Product details
Overview
MLX90316LDC-BDG-100-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 360° angular range, ratiometric analog, PWM, or SPI serial output, and operates with a single SOIC-8 package for non-redundant automotive sensing applications such as throttle and pedal position detection.
For engineers reviewing the MLX90316LDC-BDG-100-TU datasheet, pinout, applications, or equivalent options, this page provides verified technical context, calibrated output behavior, magnetic field tolerance specs, functional safety diagnostics, and real-world deployment guidance for high-temperature automotive subsystems.
Technical Context
The MLX90316LDC-BDG-100-TU integrates a Triaxis® Hall sensor with on-die IMC (Integrated Magneto-Concentrator) to detect horizontal magnetic flux components from an end-of-shaft dipole magnet. Its DSP performs real-time rectangular-to-polar conversion using CoRDiC algorithms, enabling robust angular computation across mechanical airgap and off-axis tolerances.
This variant implements SPI serial protocol (indicated by BDG-100 option code), features dual 12-bit DAC/PWM output stages, and includes programmable diagnostics-such as broken VDD/VSS detection and watchdog timeout-configured via EEPROM and calibrated using the PTC-04 programming unit through VDD-VSS-OUT pins only.

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-100-SP | Dual-die TSSOP-16 package with full hardware redundancy; SPI-only output; higher current draw (2× IDD) | Required for ASIL-D systems needing physical redundancy; unsuitable for space-constrained SOIC-8 layouts | Select when functional safety mandates dual independent signal chains and layout allows TSSOP-16 footprint. |
| MLX90375ELD-100-SP | Next-generation Triaxis® IC with 16-bit resolution, integrated temperature sensor, and SENT output; same SOIC-8 package | Supports higher-precision applications (e.g., steer-by-wire) and direct connection to SENT-compatible ECUs | Choose for new designs requiring improved resolution, embedded temp compensation, or SENT protocol compatibility. |
Compared with MLX90316LDC-BDG-100-TU, MLX90363KGO-100-SP adds hardware redundancy at the cost of size and power, while MLX90375ELD-100-SP upgrades resolution and interface capability within the same SOIC-8 form factor-making it a drop-in performance upgrade where SENT infrastructure exists.

FAQ
What output protocols does the MLX90316LDC-BDG-100-TU support?
The MLX90316LDC-BDG-100-TU supports three output protocols: ratiometric analog voltage (0–100% VDD), PWM (100–1000 Hz, programmable frequency and polarity), and SPI serial interface (3-wire, 14-bit angle data). The BDG-100 option code confirms SPI capability is factory-enabled and calibrated.
How is the MLX90316LDC-BDG-100-TU calibrated for custom angular ranges?
The MLX90316LDC-BDG-100-TU is calibrated using Melexis' PTC-04 programming unit, which communicates exclusively through the VDD–VSS–OUT pins. Users program angular range, offset, gain, clamping, and filtering parameters into on-chip EEPROM during end-of-line testing-no additional interface hardware required.
Does the MLX90316LDC-BDG-100-TU meet AEC-Q100 reliability standards?
Yes, the MLX90316LDC-BDG-100-TU is qualified to AEC-Q100 Grade 0 (−40°C to +150°C), with full characterization of thermal drift, magnetic sensitivity, and diagnostic coverage across that range. Its L-temperature suffix and SOIC-8 construction reflect this automotive qualification.
What is the role of the Integrated Magneto-Concentrator (IMC) in the MLX90316LDC-BDG-100-TU?
The IMC on the MLX90316LDC-BDG-100-TU die concentrates horizontal magnetic flux components from an end-of-shaft dipole magnet, enabling precise angular measurement despite mechanical airgap variations (±0.5 mm) and off-axis misalignment-key to robustness in automotive mounting environments.
Can the MLX90316LDC-BDG-100-TU operate with supply voltages other than 5 V?
The MLX90316LDC-BDG-100-TU is specified for 4.5–5.5 V operation. While absolute maximum rating allows up to +20 V on VDD, sustained operation outside 4.5–5.5 V violates electrical specifications-including accuracy, thermal drift, and output stage behavior-and is not supported for production use.
