Product details
Overview
MLX90316KGO-BCG-300-SP from Melexis is a Triaxis® absolute rotary position sensor IC for end-of-shaft dipole magnet sensing, delivering 14-bit serial (SPI), 12-bit analog ratiometric, or 12-bit PWM angular output with ±0.3° thermal accuracy over -40°C to +125°C and programmable 0–360° range. It integrates IMC-based magnetic front-end, on-chip DSP, EEPROM, and diagnostics for automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90316KGO-BCG-300-SP datasheet, pinout, applications, or equivalent options, key selection criteria include TSSOP-16 dual-die redundancy, pre-programmed digital output (PPD) configuration, SPI interface timing compliance, and diagnostic coverage for ASIL-B–capable systems.
Technical Context
The MLX90316KGO-BCG-300-SP implements Triaxis® Hall sensing with integrated magneto-concentrator (IMC) to detect horizontal magnetic field components from an end-of-shaft dipole magnet. Its dual-die TSSOP-16 architecture provides full hardware redundancy, supporting functional safety requirements in automotive applications.
On-chip 16-bit RISC DSP processes raw sine/cosine ADC outputs (14-bit resolution in fast mode) into absolute angle data, then routes it via programmable output stages: 14-bit SPI (3-wire), 12-bit ratiometric analog, or 12-bit PWM. All transfer characteristics-including offset, gain, clamping, linearity, and filtering-are end-user programmable via PTC-04 through 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-BCG-300-SP | Higher 16-bit angular resolution (0.0055°/LSB), extended 0–720° range, same TSSOP-16 PPD config | Required where sub-degree precision or multi-turn capability is needed beyond single-revolution 360° | Select MLX90363KGO-BCG-300-SP when higher resolution or extended range justifies cost premium |
| AS5055A-DSOM | 14-bit SPI-only output, SOIC-8 single-die, -40°C to +125°C, no built-in diagnostics or IMC | Suitable for non-safety-critical industrial encoders where redundancy and magnetic robustness are secondary | Choose AS5055A-DSOM only if dual-die redundancy, IMC tolerance, and ASIL-B diagnostics are not required |
Compared with MLX90316KGO-BCG-300-SP, the MLX90363 offers finer resolution and wider range but shares identical PPD programming and TSSOP-16 packaging; the AS5055A lacks redundancy, IMC, and diagnostics-making it unsuitable for automotive safety-critical use despite similar SPI interface.

FAQ
What output interface does the MLX90316KGO-BCG-300-SP support?
The MLX90316KGO-BCG-300-SP is configured as Pre-programmed Digital (PPD), enabling SPI 3-wire interface only-MOSI/MISO/SCLK and /SS. Analog and PWM outputs are disabled in this variant. The device delivers 14-bit absolute angle data with 0.022°/LSB resolution and supports standard SPI timing up to 10 MHz clock rate per Melexis datasheet Rev 011.
Is the MLX90316KGO-BCG-300-SP pin-compatible with other MLX90316 variants?
No-the MLX90316KGO-BCG-300-SP uses the TSSOP-16 package with dual-die redundancy, while SOIC-8 variants (e.g., MLX90316KDC-BCG-300-SP) have different pin count, layout, and internal die architecture. Pin mapping, power domains (VDIG1/VDIG2), and diagnostic signal routing differ fundamentally; PCB redesign is required for migration between package types.
Does the MLX90316KGO-BCG-300-SP require external programming after soldering?
No-MLX90316KGO-BCG-300-SP ships with factory-programmed PPD configuration, including calibrated SPI output transfer function, clamping levels, and diagnostics settings. No end-of-line programming via PTC-04 or other tools is needed unless reconfiguration is explicitly required, preserving production throughput and calibration consistency.
What is the operating temperature range certified for the MLX90316KGO-BCG-300-SP?
The MLX90316KGO-BCG-300-SP is qualified for continuous operation from -40°C to +125°C (K-grade), validated per AEC-Q100 stress testing. Thermal angular accuracy remains within ±0.3° across this full range due to on-chip DSP compensation and dual-die matched drift characteristics-critical for under-hood automotive placement.
How does the dual-die architecture in the MLX90316KGO-BCG-300-SP improve reliability?
The MLX90316KGO-BCG-300-SP's TSSOP-16 dual-die design provides hardware-level redundancy: two independent sensor dies with separate VDD/VSS rails, signal chains, and diagnostic blocks. This enables cross-checking of angle outputs and fault isolation-meeting ASIL-B requirements without external monitoring, and sustaining operation even if one die fails catastrophically.
