Product details
Overview
MLX90316KGO-BCG-200-RE 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° range in TSSOP-16 dual-die package, rated for −40°C to +125°C operation, and pre-programmed for analog ratiometric output mode - used in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90316KGO-BCG-200-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its dual-die redundancy architecture, programmable transfer characteristic, thermal accuracy of ±10 bits over temperature, SPI serial interface capability, and pre-configured PPA (Pre-programmed Analog) output mode.
Technical Context
The MLX90316KGO-BCG-200-RE implements a dual-die TSSOP-16 configuration with full hardware redundancy, enabling ASIL-B compliance in safety-critical systems. Its on-chip DSP processes raw VX/VY magnetic field components via CoRDiC algorithm to compute absolute angle with 14-bit serial output resolution.
It supports three output modes - ratiometric analog, PWM, or 3-wire SPI - all selectable via end-of-line calibration; the BCG-200 variant is factory-programmed for analog output with linear transfer, clamping, and thermal compensation enabled, eliminating need for external programming during integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Angular Resolution | 12-bit (0.0879°/LSB), noise-free theoretical resolution for analog output path |
| Thermal Angular Accuracy | ±10-bit (±0.3° typical) over −40°C to +125°C, including offset and sensitivity drift |
| Output Mode | Pre-programmed analog ratiometric (PPA), 0–100% VDD output span, 3.3 V or 5 V compatible |

| Pre-programmed Analog (PPA) | BCG-200 variant ships calibrated for ratiometric analog output with optimized thermal compensation and 0–360° linear mapping |
| Self-Diagnostic Capability | Real-time monitoring of VDD/VSS continuity, magnetic saturation, signal chain integrity, and internal memory checksums |
Applications
| Steering Wheel Position Sensing | Throttle Position Sensing |
|---|---|
Use Scenario: Installed behind vehicle steering column to detect absolute rotation angle without mechanical wear or contact. IC Role / Device Role / Timing Role: Absolute angular position transducer converting magnet rotation into ratiometric analog voltage proportional to shaft angle. Use Value: Enables precise torque overlay and lane-keeping assist by delivering <±0.3° thermal accuracy across full automotive temperature range. | Use Scenario: Mounted on engine throttle body to monitor butterfly valve opening angle in gasoline direct injection systems. IC Role / Device Role / Timing Role: Safety-relevant position feedback device providing redundant analog signals for ECU closed-loop control. Use Value: Dual-die architecture allows real-time comparison between outputs, supporting ASIL-B diagnostics without additional hardware. |

IC Role / Device Role / Timing Role: Non-contacting potentiometer replacement delivering absolute angle with immunity to dust, moisture, and mechanical wear. Use Value: IMC-based sensing maintains <±0.5° accuracy despite ±1.5 mm airgap variation - critical for adaptive damping algorithms. |
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-ABG-000-RE | Single-die TSSOP-16, 16-bit serial output, no analog/PWM, SPI-only, higher resolution (0.022°/LSB) | Targeted at digital-bus systems requiring high-resolution angle data without analog interface | Select when SPI integration is mandatory and dual-die redundancy is not required |
| MLX90316KDC-BCG-200-RE | SOIC-8 single-die package, same PPA programming, identical analog output specs but no redundancy | Suitable for cost-sensitive, space-constrained non-safety applications (e.g., industrial knobs) | Select when footprint and BOM cost are prioritized over functional safety compliance |
Compared with MLX90316KGO-BCG-200-RE, the MLX90363 offers higher angular resolution and digital-only output but lacks analog/PWM flexibility and dual-die fault tolerance; the MLX90316KDC-BCG-200-RE provides identical analog performance in smaller SOIC-8 form factor but cannot meet ASIL-B requirements due to absence of hardware redundancy.

FAQ
What output interface does the MLX90316KGO-BCG-200-RE support?
The MLX90316KGO-BCG-200-RE is pre-programmed for ratiometric analog output (0–100% VDD), with optional PWM or SPI modes accessible only after reprogramming. Its BCG-200 option code confirms factory calibration for analog mode, eliminating need for external configuration during system integration.
Does the MLX90316KGO-BCG-200-RE support functional safety standards?
Yes, the MLX90316KGO-BCG-200-RE supports ASIL-B compliance through its dual-die TSSOP-16 architecture, which enables cross-die comparison, independent diagnostic paths, and hardware-level redundancy - verified per ISO 26262 requirements for automotive safety-related systems.
What is the maximum angular range supported by the MLX90316KGO-BCG-200-RE?
The MLX90316KGO-BCG-200-RE supports a fully programmable angular range up to 360°, and the BCG-200 variant is factory-configured for full 360° linear mapping with zero-degree discontinuity point at default setting, enabling continuous rotation sensing without wraparound ambiguity.
Can the MLX90316KGO-BCG-200-RE operate with a 3.3 V supply?
Yes, the MLX90316KGO-BCG-200-RE operates with supply voltages from 4.5 V to 5.5 V, but it is ratiometric - meaning its analog output scales proportionally to VDD. When powered from a regulated 3.3 V rail, output remains valid but reduced in span; however, official specification requires minimum 4.5 V VDD per datasheet Section 6.
How is magnetic field immunity achieved in the MLX90316KGO-BCG-200-RE?
The MLX90316KGO-BCG-200-RE uses an Integrated Magneto-Concentrator (IMC) to focus ambient magnetic fields onto its Triaxis® Hall elements, rejecting orthogonal interference and enabling accurate measurement even with ±1.5 mm airgap variation or ±5° off-axis misalignment - confirmed in datasheet Sections 10 and 16.1.
