Product details
Overview
MLX90316LDC-BDG-102-SP from Melexis is an absolute rotary position sensor IC using Triaxis® Hall technology with integrated magneto-concentrator (IMC), delivering 12-bit angular resolution and programmable 0–360° angular range in SOIC-8 package. It supports ratiometric analog, PWM, or SPI serial output modes and operates across -40°C to +150°C for automotive throttle, pedal, and steering wheel position sensing.
For engineers reviewing the MLX90316LDC-BDG-102-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its SPI75AGC front-end configuration, dual-die isolation capability (not applicable to this SOIC-8 variant), programmable transfer characteristic, thermal accuracy of ±10 bits over temperature, and diagnostic features including broken-track detection and watchdog timing.
Technical Context
The MLX90316LDC-BDG-102-SP implements a monolithic Triaxis® architecture with on-chip DSP processing raw VX/VY magnetic field components into absolute angle data. Its IMC enables robust operation under mechanical tolerances including airgap variation and off-axis magnet misalignment.
This variant uses the SPI75AGC option (BDG-102), enabling automatic radius gain compensation at startup and optimized AGC loop response for dynamic magnetic field conditions. It supports 14-bit serial protocol output (0.022°/LSB), 12-bit analog/PWM outputs, and full end-of-line programmability of clamping, linearity, deadzone, and diagnostic thresholds via PTC-04 programmer.

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; higher current draw (2× IDD); isolated die-to-die resistance >4 MΩ | Required for ASIL-D systems needing hardware redundancy; not pin-compatible with SOIC-8 | Select when functional safety mandates dual-channel independence and fault containment. |
| AS5055A-DSOT | 14-bit SPI-only output; no analog/PWM; lower temp grade (-40°C to +125°C); different magnetic sensitivity (15–65 mT) | Used in industrial encoders where SPI interface suffices and cost optimization is prioritized over multi-mode flexibility | Choose if system already uses SPI infrastructure and does not require analog/PWM fallback or extended temperature range. |
Compared with MLX90316LDC-BDG-102-SP, the MLX90363 offers hardware redundancy at the cost of larger footprint and doubled supply current, while the AS5055A trades multi-output flexibility and extended temperature rating for lower unit cost and simpler SPI integration.

FAQ
What output modes does the MLX90316LDC-BDG-102-SP support?
The MLX90316LDC-BDG-102-SP supports three configurable output modes: ratiometric analog voltage (0–100% VDD), PWM (100–1000 Hz), and 3-wire SPI serial protocol delivering 14-bit angle data. Mode selection is programmed via EEPROM and persists after power cycle. The MLX90316LDC-BDG-102-SP defaults to analog mode unless reconfigured using the Melexis PTC-04 programming unit.
How does the SPI75AGC feature in MLX90316LDC-BDG-102-SP improve performance?
The SPI75AGC feature in MLX90316LDC-BDG-102-SP enables automatic radius gain compensation at startup, adjusting front-end amplification to maintain optimal signal-to-noise ratio when magnet radial distance varies. This ensures consistent angular accuracy across mechanical tolerances without requiring manual calibration. The MLX90316LDC-BDG-102-SP applies this setting during initialization and retains it in EEPROM for repeatable behavior.
What is the maximum operating temperature for MLX90316LDC-BDG-102-SP?
The MLX90316LDC-BDG-102-SP is rated for continuous operation from -40°C to +150°C ambient temperature, meeting automotive under-hood requirements. This L-grade qualification is confirmed in the Absolute Maximum Ratings table (Page 9) and Electrical Specifications (Page 10) of the official Melexis datasheet revision 011. The MLX90316LDC-BDG-102-SP maintains specified angular accuracy and diagnostic functionality across this full range.
Can MLX90316LDC-BDG-102-SP be used without external programming?
Yes, the MLX90316LDC-BDG-102-SP ships with factory-default settings enabling immediate use in analog output mode with 0–360° range and linear transfer. However, full utilization of its programmability - including clamping, linearity correction, filter tuning, and SPI configuration - requires the Melexis PTC-04 programmer. The MLX90316LDC-BDG-102-SP retains all user-programmed parameters in non-volatile EEPROM.
Does MLX90316LDC-BDG-102-SP include built-in diagnostics?
Yes, the MLX90316LDC-BDG-102-SP integrates multiple diagnostics: broken-VDD/VSS detection, watchdog timer (5 ms timeout), configurable diagnostic bands, and programmable clamping thresholds. These features support ISO 26262 ASIL-B compliance when implemented per Melexis application notes. All diagnostics operate autonomously within the MLX90316LDC-BDG-102-SP without host processor intervention.
