It provides 12-bit resolution, 10-bit thermal accuracy, programmable linear transfer characteristic, and operates across –40 °C to +125 °C in SOIC-8 package. Used in throttle, steering wheel, and pedal position sensing where non-contact robustness is critical.
For engineers reviewing the MLX90367KDC-ABU-000-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options for automotive and industrial position-sensing designs.
Technical Context
The MLX90367KDC-ABU-000-RE integrates on-chip analog signal processing (ASP) and digital signal processing (DSP) to compute absolute angular or linear position from orthogonal and parallel magnetic flux components. Its Triaxis® architecture enables full 360° rotary decoding or stroke-length linear sensing using a single moving magnet and passive magnetic circuit.
It implements SENT protocol with Throttle Sensor Format or Secure Sensor Format frames, supporting diagnostic reporting via fast channel and enhanced serial messages via slow channel. The device features factory-trimmed sensitivity mismatch compensation (SMISM), programmable discontinuity point (DP), and configurable FIR filter (FILTER = 0/1/2) to optimize latency–noise trade-offs.

FAQ
What is the operating temperature range of the MLX90367KDC-ABU-000-RE?
The MLX90367KDC-ABU-000-RE is rated for –40 °C to +125 °C (K-grade), validated per AEC-Q100 stress testing. This range covers under-hood locations such as throttle bodies and brake master cylinders. Thermal offset correction and sensitivity drift compensation are factory-trimmed to maintain angular accuracy within ±0.3° across the full span. The "K" suffix explicitly denotes this temperature grade.
Does the MLX90367KDC-ABU-000-RE support SENT protocol version compatibility?
Yes, the MLX90367KDC-ABU-000-RE implements SENT per SAE J2716-2010 (Revision 3), supporting both Throttle Sensor Format and Secure Sensor Format frames. It delivers 12-bit position data in the fast channel with diagnostic bits, and user-defined values in the slow channel. Frame period is fixed at 882 μs; no support for SENT v4.0 dynamic frame length or CRC enhancements found in newer variants like MLX90377.
Can the MLX90367KDC-ABU-000-RE be programmed in-system for custom transfer characteristics?
Yes, the MLX90367KDC-ABU-000-RE supports end-user programming of its linear transfer function via 3-point interpolation (LNR parameters). Using Melexis' PTC GUI and compatible programmer, users can write AX/AY/AS, BX/BY/BS, and CX/CY/CS coordinates to EEPROM to correct for mechanical tolerances or magnetic field distortion. Programming requires SENT communication and does not require reflow or physical access to the die.
What is the meaning of "ABU-000" in the MLX90367KDC-ABU-000-RE part number?
"ABU-000" is the Option Code indicating a specific die revision and feature set: "AB" denotes an early production variant (not recommended for new designs per Melexis' ordering table), "U" specifies 3-point linearization capability (AxU), and "000" confirms standard configuration with no customer-specific firmware or calibration. This differs from ACU-000 (standard production version) and ACX-000 (with thermal offset correction enabled).
How does the MLX90367KDC-ABU-000-RE handle electromagnetic interference in automotive environments?
The MLX90367KDC-ABU-000-RE achieves robust EMC performance through SENT's edge-based encoding (immune to amplitude noise), integrated IMC® that enhances signal-to-noise ratio, and strict pinout recommendations - unused test pins (2, 3, 6) must be tied to VSS per datasheet Section 4. It meets ISO 11452-2/4 for radiated immunity and ISO 7637-2 for transient burst suppression without external filtering, provided layout follows Melexis' recommended trace width, ground plane, and decoupling guidelines.
