Product details
Overview
MLX90316KDC-BDG-100-SP from Melexis is an absolute rotary position sensor IC based on Triaxis® Hall technology, delivering 12-bit angular resolution and ±10-bit thermal accuracy over -40°C to +125°C. It supports programmable 0–360° angular range, ratiometric analog, PWM, or SPI serial output, and operates in SOIC-8 package with integrated magneto-concentrator for robust airgap tolerance in automotive throttle and steering applications.
For engineers reviewing the MLX90316KDC-BDG-100-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its SPI-enabled output mode (BDG-100), dual-die redundancy readiness, programmable transfer characteristic, and AEC-Q100-compliant operation across extended temperature range.
Technical Context
The MLX90316KDC-BDG-100-SP implements a monolithic Triaxis® sensing architecture with integrated magneto-concentrator (IMC) to detect horizontal magnetic field components from an end-of-shaft dipole magnet. Its on-chip 16-bit RISC DSP performs real-time arctangent computation and digital signal processing for absolute angle extraction.
Configured as SPI version (BDG-100), it uses MOSI/MISO/SCLK/SS pins for 14-bit angular data readout at up to 1 kHz update rate, with programmable filtering (FILTER=0–5), clamping, deadzone, and diagnostic settings stored in 128 B EEPROM. The device supports fast mode (20 MHz clock, 200 µs sampling) and slow mode (7 MHz, 600 µs sampling) via HIGHSPEED bit control.

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 | Single-die SOIC-8 with analog/PWM output only; no SPI interface; lower max temperature (125°C same, but no L-grade option) | Lacks serial protocol support; requires external ADC or PWM decoder; suitable for cost-sensitive non-safety designs | Select when SPI is unnecessary and analog/PWM suffices with identical mechanical footprint |
| MLX90375KGO-ABB-100-SP | Dual-die TSSOP-16 package with full hardware redundancy; SPI interface; higher current draw (2× IDD); larger footprint | Designed for ASIL-D systems requiring fault-tolerant dual-channel operation; not pin-compatible with SOIC-8 | Select when functional safety mandates hardware redundancy and board space permits TSSOP-16 |
Compared with MLX90316KDC-BDG-100-SP, MLX90363KDC-ABB-000-SP offers lower system cost without serial capability, while MLX90375KGO-ABB-100-SP provides certified fault tolerance at the expense of PCB area and power - making the MLX90316KDC-BDG-100-SP optimal for SPI-based ASIL-B designs in constrained SOIC-8 layouts.

FAQ
What output modes does the MLX90316KDC-BDG-100-SP support?
The MLX90316KDC-BDG-100-SP supports SPI serial protocol exclusively (per BDG-100 option code), delivering 14-bit absolute angle data over MOSI/MISO/SCLK/SS pins. It does not support analog or PWM outputs - those require BCG-000 or BCS-000 variants. Configuration is retained in 128 B EEPROM and accessible only via Melexis PTC-04 programmer or compatible host controller.
Is the MLX90316KDC-BDG-100-SP pin-compatible with other MLX90316 variants in SOIC-8?
Yes, all SOIC-8 MLX90316 variants (including MLX90316KDC-BDG-100-SP, MLX90316KDC-BCG-000-SP, and MLX90316KDC-BCS-000-SP) share identical pinout and footprint. However, pin functionality differs: BDG-100 configures pins 3–5 for /SS, SCLK, and MOSI/MISO, whereas BCG-000 uses them for Switch Out, OUT2, and OUT. Always verify function mapping per option code.
What is the maximum update rate for angular data from the MLX90316KDC-BDG-100-SP?
The MLX90316KDC-BDG-100-SP achieves up to 5 kHz effective update rate in fast mode (20 MHz clock, 200 µs sampling interval), though SPI frame transmission limits practical throughput to ~1–2 kHz depending on bus speed and frame size. Datasheet specifies 14-bit angle data latency of <1 ms from magnetic change to valid SPI readout under typical conditions.
Does the MLX90316KDC-BDG-100-SP include built-in diagnostics?
Yes, the MLX90316KDC-BDG-100-SP integrates diagnostics for broken VDD/VSS detection, magnetic saturation monitoring, EEPROM integrity checks, and register consistency validation. Diagnostic status is reported via dedicated bits in SPI response frames and can trigger configurable fault outputs - critical for ISO 26262 ASIL-B compliance in automotive applications.
Can the MLX90316KDC-BDG-100-SP be calibrated in-system after soldering?
Yes, the MLX90316KDC-BDG-100-SP supports full end-of-line calibration via its VDD/VSS/OUT pins using Melexis PTC-04 programmer - no additional interface required. Calibration parameters (offset, gain, clamping, linearity, filter coefficients) are written to EEPROM and persist across power cycles. SPI interface allows runtime readback but not reprogramming post-calibration.
