Product details
Overview
MLX90316KGO-BCG-300-RE from Melexis is a Triaxis® absolute rotary position sensor IC for end-of-shaft magnet configurations, delivering 14-bit serial output resolution (0.022°/LSB), ±1° intrinsic linearity error at 25°C, and operation over –40°C to +125°C. It integrates an on-die DSP, EEPROM, and programmable analog/PWM/serial output modes, used in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90316KGO-BCG-300-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its TSSOP-16 dual-die redundancy, pre-programmed digital (PPD) configuration, 360° angular range, and SPI-compatible 3-wire serial interface with 14-bit angle data.
Technical Context
The MLX90316KGO-BCG-300-RE implements Triaxis® Hall technology with an integrated magneto-concentrator (IMC) to sense the horizontal magnetic field component of a rotating dipole magnet. Its on-chip 16-bit RISC DSP performs real-time rectangular-to-polar conversion and applies user-programmable transfer characteristics including offset, gain, clamping, and filtering.
This variant uses a dual-die TSSOP-16 package with full hardware redundancy, isolated die-to-die isolation resistance ≥4 MΩ, and supports only serial protocol output mode via MOSI/MISO/SCLK pins. The PPD (Pre-programmed Digital) option fixes output as 14-bit SPI angle data with factory-calibrated linear transfer characteristic and no analog or PWM outputs enabled.

Applications
| Steering Wheel Position Sensing | Throttle Position Sensing |
|---|---|
Use Scenario: Non-contact angular measurement of steering column rotation in EPS systems under vibration, temperature cycling, and EMI exposure. IC Role / Device Role / Timing Role: Absolute rotary position sensor providing primary angle feedback to EPS controller via SPI interface. Use Value: Dual-die redundancy ensures fail-operational behavior; PPD configuration guarantees deterministic 14-bit digital output without post-manufacturing calibration. | Use Scenario: Accurate pedal angle detection in drive-by-wire throttle bodies where mechanical wear and contamination must be avoided. IC Role / Device Role / Timing Role: Contactless angular transducer reporting throttle plate position to engine control unit via SPI. Use Value: Triaxis® IMC tolerance to airgap variation (±0.5 mm) eliminates need for precision magnet mounting; 0.022°/LSB resolution supports closed-loop torque control. |
| Pedal Position Sensing | Ride Height Adjustment |
Use Scenario: Brake or accelerator pedal angle measurement in commercial vehicles requiring long-term stability and high EMC immunity. IC Role / Device Role / Timing Role: Redundant absolute position sensor feeding dual-channel safety MCU with synchronized SPI angle data. Use Value: Dual-die architecture enables cross-checking between outputs; PPD mode removes analog noise susceptibility inherent in ratiometric outputs. | Use Scenario: Suspension height feedback in adaptive air ride systems exposed to wide thermal gradients and road shock. IC Role / Device Role / Timing Role: Robust rotary sensor detecting suspension arm rotation to calculate vehicle ride height. Use Value: –40°C to +125°C operation covers under-hood environments; ±1° intrinsic linearity allows accurate height mapping without multi-point field 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-BCG-300-RE | Higher 16-bit angular resolution (0.0055°/LSB), extended 360° range, same TSSOP-16 dual-die PPD configuration | Required for sub-0.1° closed-loop motor control; not drop-in due to different EEPROM layout and calibration structure | Select when higher resolution and tighter thermal drift (<±0.2° over temp) are mandatory |
| AS5055A-DSOT | Single-die 14-bit SPI encoder, SOIC-8, no redundancy, lower operating temp (–40°C to +125°C), no IMC-based robustness | Suitable for cost-sensitive non-safety applications; lacks dual-die fault tolerance and airgap insensitivity | Choose for space-constrained PCBs where redundancy and mechanical tolerance are secondary |
Compared with MLX90316KGO-BCG-300-RE, MLX90363KGO-BCG-300-RE delivers finer angular quantization and improved thermal stability but requires updated firmware and calibration workflow, while AS5055A-DSOT offers footprint compatibility at the expense of functional safety compliance and magnetic tolerance.

FAQ
What output interface does the MLX90316KGO-BCG-300-RE support?
The MLX90316KGO-BCG-300-RE supports only the serial protocol output mode via a 3-wire SPI interface (MOSI/MISO/SCLK), delivering 14-bit angle data. Analog and PWM outputs are disabled in this PPD (Pre-programmed Digital) variant. The device uses dual-die TSSOP-16 pinout with separate MISO lines (OUT1/OUT2) and dedicated diagnostic switch outputs (Switch OUT1/Switch OUT2) per die.
Is the MLX90316KGO-BCG-300-RE pin-compatible with other MLX90316 variants?
No - the MLX90316KGO-BCG-300-RE uses the TSSOP-16 dual-die package, while SOIC-8 variants (e.g., MLX90316KDC-BCG-300-RE) have different pin count, pin functions, and no redundancy. TSSOP-16 pinout is consistent across GO-package MLX90316 versions, but PPD configuration disables certain pins (e.g., OUT, SCLK2) versus standard or SPI75AGC variants.
Does the MLX90316KGO-BCG-300-RE require external programming after soldering?
No - the MLX90316KGO-BCG-300-RE is shipped with factory-programmed PPD configuration: fixed 14-bit SPI output, calibrated linear transfer characteristic, and pre-loaded EEPROM parameters. No end-of-line calibration or programming via PTC-04 is needed unless reconfiguration is required, which would void the PPD guarantee.
What is the angular accuracy of the MLX90316KGO-BCG-300-RE over temperature?
The MLX90316KGO-BCG-300-RE exhibits ±1° intrinsic linearity error at 25°C. Over –40°C to +125°C, total angular error includes thermal offset drift (±60 LSB15 ≈ ±0.3°) and sensitivity mismatch drift (±0.3%), contributing up to ±0.4° additional error. Full system accuracy depends on magnet placement, airgap, and mechanical tolerances.
How does the dual-die architecture improve reliability in the MLX90316KGO-BCG-300-RE?
The dual-die TSSOP-16 package in the MLX90316KGO-BCG-300-RE provides hardware-level redundancy: two independent sensor dies with ≥4 MΩ isolation monitor the same magnetic field and report angle data separately. This enables cross-die comparison for fault detection and supports ASIL-B/C safety goals in automotive applications without requiring external watchdog circuitry.
