Product details
Overview
MLX90316SDC-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 supports ratiometric analog, PWM, or serial (SPI) output modes and features programmable transfer characteristics including offset, gain, clamping, and linearity-calibrated via PTC-04 using only VDD/VSS/OUT pins. Used in automotive throttle and steering wheel position sensing where contactless robustness against airgap and off-axis tolerances is critical.
For engineers reviewing the MLX90316SDC-BCG-000-RE datasheet, pinout, applications, or equivalent options, key selection factors include its SOIC-8 package, 360° programmable angular range, integrated magneto-concentrator (IMC), dual-die redundancy option, and end-of-line programmability of diagnostics, filtering, and output transfer functions.
Technical Context
The MLX90316SDC-BCG-000-RE implements a monolithic Triaxis® architecture with on-chip IMC that senses the horizontal magnetic field component from an end-of-shaft dipole magnet. Its DSP performs real-time rectangular-to-polar conversion (CoRDiC) and applies user-programmable linearization, clamping, and deadzone correction before output generation.
It operates in two speed modes: slow mode (7 MHz clock, 600 μs sampling) for high-accuracy static positioning, and fast mode (20 MHz clock, 200 μs sampling) for dynamic shaft tracking. All output modes-ratiometric analog, 12-bit PWM, or 14-bit SPI-are selectable and configurable via EEPROM without hardware changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Angular Resolution | 12-bit (0.0879°/LSB), enabling precise shaft angle quantization for closed-loop motor control. |
| Thermal Accuracy | ±1° over full temperature range (-40°C to +125°C), achieved via calibrated DSP offset/sensitivity drift compensation. |
| Output Modes | Ratiometric analog (0–100% VDD), 12-bit PWM (100–1000 Hz), or 14-bit SPI (3-wire serial), all software-selectable. |
| Programmable Range | 0–360° absolute rotation, with discontinuity point and clockwise/counter-clockwise direction configurable. |
| Magnetic Sensitivity | Operates with 20–70 mT dipole field; IMC enables robust performance across ±0.5 mm airgap and ±1 mm lateral misalignment. |
| Supply & Current | 4.5–5.5 V nominal supply; 8.5–16 mA current draw depending on speed mode-optimized for low-power automotive modules. |
| Diagnostic Capability | Integrated diagnostics include broken VDD/VSS detection, watchdog timeout, and programmable fault thresholds per output channel. |
Pinout & Package
MLX90316SDC-BCG-000-RE is housed in an RoHS-compliant SOIC-8 package (5.3 mm × 6.2 mm × 1.75 mm). Pin assignments are validated per Melexis datasheet Rev. 011, Section 4 (Pinout), and optimized for EMC with unused pins tied to ground.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Main power supply input (4.5–5.5 V); powers analog front-end, DSP, and output stage. |
| 2 | Test 0 | Factory test pin; must be connected to VSS for normal operation per datasheet recommendation. |
| 3 | Switch OUT | Programmable digital switch output (open-drain), configurable as diagnostic flag or position threshold indicator. |
| 4 | Not Used / OUT2 | No connection in standard SOIC-8 single-die version; reserved for dual-die TSSOP-16 variant only. |
| 5 | OUT | Primary output terminal: delivers ratiometric analog voltage, PWM signal, or SPI MISO data depending on configuration. |
| 6 | Test 1 | Factory test pin; must be connected to VSS for normal operation per datasheet recommendation. |
| 7 | VDIG | Digital supply rail for internal logic; internally regulated from VDD and decoupled externally. |
| 8 | VSS | Analog/digital ground reference; requires low-impedance connection to system ground for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® IMC Sensing | Enables contactless 360° angular measurement with immunity to mechanical tolerances (airgap, off-axis, tilt) up to ±0.5 mm. |
| End-of-Line Programmability | Full transfer function (offset, gain, clamping, linearity, filtering) configured via PTC-04 using only VDD/VSS/OUT pins-no extra programming interface required. |
| Dual Speed Operation | Slow mode (7 MHz) maximizes resolution and thermal stability; fast mode (20 MHz) reduces latency to 200 μs for dynamic applications like pedal position feedback. |
| Multi-Mode Output | Single device supports analog (ratiometric), PWM (12-bit), or SPI (14-bit) outputs-eliminates BOM variants for different system interfaces. |
| On-Chip Diagnostics | Real-time monitoring of supply faults (broken VDD/VSS), watchdog timeout, and configurable error flags-meets ASIL-B functional safety requirements. |

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 | TSSOP-16 dual-die package with full hardware redundancy; higher temperature rating (+150°C); SPI-only output. | Required for ASIL-D systems needing fault-tolerant dual-channel architecture and extended thermal range. | Select when functional safety mandates hardware redundancy and operating beyond +125°C. |
| AS5055A-DSOT | 14-bit resolution, 3.3 V supply, I²C interface only; no analog/PWM output; lower max temperature (+125°C). | Suitable for space-constrained consumer or industrial encoders where I²C bus integration is preferred over analog/PWM flexibility. | Choose for cost-sensitive non-automotive designs requiring higher resolution but accepting single-output interface and narrower supply range. |
Compared with MLX90316SDC-BCG-000-RE, the MLX90363 offers hardware redundancy and extended temperature capability at the cost of larger footprint and SPI-only interface, while the AS5055A provides higher resolution and smaller package but lacks analog/PWM versatility and automotive-grade diagnostics.

FAQ
What output modes does the MLX90316SDC-BCG-000-RE support?
The MLX90316SDC-BCG-000-RE supports three configurable output modes: ratiometric analog voltage (0–100% VDD), 12-bit PWM (100–1000 Hz), and 14-bit SPI serial communication (3-wire interface). Mode selection is stored in EEPROM and persists after power cycle. The MLX90316SDC-BCG-000-RE does not require external components to switch between modes-configuration is performed once via PTC-04 programmer using only VDD, VSS, and OUT pins.
How is the MLX90316SDC-BCG-000-RE calibrated for specific mechanical setups?
The MLX90316SDC-BCG-000-RE supports full end-of-line calibration using the Melexis PTC-04 programming unit. Users can program angular range (0–360°), discontinuity point, linear transfer parameters (slope, offset, clamping), deadzone, and filtering coefficients-all stored in on-chip EEPROM. Calibration uses only the standard VDD/VSS/OUT pins, eliminating need for dedicated programming headers. The MLX90316SDC-BCG-000-RE retains all settings across power cycles and operates immediately upon power-up with calibrated behavior.
What is the operating temperature range of the MLX90316SDC-BCG-000-RE?
The MLX90316SDC-BCG-000-RE is rated for operation from -40°C to +125°C ambient temperature, matching the 'K' temperature suffix in its ordering code. This range is validated per AEC-Q100 Grade 0 requirements and includes full specification compliance for angular accuracy (±1°), supply current, and output performance. The MLX90316SDC-BCG-000-RE maintains functionality across this range without derating, making it suitable for under-hood automotive applications such as throttle and pedal position sensing.
Does the MLX90316SDC-BCG-000-RE include built-in diagnostics?
Yes, the MLX90316SDC-BCG-000-RE integrates multiple diagnostics: broken VDD/VSS detection, watchdog timeout monitoring, and programmable fault flags on Switch OUT. Diagnostic thresholds (e.g., clamping levels, hysteresis) are user-configurable via EEPROM. These features enable ASIL-B compliance in automotive systems without external monitoring circuitry. The MLX90316SDC-BCG-000-RE reports faults through dedicated output states or SPI register reads, supporting fail-safe system responses.
What package type is used for the MLX90316SDC-BCG-000-RE?
The MLX90316SDC-BCG-000-RE uses a RoHS-compliant SOIC-8 surface-mount package (5.3 mm × 6.2 mm × 1.75 mm). This single-die configuration supports analog, PWM, and SPI outputs in a compact footprint. Unlike dual-die TSSOP-16 variants, the SOIC-8 version has no second output (OUT2) and uses pins 2 and 6 as Test 0/Test 1-both must be grounded per Melexis design guidelines. The MLX90316SDC-BCG-000-RE's package is qualified for reflow soldering per J-STD-020 and supports automotive-grade thermal cycling reliability.
