Product details
Overview
MLX90316SDC-BCG-000-SP from Melexis is an absolute rotary position sensor IC based on Triaxis® Hall technology, delivering 12-bit angular resolution and programmable 0–360° angular range in SOIC-8 package. It outputs ratiometric analog, PWM, or serial data via SPI interface, with integrated magneto-concentrator enabling robust contactless sensing of end-of-shaft dipole magnets under mechanical airgap and off-axis tolerances.
For engineers reviewing the MLX90316SDC-BCG-000-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its programmable transfer characteristic (offset, gain, clamping), thermal accuracy (±10-bit over temperature), dual-die redundancy option, and support for automotive-grade operation up to +125°C.
Technical Context
The MLX90316SDC-BCG-000-SP integrates a Triaxis® magnetic front-end with on-chip DSP and 16-bit RISC microcontroller, processing VX/VY sine/cosine signals into absolute angle with 0.022°/LSB resolution in serial mode. Its IMC-enhanced sensing enables high immunity to mechanical misalignment while maintaining ±1° intrinsic linearity error at 25°C.
It supports three output modes-ratiometric analog (12-bit DAC), PWM (12-bit, 100–1000 Hz), and 14-bit SPI serial-with full end-of-line programmability of transfer function, filtering (FIR/IIR), diagnostics, and clamping levels via PTC-04 programmer using only VDD/VSS/OUT pins.

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 | Dual-die TSSOP-16 package with full hardware redundancy; higher current draw (2× IDD); supports ASIL-D ready architecture | Required for dual-channel fault-tolerant systems (e.g., steer-by-wire); not pin-compatible with SOIC-8 | Select when system-level functional safety requires hardware redundancy and diagnostic coverage >90% |
| AMS30451-2000-SOIC8 | Single-die Hall-based rotary sensor; 10-bit resolution; fixed 0–180° range; no SPI interface; lower thermal accuracy (±2°) | Suitable for cost-sensitive non-safety-critical applications (e.g., industrial knobs, HVAC dampers) | Choose for simplified BOM where programmability, full 360° range, and automotive qualification are not required |
Compared with MLX90316SDC-BCG-000-SP, the MLX90363 offers hardware redundancy at the expense of layout space and power, while the AMS30451 trades resolution, range, and programmability for lower unit cost and simpler calibration.

FAQ
What output interfaces does the MLX90316SDC-BCG-000-SP support?
The MLX90316SDC-BCG-000-SP supports three configurable output interfaces: ratiometric analog voltage (0–100% VDD), PWM signal (100–1000 Hz, 12-bit resolution), and 14-bit SPI serial protocol. All modes are selected and calibrated via on-chip EEPROM using the PTC-04 programmer - no hardware changes are needed to switch between them. The MLX90316SDC-BCG-000-SP does not support I²C or CAN interfaces.
Is the MLX90316SDC-BCG-000-SP qualified for automotive applications?
Yes, the MLX90316SDC-BCG-000-SP carries AEC-Q100 Grade 0 qualification (−40°C to +125°C) and is designed for ASIL-B functional safety compliance. It includes integrated diagnostics such as VDD/VSS continuity detection, magnetic saturation monitoring, and signal-path fault reporting - all programmable via EEPROM. The MLX90316SDC-BCG-000-SP has been deployed in production steering angle and throttle position sensors since 2015.
How is the angular range programmed on the MLX90316SDC-BCG-000-SP?
The angular range of the MLX90316SDC-BCG-000-SP is fully programmable from 0° to 360° using Melexis' PTC-04 programming unit, which communicates exclusively through the VDD, VSS, and OUT pins. Users define start/end points, discontinuity location, and linear or multi-point transfer characteristics via EEPROM parameters including CLOCKWISE, DP, LNR_A/B/C coordinates, and CLAMP_HIGH/LOW. The MLX90316SDC-BCG-000-SP retains calibration data even after power cycling.
Does the MLX90316SDC-BCG-000-SP require an external magnet?
Yes, the MLX90316SDC-BCG-000-SP requires an external diametrically magnetized dipole magnet positioned above the IC surface (end-of-shaft configuration). It operates optimally with 20–70 mT field strength; fields above 70 mT cause IMC saturation and increased linearity error. The MLX90316SDC-BCG-000-SP's integrated magneto-concentrator eliminates need for flux concentrators or shielding in most mechanical layouts.
What is the supply current consumption of the MLX90316SDC-BCG-000-SP?
The MLX90316SDC-BCG-000-SP draws 8.5–11 mA in slow mode (600 μs sampling interval) and 13.5–16 mA in fast mode (200 μs sampling interval) at VDD = 5 V and TA = 25°C. Current scales linearly with temperature and supply voltage. The MLX90316SDC-BCG-000-SP includes automatic gain control and programmable filter settings that influence dynamic current draw during transient events.
