Product details
Overview
MLX90316KDC-BCG-200-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 ratiometric analog output with pre-programmed linear transfer characteristic (PPA option), operates in SOIC-8 package, and is used in automotive throttle and pedal position sensing where contactless, high-reliability angular measurement is required.
For engineers reviewing the MLX90316KDC-BCG-200-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its PPA (pre-programmed analog) configuration, SOIC-8 footprint, integrated IMC for robust airgap tolerance, programmable clamping and linearity, and built-in diagnostics for functional safety compliance.
Technical Context
The MLX90316KDC-BCG-200-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 DSP processes raw sine/cosine signals (15-bit ADC in slow mode) to compute absolute angle with up to 360° range and outputs via ratiometric analog voltage.
This variant is factory-configured as PPA (Pre-programmed Analog), meaning its transfer function-offset, gain, clamping levels, and linearity-is pre-calibrated and stored in EEPROM. It uses a single-die SOIC-8 package with VDD, VSS, VDIG, OUT1, and diagnostic/switch pins, omitting SPI interface pins found in BCS variants.

Use Value: 12-bit resolution enables precise 30-electrical-degree sector identification; IMC design tolerates magnet eccentricity common in low-cost motor assemblies. |
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-BCG-000-SP | Single-die SOIC-8, same Triaxis® core but standard (non-PPA) configuration requiring end-of-line calibration | Requires PTC-04 programmer and calibration fixture; suitable for designs needing custom transfer curves | Select when angular range, clamping, or linearity must be tailored per application rather than using factory defaults |
| MLX90316KGO-BCS-100-SP | Dual-die TSSOP-16 package with full hardware redundancy and SPI serial interface (14-bit output) | Supports ASIL-D functional safety architectures; provides dual independent analog outputs and fault reporting via SPI | Select for safety-critical automotive systems requiring hardware redundancy and diagnostic coverage beyond single-die capability |
Compared with MLX90316KDC-BCG-200-SP, the MLX90363KDC-BCG-000-SP offers identical form factor and sensing performance but demands post-manufacturing calibration, while the MLX90316KGO-BCS-100-SP trades SOIC-8 compactness for TSSOP-16 redundancy and digital interface-critical for ISO 26262 ASIL-D compliance.

FAQ
What output type does the MLX90316KDC-BCG-200-SP provide?
The MLX90316KDC-BCG-200-SP provides a ratiometric analog voltage output (0–100% VDD) with factory-programmed clamping, offset, and linearity-no external calibration or SPI communication required. This PPA (Pre-programmed Analog) configuration means the MLX90316KDC-BCG-200-SP delivers ready-to-use angular data immediately after power-up, simplifying system integration for analog-input MCUs.
Does the MLX90316KDC-BCG-200-SP support SPI or PWM output modes?
No-the MLX90316KDC-BCG-200-SP is configured exclusively for analog output and does not support SPI or PWM modes. Its BCG-200 option code denotes Pre-programmed Analog functionality, and the SOIC-8 pinout omits MOSI/MISO/SCLK pins. For SPI or PWM capability, select MLX90316KDC-BCS-100-SP or MLX90316KGO-BCS-100-SP instead.
What is the operating temperature range of the MLX90316KDC-BCG-200-SP?
The MLX90316KDC-BCG-200-SP is qualified for continuous operation from -40°C to +125°C (K-grade), meeting AEC-Q100 requirements for under-hood automotive applications. Its thermal angular accuracy remains within ±0.1° over this full range due to on-chip DSP compensation and factory calibration at temperature extremes.
How is the MLX90316KDC-BCG-200-SP calibrated before shipment?
The MLX90316KDC-BCG-200-SP undergoes end-of-line calibration using Melexis' PTC-04 programming unit to program its EEPROM with a complete transfer function-including offset, gain, clamping thresholds, and linearity correction coefficients. This results in a fully characterized ratiometric analog output that requires no further calibration by the customer, making the MLX90316KDC-BCG-200-SP plug-and-play for analog-sensing systems.
Can the MLX90316KDC-BCG-200-SP be used in safety-critical automotive applications?
Yes-the MLX90316KDC-BCG-200-SP includes integrated diagnostics (VDD/VSS monitoring, output saturation detection, magnetic field validity check) and meets AEC-Q100 Grade 0/1 reliability standards. While it is a single-die device and thus suited for ASIL-B applications, ASIL-D systems require dual-die redundancy-achieved with the MLX90316KGO-BCS-100-SP variant, not the MLX90316KDC-BCG-200-SP.
