Product details
Overview
MLX90316LGO-BCG-000-SP from Melexis is an absolute rotary position sensor IC using Triaxis® Hall technology to measure angular position of an end-of-shaft dipole magnet with 12-bit resolution, ±1° intrinsic linearity error, and programmable 0–360° range-used in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90316LGO-BCG-000-SP datasheet, pinout, applications, or equivalent options, key selection factors include its TSSOP-16 dual-die redundancy, -40°C to +150°C operation, ratiometric analog/PWM/serial output modes, and end-of-line programmability via PTC-04.
Technical Context
The MLX90316LGO-BCG-000-SP integrates a Triaxis® magnetic front-end with on-chip IMC to sense horizontal flux components, enabling contactless angular measurement up to 360°. Its 16-bit RISC DSP performs real-time CoRDiC-based angle calculation from sine/cosine raw ADC outputs (14-bit typical, 15-bit slow mode).
It supports three configurable output protocols: ratiometric analog (12-bit DAC), PWM (12-bit resolution, 100–1000 Hz), or 3-wire SPI (14-bit angle data). All transfer characteristics-including offset, gain, clamping, deadzone, and filtering-are programmable via VDD/VSS/OUT pins using the PTC-04 unit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Angular Resolution | 12-bit (0.0879°/LSB theoretical); 14-bit raw sine/cosine ADC enables high-precision angle computation |
| Thermal Accuracy | ±10-bit (±0.35°) over full -40°C to +150°C range due to calibrated thermal drift compensation |
| Output Modes | Ratiometric analog, PWM (100–1000 Hz), or 3-wire SPI (14-bit angle, 0.022°/LSB) |
| Linearity Error | ±1° intrinsic (IC-only); improved further via multi-point end-user calibration |
| Operating Temp | -40°C to +150°C (L-grade), qualified for under-hood automotive applications |
| Package | TSSOP-16 with dual-die full redundancy for ASIL-B functional safety compliance |
| Magnetic Range | 20–70 mT field strength; IMC saturation above 70 mT increases linearity error |
Pinout & Package
TSSOP-16 package with dual-die architecture for redundancy; RoHS-compliant, 4.4 mm × 5.0 mm footprint, 1.0 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9, 11 | VDIG1 / VDIG2 / VDD2 | Digital supply rails for independent die operation; enables fault-isolated dual-channel sensing |
| 2, 10, 16 | VSS1 / VSS2 / Test 11 | Ground reference per die and test access; unused test pins must be grounded for EMC |
| 3, 13 | VDD1 / Switch OUT1 | Main analog/digital supply and programmable switch output (open-drain, 0.55–4.35 V swing) |
| 4, 12, 14 | Test 01 / Test 02 / SCLK1 | Factory test points and SPI clock input for primary die; not user-accessible in standard operation |
| 5, 15 | OUT1 / MOSI1/MISO1 | Main analog/PWM output or bidirectional SPI data line; shares pin function depending on mode |
| 6, 7 | Test 1 / OUT2 | Secondary output (analog/PWM/SPI) enabled only on BCS variants; this part uses dual-die parallel reporting |
| 8 | /SS1 | Slave select for primary SPI interface; active-low enable for serial communication |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® + IMC Sensing | Enables robust 360° absolute angle measurement with immunity to airgap and off-axis mechanical tolerances |
| Dual-Die Redundancy | Full hardware redundancy in single TSSOP-16 package supports ASIL-B diagnostic coverage without external duplication |
| End-of-Line Programmability | All transfer characteristics (offset, gain, clamping, filtering) configured via VDD/VSS/OUT pins-no extra programming interface needed |
| Multi-Protocol Output | Single device delivers analog, PWM, or SPI output-reduces BOM count across platform variants |
| Self-Diagnostic Capability | Real-time monitoring of VDD/VSS continuity, magnetic field presence, and internal signal path integrity |

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-1AA-000 | Single-die TSSOP-16, 16-bit resolution, integrated EEPROM for factory calibration, no dual-die redundancy | Lacks hardware redundancy; suitable for ASIL-A or non-safety-critical applications | Select when higher resolution and pre-calibrated performance are prioritized over fault tolerance |
| AMS AS5055A-TS_EK | 14-bit SPI-only output, SOIC-16 package, no analog/PWM modes, requires external MCU for diagnostics | No self-contained diagnostics or programmable transfer function; relies on host processor for safety checks | Choose for cost-sensitive industrial designs where SPI interface and compact size outweigh redundancy needs |
Compared with MLX90316LGO-BCG-000-SP, the MLX90363 offers higher resolution but no dual-die fail-safe capability, while the AS5055A lacks on-chip programmability and built-in diagnostics-making the MLX90316LGO-BCG-000-SP uniquely suited for automotive safety-critical rotary sensing requiring both redundancy and field configurability.

FAQ
What is the operating temperature range of the MLX90316LGO-BCG-000-SP?
The MLX90316LGO-BCG-000-SP is rated for -40°C to +150°C ambient operation (L-grade), making it suitable for under-hood automotive locations such as throttle bodies and steering columns where thermal stress is extreme. This rating is validated per AEC-Q100 Grade 0 and applies to both electrical performance and magnetic sensitivity stability.
Does the MLX90316LGO-BCG-000-SP support functional safety standards like ISO 26262?
Yes, the MLX90316LGO-BCG-000-SP's dual-die TSSOP-16 architecture provides hardware redundancy required for ASIL-B compliance. Its self-diagnostic features-including broken VDD/VSS detection, magnetic field monitoring, and signal path validation-enable systematic fault coverage per ISO 26262 Part 5. Melexis provides FMEDA reports and safety manuals supporting integration into safety-critical ECUs.
How is the MLX90316LGO-BCG-000-SP programmed for custom transfer characteristics?
The MLX90316LGO-BCG-000-SP is programmed using the Melexis PTC-04 unit, which communicates exclusively through the VDD, VSS, and OUT pins-no additional programming interface or PCB traces required. Users configure parameters including angular range, offset, gain, clamping levels, deadzone, and filter coefficients during end-of-line calibration, storing settings in on-chip EEPROM.
What output protocols does the MLX90316LGO-BCG-000-SP support, and how are they selected?
The MLX90316LGO-BCG-000-SP supports ratiometric analog voltage, PWM (100–1000 Hz), and 3-wire SPI (14-bit angle data) outputs. Selection is made via EEPROM-programmable configuration bits-not hardware pin strapping. The same physical pins (e.g., OUT1, /SS1, SCLK1) adapt their function based on the stored mode, enabling flexible system-level interface design without board revision.
Is the MLX90316LGO-BCG-000-SP pin-compatible with other MLX90316 variants?
No-MLX90316LGO-BCG-000-SP uses the TSSOP-16 dual-die package, while SOIC-8 variants (e.g., MLX90316LDC-BCG-000-SP) have different pin count, layout, and internal architecture. Pin functions differ significantly between packages (e.g., dual VDD/VSS rails, dedicated SPI lines), so PCB redesign is required when switching between GO and DC variants.
