Product details
Overview
MLX90316LDC-BCG-000-SP 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 ratiometric analog, PWM, or SPI serial output modes and features programmable transfer characteristics for end-of-line calibration in automotive throttle, steering, and pedal position sensing.
For engineers reviewing the MLX90316LDC-BCG-000-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its SOIC-8 package, dual-die redundancy option, 360° programmable angular range, integrated magneto-concentrator (IMC), and diagnostic capabilities including broken-track detection.
Technical Context
The MLX90316LDC-BCG-000-SP implements a monolithic Triaxis® architecture with on-chip DSP processing of VX/VY magnetic field components to compute absolute angular position. Its IMC enables robust operation across mechanical airgap and off-axis tolerances without external flux concentrators.
It integrates a 16-bit RISC microcontroller (5 MIPS @ 20 MHz), 10 KB ROM, 256 B RAM, and 128 B EEPROM for user-programmable parameters including output mode, clamping levels, linearity correction, and filter coefficients. Output configuration includes analog (ratiometric), 12-bit PWM (100–1000 Hz), or 14-bit SPI serial protocol.
Key Specifications

| Multi-Mode Output Flexibility | Single device supports analog (ratiometric), PWM (100–1000 Hz), or SPI (14-bit, 3-wire) outputs-selected via EEPROM configuration, not hardware change |
| Automotive-Grade Diagnostics | Real-time broken-track (VDD/VSS), watchdog timeout, and configurable diagnostic bands ensure ASIL-B–compatible functional safety support |
| Thermal Stability Optimization | Two-stage thermal drift compensation: front-end offset/sensitivity drift correction (±90 LSB15) and DAC/output-stage drift correction (±0.4% VDD) |
Applications
| Steering Wheel Position Sensing | Pedal Position Sensing |
|---|---|
Use Scenario: Real-time measurement of steering column rotation angle for EPS control and ADAS lane-keeping feedback. IC Role / Device Role / Timing Role: Absolute angular position sensor interfacing directly to MCU ADC or PWM capture peripheral; no external signal conditioning required. Use Value: 12-bit resolution and ±1.5° full-range accuracy enable precise torque assist mapping; IMC-based robustness eliminates need for tight airgap control during assembly. |
Use Scenario: Detection of accelerator or brake pedal angular displacement in ICE and EV powertrain systems. IC Role / Device Role / Timing Role: Primary position transducer feeding engine control unit (ECU) with ratiometric analog or PWM signal synchronized to vehicle CAN timing. Use Value: Programmable clamping and deadzone allow OEM-specific pedal travel limits and idle detection; L-grade temp rating ensures reliability near hot exhaust components. |

Use Scenario: Closed-loop monitoring of throttle butterfly valve angle in gasoline direct injection engines. IC Role / Device Role / Timing Role: Redundant-capable position feedback element supporting dual-signal architectures for fail-operational control. Use Value: Dual-die TSSOP-16 variant available; this SOIC-8 version provides single-channel high-accuracy output with built-in diagnostics for fault detection and reporting. |
Use Scenario: Continuous measurement of suspension compression/expansion for adaptive damping and ride height leveling systems. IC Role / Device Role / Timing Role: Contactless angular transducer mounted on torsion bar or linkage, reporting position via SPI to body control module. Use Value: 360° programmable range accommodates multi-turn mechanical linkages; 14-bit SPI output delivers sub-0.025° resolution for fine-grained height control. |
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 package with full redundancy; higher current draw (2× IDD); SPI-only output mode | Required for ASIL-D–targeted systems needing hardware redundancy; not pin-compatible with SOIC-8 | Select when functional safety mandates dual independent sensing paths and layout space permits TSSOP-16 |
| AMS3045-2000 | SOIC-8, 12-bit analog/PWM only; no SPI; lower temp grade (–40°C to +125°C); no programmable linearity | Suitable for cost-sensitive non-safety-critical applications where fixed transfer curve suffices | Choose for simplified calibration workflows and reduced BOM count where 150°C operation and field-programmability are unnecessary |
Compared with MLX90316LDC-BCG-000-SP, the MLX90363 offers hardware redundancy at the expense of pin compatibility and flexibility, while the AMS3045-2000 trades programmability and extended temperature range for lower system integration complexity and cost.

FAQ
What output modes does the MLX90316LDC-BCG-000-SP support?
The MLX90316LDC-BCG-000-SP supports three configurable output modes stored in EEPROM: ratiometric analog (0–100% VDD), PWM (100–1000 Hz, programmable frequency and polarity), and 3-wire SPI serial protocol delivering 14-bit angular data. Mode selection requires programming via PTC-04; no hardware changes are needed after initial configuration.
How is the MLX90316LDC-BCG-000-SP calibrated for specific mechanical setups?
MLX90316LDC-BCG-000-SP supports end-of-line calibration using Melexis' PTC-04 programmer via the VDD–VSS–OUT pins only. Users can program offset, gain, clamping levels, deadzone, multi-point linearity correction, and thermal drift compensation-enabling precise matching to magnet geometry, airgap, and mechanical linkage without modifying firmware or hardware.
Does the MLX90316LDC-BCG-000-SP include built-in diagnostics?
Yes, MLX90316LDC-BCG-000-SP integrates multiple diagnostics: broken-VDD/VSS detection, watchdog timeout (5 ms), configurable diagnostic bands, and programmable clamping/deadzone. These features support ASIL-B compliance and enable fail-safe reporting in automotive ECU designs without external monitoring circuitry.
What is the role of the Integrated Magneto-Concentrator (IMC) in the MLX90316LDC-BCG-000-SP?
The IMC in MLX90316LDC-BCG-000-SP concentrates and directs magnetic flux onto the on-die Triaxis® Hall elements, enabling accurate measurement of the horizontal VX/VY field components. This allows robust 360° absolute angle sensing with relaxed mechanical tolerances-airgap variations up to ±0.5 mm and lateral misalignment up to ±0.3 mm have minimal impact on accuracy.
Can the MLX90316LDC-BCG-000-SP operate in harsh automotive environments?
Yes, MLX90316LDC-BCG-000-SP is qualified for –40°C to +150°C operation (L-grade), features reverse-voltage protection (–10 V), overvoltage tolerance (+20 V), and meets automotive EMC requirements. Its SOIC-8 package is RoHS-compliant and validated for reflow soldering per J-STD-020, making it suitable for under-hood engine control and chassis applications.
