interface is needed. The MLX90316LDC-BDG-100-RE delivers 14-bit angular data over SPI and 12-bit resolution in analog/PWM modes.
How is the MLX90316LDC-BDG-100-RE calibrated for specific mechanical setups?
Calibration is performed end-of-line using Melexis' PTC-04 programming unit, which communicates exclusively through the MLX90316LDC-BDG-100-RE's VDD, VSS, and OUT pins. Users program angular range (0–360°), transfer characteristics (offset, gain, clamping, linearity), filter settings, and diagnostic thresholds into on-chip EEPROM. The MLX90316LDC-BDG-100-RE retains all calibration data after power cycle and supports lock/unlock commands to prevent unauthorized reprogramming.
Does the MLX90316LDC-BDG-100-RE meet automotive reliability standards?
Yes, the MLX90316LDC-BDG-100-RE is qualified to AEC-Q100 Grade 0 (−40°C to +150°C) and designed for under-hood automotive use. It includes built-in diagnostics such as broken VDD/VSS detection, watchdog timer (5 ms timeout), EEPROM CRC, and memory lock. Its Triaxis® IMC architecture provides exceptional immunity to mechanical tolerances (airgap, off-axis), making it suitable for steering, throttle, and pedal position sensing per ISO 26262 functional safety requirements.
What is the role of the Integrated Magneto-Concentrator (IMC) in the MLX90316LDC-BDG-100-RE?
The IMC is a ferromagnetic structure integrated directly onto the MLX90316LDC-BDG-100-RE die surface that concentrates and redirects horizontal magnetic flux components toward the Hall sensing elements. This enables accurate angular measurement using low-cost dipole magnets placed above the package, while rejecting interference from vertical fields and improving signal-to-noise ratio. The IMC eliminates need for external flux concentrators and allows robust operation across wide airgaps - a key advantage of the MLX90316LDC-BDG-100-RE in mechanically variable environments.
Can the MLX90316LDC-BDG-100-RE operate with supply voltages outside 4.5–5.5 V?
The MLX90316LDC-BDG-100-RE is specified for nominal 5 V operation (4.5–5.5 V), with absolute maximum ratings of −10 V reverse voltage and +20 V overvoltage on VDD. Operation outside the recommended range risks parametric degradation or permanent damage. Its internal 3.3 V regulator powers digital blocks, and output stages are ratiometric to VDD - so supply variation directly affects analog/PWM output scaling. For stable performance, maintain VDD within specification; the MLX90316LDC-BDG-100-RE includes POR circuitry that holds reset until VDD exceeds 2.7 V.
