Product details
Overview
MLX90316EDC-BCG-000-TU from Melexis is an absolute rotary position sensor IC based on Triaxis® Hall technology, delivering 12-bit angular resolution and ±1° thermal accuracy over –40°C to +125°C. It supports ratiometric analog, PWM, or serial (SPI) output modes and features programmable transfer characteristics for end-of-line calibration in steering wheel, throttle, and pedal position sensing applications.
For engineers reviewing the MLX90316EDC-BCG-000-TU datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 package mapping, real-world angular accuracy data, calibrated output flexibility, and validated alternative options for automotive and industrial position feedback systems.
Technical Context
The MLX90316EDC-BCG-000-TU integrates a monolithic Triaxis® Hall sensor with on-chip IMC (Integrated Magneto-Concentrator), enabling contactless detection of the horizontal magnetic field component from an end-of-shaft dipole magnet. Its DSP performs real-time rectangular-to-polar conversion using CoRDiC algorithms to compute absolute angle over 0–360°.
It features dual operating modes (Slow/Fast), configurable FIR/IIR filtering, programmable clamping and deadzone, and built-in diagnostics including broken-track detection. The device uses a 16-bit RISC microcontroller (5 MIPS @ 20 MHz) with 10 KB ROM, 256 B RAM, and 128 B EEPROM for user calibration storage.

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-100-SP | TSSOP-16 dual-die package with full redundancy; SPI-only interface; higher EMC immunity | Required for ASIL-D systems needing hardware-level fault containment | Select when functional safety certification (ISO 26262) mandates dual-die architecture and independent signal paths |
| AMS AS5055A-BQFT | 14-bit resolution; I²C interface only; no analog/PWM outputs; lower max temp (125°C) | Suitable for non-automotive industrial encoders where SPI compatibility is not required | Choose for cost-sensitive consumer or white-goods designs prioritizing I²C integration over multi-output flexibility |
Compared with MLX90316EDC-BCG-000-TU, the MLX90363 offers certified redundancy but sacrifices analog/PWM versatility, while the AS5055A provides higher resolution at the expense of interface flexibility and automotive qualification.

FAQ
What output interfaces does the MLX90316EDC-BCG-000-TU support?
The MLX90316EDC-BCG-000-TU supports three configurable output interfaces: ratiometric analog voltage (0–100% VDD), 12-bit PWM (100–1000 Hz), and 3-wire SPI serial (14-bit angle data). All modes are selected via EEPROM programming using the PTC-04 tool - no hardware changes are needed to switch between them. The MLX90316EDC-BCG-000-TU does not support I²C or CAN interfaces.
Is the MLX90316EDC-BCG-000-TU qualified for automotive use?
Yes, the MLX90316EDC-BCG-000-TU carries AEC-Q100 Grade 0 qualification (–40°C to +150°C ambient), is manufactured in IATF 16949-certified facilities, and meets automotive EMC standards per ISO 11452 and ISO 7637. Its K-temperature grade (–40°C to +125°C junction) and built-in diagnostics make it suitable for EPS, throttle, and brake-by-wire applications. The MLX90316EDC-BCG-000-TU also includes EEPROM CRC and startup self-test for functional safety alignment.
How is angular calibration performed on the MLX90316EDC-BCG-000-TU?
Calibration is performed end-of-line using Melexis' PTC-04 programming unit, which communicates exclusively through the MLX90316EDC-BCG-000-TU's VDD, VSS, and OUT pins - no dedicated programming interface is required. Users configure offset, gain, linearity (via 3-point LNR), clamping, deadzone, and filter settings, then store them in the device's 128 B EEPROM. The MLX90316EDC-BCG-000-TU retains all settings after power cycle and supports lock/unlock via MLXLOCK and LOCK bits.
What is the maximum allowable magnetic field strength for the MLX90316EDC-BCG-000-TU?
The MLX90316EDC-BCG-000-TU operates linearly within ±70 mT magnetic flux density. Above this level, the Integrated Magneto-Concentrator (IMC) saturates, increasing intrinsic linearity error beyond specification. The device remains functional up to ±700 mT absolute maximum rating, but angular accuracy degrades significantly above 70 mT. For optimal performance, the MLX90316EDC-BCG-000-TU requires a dipole magnet sized and positioned to deliver 20–50 mT at the die surface under worst-case airgap and temperature conditions.
Does the MLX90316EDC-BCG-000-TU support dual-output functionality?
No, the MLX90316EDC-BCG-000-TU (SOIC-8, BCG-000 variant) supports only a single main output (OUT pin, Pin 5) and one Switch OUT (Pin 3). Dual-output capability (OUT1 + OUT2) is exclusive to the MLX90316xDC-BCS variant in TSSOP-16 package. The MLX90316EDC-BCG-000-TU's Pin 4 is unconnected and must be grounded; it does not function as a second output channel.
