Product details
Overview
MLX90316EDC-BDG-100-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. It delivers ratiometric analog, PWM, or 14-bit SPI output and operates from -40°C to +125°C in SOIC-8 package.
For engineers reviewing the MLX90316EDC-BDG-100-SP datasheet, pinout, applications, or equivalent options, key selection factors include its contactless magnetic sensing architecture, on-chip DSP-based angular calculation, end-of-line programmability via PTC-04, and dual-die redundancy option for safety-critical automotive position sensing.
Technical Context
The MLX90316EDC-BDG-100-SP integrates a Triaxis® Hall front-end with integrated magneto-concentrator (IMC) to detect horizontal magnetic field components, enabling robust angular measurement across mechanical airgap and off-axis tolerances. Its on-chip 16-bit RISC DSP performs real-time rectangular-to-polar conversion (CoRDiC), thermal compensation, and linearization using user-programmable LNR parameters.
This variant supports SPI serial protocol output (14-bit angle data), features EEPROM-stored calibration coefficients, and includes programmable diagnostics such as broken VDD/VSS detection and watchdog timeout. The BDG-100 suffix confirms SPI interface capability and SOIC-8 packaging with operating temperature range -40°C to +125°C (K-grade).

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 |
|---|---|---|---|
| MLX90363KDC-ABB-000-SP | Higher 16-bit resolution, integrated 3D Hall front-end, no IMC; requires external magnet calibration | Targeted at high-precision industrial servo feedback, not optimized for automotive airgap tolerance | Select when >0.01° resolution and lower thermal drift are required, accepting tighter mechanical constraints |
| AS5055A-DSOT | 12-bit SPI-only output, no analog/PWM modes; smaller TSSOP-16 package; lacks on-chip DSP linearization | Designed for space-constrained consumer robotics, not qualified for automotive AEC-Q100 Grade 0 | Select for cost-sensitive non-automotive applications where external MCU handles linearization and diagnostics |
Compared with MLX90316EDC-BDG-100-SP, the MLX90363 offers higher resolution but reduced mechanical robustness, while the AS5055A provides smaller footprint and lower cost at the expense of automotive qualification and integrated signal conditioning.

FAQ
What output interfaces does the MLX90316EDC-BDG-100-SP support?
The MLX90316EDC-BDG-100-SP supports three configurable output modes: ratiometric analog voltage (0–100% VDD), PWM (100–1000 Hz, programmable polarity and frequency), and SPI serial protocol (14-bit angle data, 3-wire interface). The BDG-100 suffix explicitly denotes SPI capability. All modes are selected and calibrated via the PTC-04 programmer using only VDD, VSS, and OUT pins - no dedicated programming interface is required. The MLX90316EDC-BDG-100-SP does not support dual-output or Switch Out functionality in this variant.
How is angular accuracy maintained across temperature for MLX90316EDC-BDG-100-SP?
MLX90316EDC-BDG-100-SP maintains angular accuracy via on-chip DSP-based thermal compensation applied to both front-end offset and sensitivity mismatch. Thermal offset drift is ±60 LSB15 (≈±0.3°) for K-grade (-40°C to +125°C), and thermal sensitivity drift is ±0.3%. These corrections are embedded in the firmware and activated during operation - no external temperature sensor or host MCU intervention is needed. The MLX90316EDC-BDG-100-SP achieves ±1.5° total angular error over full temperature range after end-of-line calibration, verified per AEC-Q100 stress testing.
Can MLX90316EDC-BDG-100-SP replace potentiometers in non-contacting applications?
Yes - the MLX90316EDC-BDG-100-SP is specifically designed as a drop-in replacement for contacting potentiometers in applications like throttle valves, pedals, and float-level sensors. Its Triaxis® IMC architecture eliminates mechanical wear, provides infinite rotational life, and tolerates ±0.5 mm airgap variation and ±2° axial misalignment. Unlike potentiometers, the MLX90316EDC-BDG-100-SP delivers absolute position on power-up with no homing sequence, and its programmable clamping and deadzone features replicate potentiometer end-stop behavior digitally. No redesign of mechanical mounting is required.
What magnet specifications are recommended for MLX90316EDC-BDG-100-SP?
Melexis recommends a diametrically magnetized NdFeB or SmCo dipole magnet (e.g., 5 mm × 2 mm cylinder) positioned 1–3 mm above the MLX90316EDC-BDG-100-SP surface, centered on the IMC region. Magnetic flux density at the die must stay within 20–70 mT - exceeding 70 mT causes IMC saturation and increased linearity error. Magnet temperature coefficient should be ≤ –2400 ppm/°C to minimize thermal drift. The MLX90316EDC-BDG-100-SP datasheet provides detailed airgap vs. field strength curves and orientation diagrams; magnet selection must be validated with the PTC-04 during end-of-line calibration.
Is MLX90316EDC-BDG-100-SP AEC-Q100 qualified?
Yes - the MLX90316EDC-BDG-100-SP is fully AEC-Q100 qualified to Grade K (-40°C to +125°C ambient), including stress tests for HTOL, TC, UHAST, ESD-HBM/MM, and EM immunity. This qualification covers the complete SOIC-8 package assembly, wafer fabrication, and final test. The "K" temperature code in the part number confirms Grade K compliance. All qualification reports are available under NDA from Melexis; Aetrix Electronics supplies only AEC-Q100 certified units with full traceability and lot-level documentation for automotive production use.
