Product details
Overview
MLX90316KGO-BCG-200-SP from Melexis is a Triaxis® absolute rotary position sensor IC for non-contact angular measurement using an end-of-shaft dipole magnet. It delivers 12-bit analog output with ratiometric transfer, supports -40°C to +125°C operation, and features on-chip DSP processing of horizontal magnetic field components via integrated magneto-concentrator (IMC) for robust airgap tolerance in automotive throttle and steering applications.
For engineers reviewing the MLX90316KGO-BCG-200-SP datasheet, pinout, applications, or equivalent options, key selection considerations include its pre-programmed analog output mode (PPA), TSSOP-16 dual-die redundancy, 360° programmable angular range, thermal accuracy of ±10 bits over temperature, and SPI-compatible serial interface capability.
Technical Context
The MLX90316KGO-BCG-200-SP implements Triaxis® sensing using on-die VX/VY Hall elements and an integrated magneto-concentrator to detect the rotating horizontal component of magnetic flux. Its 16-bit RISC DSP performs real-time arctangent calculation and linearization, enabling full 360° absolute angle reporting.
This device operates in pre-programmed analog (PPA) mode with factory-calibrated transfer characteristics, fixed 12-bit resolution, and ratiometric output scaling. The dual-die TSSOP-16 package provides functional redundancy, isolation resistance >4 MΩ between dice, and independent VDD/VSS/VDIG domains per die for enhanced fault tolerance.
Key Specifications

| Magnetic Sensitivity | 20–70 mT operating range - optimized for small NdFeB dipole magnets at 1–3 mm airgap. |
| Package | TSSOP-16 dual-die - provides hardware-level redundancy and isolation for ASIL-B/C functional safety compliance. |
Pinout & Package
TSSOP-16 dual-die package with two independent sensor channels, each featuring dedicated power, ground, and signal terminals. Pin assignment supports redundant analog/PWM outputs and isolated SPI communication paths per die.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 11 (VDD1, VDD2) | Supply voltage input per die | Independent 4.5–5.5 V supply pins enable fault-isolated power domains for redundancy. |
| 2, 10 (VSS1, VSS2) | Ground reference per die | Dedicated ground returns prevent coupling between redundant channels and support EMC robustness. |
| 5, 15 (OUT1, OUT2) | Analog output per die | Ratiometric 0–100% VDD output with 12-bit linearity - directly interfaces to ADCs without external scaling. |
| 3, 13 (Switch OUT1, /SS1) | Digital output / SPI slave select | Configurable as diagnostic switch or SPI chip select - supports dual-channel diagnostics or daisy-chain configuration. |
| 4, 14 (SCLK, SCLK2) | SPI clock input per die | Independent clock inputs allow asynchronous or synchronized readout of both dies for time-aligned redundancy checks. |
| 7, 16 (MOSI/MISO, MOSI2/MISO2) | SPI data bidirectional per die | Full-duplex SPI interface enables firmware updates, calibration data readback, and real-time diagnostic register access. |

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-BCG-000-SP | Single-die TSSOP-16, no redundancy, SPI-only output, 14-bit serial resolution | Lacks dual-die fault tolerance; suited for non-safety-critical industrial controls | Select when cost sensitivity outweighs ASIL requirement and SPI interface suffices. |
| MLX90316KDC-BCG-200-SP | SOIC-8 single-die package, same PPA mode and specs but no isolation or redundancy | Lower pin count and footprint; limited to space-constrained non-redundant designs | Choose for compact PCB layouts where dual-die isolation is not mandated by safety goals. |
Compared with MLX90363KGO-BCG-000-SP and MLX90316KDC-BCG-200-SP, the MLX90316KGO-BCG-200-SP uniquely combines pre-programmed analog output, dual-die redundancy, and TSSOP-16 packaging - making it the only option among the three qualified for ASIL-B automotive position sensing without external safety mechanisms.

FAQ
What does the "BCG-200" suffix indicate in MLX90316KGO-BCG-200-SP?
The "BCG-200" suffix denotes Pre-Programmed Analog (PPA) configuration: factory-calibrated for ratiometric analog output with fixed 0–360° range and linear transfer characteristic. This eliminates end-of-line programming and reduces test time in high-volume automotive manufacturing. The MLX90316KGO-BCG-200-SP ships ready for immediate integration into throttle or steering sensor modules without calibration equipment.
Does MLX90316KGO-BCG-200-SP support SPI communication despite being pre-programmed for analog output?
Yes, the MLX90316KGO-BCG-200-SP retains full SPI capability via pins 4 (SCLK), 7 (MOSI/MISO), and 3 (/SS) on Die 1 and pins 14 (SCLK2), 16 (MOSI2/MISO2), and 13 (/SS1) on Die 2. SPI access enables reading diagnostic registers, verifying EEPROM contents, and performing post-deployment diagnostics - all while maintaining primary analog output functionality. The MLX90316KGO-BCG-200-SP uses SPI for internal calibration verification and fault logging.
How does the dual-die architecture in MLX90316KGO-BCG-200-SP improve functional safety compliance?
The dual-die TSSOP-16 package contains two electrically isolated sensor channels with separate VDD/VSS/VDIG domains and >4 MΩ inter-die isolation resistance. This allows cross-checking of angle outputs, detection of single-point failures, and achievement of ASIL-B metrics per ISO 26262 without external comparators. The MLX90316KGO-BCG-200-SP meets diagnostic coverage targets for steering and throttle applications through hardware-level redundancy rather than software-only checks.
What magnetic setup is required for optimal performance of MLX90316KGO-BCG-200-SP?
The MLX90316KGO-BCG-200-SP requires a diametrically magnetized dipole magnet (e.g., NdFeB) positioned end-on above the IC surface, with typical airgap of 1–3 mm and radial offset <±0.5 mm. The integrated magneto-concentrator (IMC) focuses horizontal field components, enabling robust operation despite mechanical tolerances. For MLX90316KGO-BCG-200-SP, magnet strength should be 20–70 mT at the sensor surface - verified using the Melexis MAGNETO design tool.
Can MLX90316KGO-BCG-200-SP operate in PWM or serial output modes, or is it strictly analog?
The MLX90316KGO-BCG-200-SP is pre-configured for analog output (PPA mode), but its internal architecture supports PWM and serial protocols. Output mode can be reprogrammed using the Melexis PTC-04 programmer via the SPI interface - though doing so voids the factory calibration and requires full recalibration. For production use, MLX90316KGO-BCG-200-SP delivers stable ratiometric analog output without modification, preserving its qualification for automotive safety systems.
