Product details
Overview
MLX90316KDC-BCG-300-TU from Melexis is a Triaxis® absolute rotary position sensor IC for end-of-shaft dipole magnet sensing, delivering 12-bit angular resolution, programmable 0–360° range, and ratiometric analog/PWM/serial output modes in SOIC-8 package with -40°C to +125°C operating range. It enables non-contact throttle, pedal, and steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90316KDC-BCG-300-TU datasheet, pinout, applications, or equivalent options, key selection criteria include its pre-programmed digital (PPD) configuration, Triaxis® IMC-based horizontal flux sensing, 10-bit thermal angular accuracy, 40-bit unique ID, and SPI-compatible serial interface with 14-bit angle data.
Technical Context
The MLX90316KDC-BCG-300-TU integrates a Triaxis® Hall sensor with on-die Integrated Magneto-Concentrator (IMC) to detect the rotating horizontal component of magnetic flux from an end-of-shaft dipole magnet. Its monolithic SOIC-8 die performs real-time DSP-based angular calculation using CoRDiC algorithms on raw sine/cosine ADC outputs (15-bit slow mode, 14-bit fast mode).
It supports three output modes-ratiometric analog (12-bit DAC), PWM (12-bit, 100–1000 Hz), or serial protocol (14-bit angle over 3-wire SPI)-all programmable via VDD/VSS/OUT pins using PTC-04. The BCG-300 variant is factory pre-programmed for digital output with default clamping, filtering, and transfer characteristics optimized for robust deployment without end-of-line calibration.

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-ABG-000-RE | Dual-die TSSOP-16 package with full hardware redundancy; supports ASIL-D; includes second independent output channel | Required for dual-channel safety architectures (e.g., ISO 26262 ASIL-D steering angle); higher pin count and cost | Select when functional safety requires hardware redundancy and fault-tolerant dual-output capability |
| MLX90316KDC-BCG-200-TU | Same SOIC-8 package and K-temp grade but pre-programmed for analog output (PPA); 12-bit ratiometric voltage output instead of SPI | Suitable for legacy analog ECU inputs; lacks digital diagnostics and configurability of serial mode | Choose for cost-sensitive analog interface designs where microcontroller SPI resources are unavailable |
Compared with MLX90316KDC-BCG-300-TU, the MLX90363 offers hardware redundancy for highest safety integrity, while MLX90316KDC-BCG-200-TU trades digital flexibility for simpler analog integration-neither is pin-compatible, and all require distinct PCB layout and firmware support.

FAQ
What output interface does the MLX90316KDC-BCG-300-TU support?
The MLX90316KDC-BCG-300-TU is pre-programmed for digital output only: it delivers 14-bit absolute angle data exclusively via its 3-wire SPI interface (MOSI/MISO, /SS, SCLK not used on SOIC-8). Analog and PWM outputs are disabled in this PPD (Pre-Programmed Digital) configuration, and no end-of-line calibration is required.
Does the MLX90316KDC-BCG-300-TU require external programming before use?
No, the MLX90316KDC-BCG-300-TU ships fully configured as a Pre-Programmed Digital (PPD) device. All parameters-including output mode, clamping levels, filter settings (FILTER=5), and diagnostic thresholds-are factory-set. It operates immediately upon power-up with SPI communication enabled; no PTC-04 programmer or calibration step is needed.
What is the operating temperature range of the MLX90316KDC-BCG-300-TU?
The MLX90316KDC-BCG-300-TU is rated for continuous operation from -40°C to +125°C (K-grade), meeting AEC-Q100 Grade 0 requirements. Its thermal angular accuracy remains within ±0.35° over this full range due to integrated compensation for offset drift and sensitivity mismatch in the on-chip DSP.
How does the Triaxis® IMC technology improve mechanical tolerance in the MLX90316KDC-BCG-300-TU?
The Integrated Magneto-Concentrator (IMC) on the MLX90316KDC-BCG-300-TU die focuses and enhances the horizontal component of magnetic flux, enabling accurate angular measurement despite ±0.5 mm airgap variation or ±2° axial misalignment. This eliminates need for tight mechanical tolerancing in throttle or pedal assemblies.
Is the MLX90316KDC-BCG-300-TU pin-compatible with other MLX90316 variants in SOIC-8 package?
Yes, all MLX90316 variants in SOIC-8 (e.g., BCG-000, BCG-200, BCG-300) share identical pinout and footprint. However, functionality differs: BCG-300 enables SPI only, BCG-200 enables analog output, and BCG-000 is unprogrammed. Firmware and PCB design must match the specific variant's output mode and default settings.
