Product details
Overview
MLX90316SDC-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 output modes and features programmable angular range up to 360°, linear transfer characteristic, and integrated magneto-concentrator for robust airgap tolerance in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90316SDC-BCG-000-TU datasheet, pinout, applications, or equivalent options, key selection criteria include its SOIC-8 package, 12-bit angular resolution, programmable output transfer function, dual-die redundancy option, and compatibility with PTC-04 end-of-line calibration.
Technical Context
The MLX90316SDC-BCG-000-TU integrates a Triaxis® magnetic front-end with on-chip DSP to compute absolute angular position from sine/cosine magnetic field components. Its IMC enables contactless sensing of rotating dipole magnets with high immunity to mechanical misalignment.
It supports three configurable output protocols - ratiometric analog (0–100% VDD), 12-bit PWM (100–1000 Hz), or 14-bit SPI serial - all programmable via VDD/VSS/OUT pins using the PTC-04 unit. The device includes EEPROM-stored calibration data, 40-bit ID, and diagnostics including broken-track detection.

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-ABD-000-SP | TSSOP-16 dual-die package with full redundancy; SPI-only interface; higher integration of diagnostics | Targeted at ASIL-D safety-critical systems requiring hardware-level fault containment | Select when functional safety certification (ISO 26262) and dual-channel independence are mandatory |
| AS5055A-DSOM | 14-bit resolution, SPI-only output, no analog/PWM; requires external MCU for calibration; no integrated IMC | Suitable for compact PCB layouts where magnetic design flexibility outweighs ease of integration | Select when board space is constrained and magnetic field optimization is handled externally |
Compared with MLX90316SDC-BCG-000-TU, the MLX90363 offers hardware redundancy but sacrifices analog/PWM flexibility, while the AS5055A delivers higher resolution at the cost of calibration complexity and reduced mechanical tolerance - making the MLX90316SDC-BCG-000-TU optimal for cost-sensitive, high-volume automotive position sensing with rapid time-to-market.

FAQ
What output modes does the MLX90316SDC-BCG-000-TU support?
The MLX90316SDC-BCG-000-TU supports three factory-configurable output modes: ratiometric analog (0–100% VDD), PWM (100–1000 Hz, 12-bit resolution), and 3-wire SPI serial (14-bit angular data). All modes are programmable via the PTC-04 unit using only VDD, VSS, and OUT pins - no dedicated programming interface is required. The MLX90316SDC-BCG-000-TU defaults to analog mode after power-up unless reconfigured.
Does the MLX90316SDC-BCG-000-TU require an external magnet, and what type is recommended?
Yes, the MLX90316SDC-BCG-000-TU requires an external diametrically magnetized neodymium (NdFeB) or samarium-cobalt (SmCo) dipole magnet positioned above the IC surface (end-of-shaft configuration). Recommended magnet size is Ø4 × 2 mm with Br ≥ 1.2 T; field strength at sensor surface must stay within 20–70 mT for optimal linearity. The integrated magneto-concentrator (IMC) enables operation with ±0.5 mm airgap tolerance - no external flux guides needed.
What is the angular accuracy specification of the MLX90316SDC-BCG-000-TU over temperature?
The MLX90316SDC-BCG-000-TU delivers ±1° total angular error over its full operating range of -40°C to +125°C. This includes contributions from intrinsic linearity error (±1° at 25°C), thermal offset drift (±60 LSB₁₅ ≈ ±0.3°), and thermal sensitivity mismatch (±0.3%). Accuracy is maintained without recalibration due to on-chip DSP compensation and EEPROM-stored calibration coefficients programmed during end-of-line testing.
Can the MLX90316SDC-BCG-000-TU be used in safety-critical automotive applications?
Yes - the MLX90316SDC-BCG-000-TU is AEC-Q100 Grade 0 qualified (-40°C to +125°C) and includes built-in diagnostics such as broken-VDD/VSS detection, watchdog timer, and configurable diagnostic output. While it is a single-die device, its robust magnetic sensing, programmable clamping/deadzone, and EEPROM-stored calibration support ASIL-B system integration. For ASIL-D, Melexis offers the dual-die MLX90363 in TSSOP-16 package.
How is the MLX90316SDC-BCG-000-TU calibrated, and what tools are required?
The MLX90316SDC-BCG-000-TU is calibrated end-of-line using Melexis' PTC-04 programming unit, which communicates exclusively through the VDD–VSS–OUT pins - no additional interface lines or debug headers are needed. Calibration configures angular range, transfer function (offset/gain/clamping), filtering, and diagnostics. Factory-default settings are stored in 128 B EEPROM; users can reprogram in-system via the same 3-pin interface using PTC-04 firmware v4.0 or later.
