Product details
Overview
MLX90316EDC-BCG-000-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 +125°C. It senses the horizontal magnetic field component via an integrated magneto-concentrator (IMC), supports programmable 0–360° angular range and linear transfer characteristic, and outputs ratiometric analog, PWM, or 14-bit SPI data - used in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90316EDC-BCG-000-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its SOIC-8 package, dual-die redundancy option, end-of-line programmability via PTC-04, 12-bit analog/PWM resolution, and robustness against airgap and off-axis mechanical tolerances.
Technical Context
The MLX90316EDC-BCG-000-RE integrates a Triaxis® Hall front-end with IMC, 16-bit RISC DSP, 128 B EEPROM, and configurable output stages. Its digital signal processing computes absolute angle from sine/cosine raw signals with 15-bit ADC resolution in slow mode and supports programmable clamping, deadzone, linearity correction, and thermal drift compensation.
It operates in two speed modes (7 MHz / 20 MHz main clock), offers selectable filter configurations (FIR/IIR/hysteresis), and implements diagnostics including broken VDD/VSS detection, watchdog timeout (5 ms), and self-test via dedicated diagnostic output pins - all calibrated and configured via 3-wire serial interface using VDD/VSS/OUT terminals.

Pinout & Package
MLX90316EDC-BCG-000-RE is housed in an RoHS-compliant SOIC-8 package with 1.27 mm pitch, 5.0 mm × 6.2 mm body, and exposed pad for thermal performance. Pin 1 is VDD; Pin 8 is VSS (ground); unused pins (2, 4, 6) must be tied to ground per EMC recommendations.

|---|---|---|
| 1 | VDD | Main supply input (4.5–5.5 V); powers internal regulator and logic |
| 2 | Test 0 | Factory test pin; must be connected to VSS for EMC compliance |
| 3 | Switch OUT | Programmable open-drain diagnostic or switch output (0.55–4.35 V swing) |
| 4 | Not Used / OUT2 | No connection in standard version; reserved for dual-die variants only |
| 5 | OUT | Main output: ratiometric analog, PWM, or serial data depending on configuration |
| 6 | Test 1 | Factory test pin; must be connected to VSS for EMC compliance |
| 7 | VDIG | Digital supply reference for output stage; decoupling required |
| 8 | VSS | Analog/digital ground reference; critical for noise immunity and accuracy |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® IMC Sensing | Enables contactless, high-tolerance angular measurement by concentrating horizontal magnetic flux without external magnets or shielding |
| End-of-Line Programmability | Full calibration of offset, gain, clamping, linearity, and filtering via PTC-04 using only VDD/VSS/OUT pins - no additional programming hardware needed |
| Dual-Die Redundancy Option | Available in TSSOP-16 (GO package); MLX90316EDC-BCG-000-RE uses single-die SOIC-8 but shares identical firmware and calibration architecture |
| Multi-Mode Output | Single device supports analog (ratiometric), PWM (100–1000 Hz), and SPI (14-bit angle + status) - selected via EEPROM configuration, not hardware change |
| Integrated Diagnostics | Real-time monitoring of VDD/VSS integrity, watchdog timeout, and magnetic saturation with dedicated diagnostic output pin and configurable thresholds |

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-RE | TSSOP-16 dual-die package with full redundancy; 14-bit SPI-only output; higher integration of diagnostics | Targeted at ASIL-D systems requiring fault-tolerant dual-channel architecture | Select when functional safety certification (ISO 26262) mandates hardware redundancy and independent channel monitoring |
| AMS30450-1200-B12 | SOIC-8 package; 12-bit analog/PWM; no SPI interface; lower max temp (125°C vs 150°C) | Limited to non-safety-critical industrial rotary encoders and HVAC dampers | Choose for cost-sensitive designs where SPI communication and extended temperature range are unnecessary |
Compared with MLX90316EDC-BCG-000-RE, the MLX90363 offers hardware-level redundancy but sacrifices analog/PWM flexibility, while the AMS30450 lacks programmable transfer characteristics and thermal drift compensation - making MLX90316EDC-BCG-000-RE optimal for automotive applications requiring field calibration and multi-output adaptability.

FAQ
What output interfaces does the MLX90316EDC-BCG-000-RE support?
The MLX90316EDC-BCG-000-RE supports three configurable output modes stored in EEPROM: ratiometric analog voltage (0–VDD), 12-bit PWM (100–1000 Hz), or 14-bit SPI serial protocol. All modes share the same physical pin (Pin 5) and are selected during calibration using the PTC-04 programmer - no hardware modification is required to switch between them.
Does MLX90316EDC-BCG-000-RE require an external magnet?
Yes, MLX90316EDC-BCG-000-RE requires a small dipole magnet mounted on the rotating shaft (end-of-shaft configuration). The integrated magneto-concentrator (IMC) detects the horizontal component of the magnetic field, enabling accurate angular measurement without direct contact or complex magnet assemblies.
What is the maximum angular range supported by MLX90316EDC-BCG-000-RE?
The MLX90316EDC-BCG-000-RE supports a fully programmable absolute angular range up to 360°, with user-defined start and stop points, discontinuity location, and clockwise/counterclockwise orientation. This range is implemented digitally in the on-chip DSP and does not depend on magnet geometry or mechanical stops.
How is MLX90316EDC-BCG-000-RE calibrated in production?
MLX90316EDC-BCG-000-RE is calibrated end-of-line using Melexis' PTC-04 programming unit, which communicates exclusively through the VDD–VSS–OUT pins. Calibration writes parameters such as offset, gain, clamping levels, linearity coefficients, and filter settings into its 128 B EEPROM - no additional programming interface or pins are needed.
Is MLX90316EDC-BCG-000-RE qualified for automotive use?
Yes, MLX90316EDC-BCG-000-RE is AEC-Q100 qualified (Grade 0: -40°C to +150°C ambient), designed for automotive applications including steering, throttle, and brake pedal position sensing. It includes built-in diagnostics (VDD/VSS monitoring, watchdog, magnetic saturation detection) and meets EMC requirements per ISO 11452 and ISO 7637.
