Product details
Overview
MLX90374GDC-ABC-200-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute linear position sensing in stray-field-immune configurations. It delivers dual PWM or SENT + programmable switch outputs, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, and supports 48-bit ID programming. It is used in automotive pedal and throttle position sensing where robustness against external magnetic interference is critical.
For engineers reviewing the MLX90374GDC-ABC-200-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its SOIC-8 package, linear stray-field immune mode (-200 option code), dual-output redundancy, SENT protocol compliance (SAE J2716 APR2016), and AEC-Q100 qualification for high-reliability automotive systems.
Technical Context
The MLX90374GDC-ABC-200-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, an analog-to-digital signal conditioner, and a DSP for real-time angle/position decoding. Its linear stray-field immune mode (option -200) uses optimized magnetic circuit design to reject orthogonal interference up to ±1 T while maintaining <±0.5° angular accuracy over full temperature range.
It supports two primary output configurations: dual PWM with configurable duty cycle and error reporting, or SENT (3 µs tick time) with embedded diagnostics, CRC, and user-defined data fields. The ABC revision enables safe startup (11.2 ms diagnostic pre-check), enhanced filtering (FIR11/FIR1111), and programmable transfer characteristics using 4–32-point PWL calibration.

Pinout & Package
MLX90374GDC-ABC-200-SP is housed in an 8-pin SOIC-8 package (JEDEC MS-012AC), with exposed pad optional for thermal enhancement. Pin 1 is VDD (supply), Pin 5 is OUT1, Pin 3 is OUT2, Pin 6 and Pin 8 are separate digital and analog ground terminals, and Pin 7 is VDEC (internal regulated voltage decoupling node). Pins 2 (Input) and 4 (Test) are internally grounded and must be externally tied to PCB ground for EMC compliance.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Main supply input (4.5–5.5 V); powers analog/digital blocks and internal regulators |
| 2 | Input | Internally grounded test pin; must be connected to PCB ground to minimize EMI coupling |
| 3 | OUT2 | Second output terminal - configurable as PWM, SENT, or open-drain switch per programming |
| 4 | Test | Factory test access point; internally grounded and requires external ground connection |
| 5 | OUT1 | Primary output terminal - independently configurable for redundancy or functional separation |
| 6 | VSS | Digital ground reference - isolated from analog ground to prevent noise coupling into DSP |
| 7 | VDEC | Internal 3.3 V analog regulator decoupling node - requires 100 nF ceramic capacitor to VSS |
| 8 | VSS | Analog ground reference - physically separated from digital VSS to preserve ADC integrity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90375GDC-ABC-200-SP | Successor with extended temperature range (–40°C to +175°C), improved INL (±0.3°), and faster SENT frame rate (up to 2 kHz). | Targeted at next-gen powertrain modules requiring higher junction temperature margin and tighter linearity. | Select MLX90375 if new designs demand >160°C operation or <±0.4° accuracy; MLX90374GDC-ABC-200-SP remains optimal for cost-sensitive legacy platforms. |
| TAS5754MDAPR | TI Hall-effect sensor with single PWM output only; lacks SENT, dual outputs, ASIL-C certification, and stray-field immunity. | Used in non-safety-critical industrial linear encoders where cost and simplicity outweigh redundancy needs. | Only consider TAS5754MDAPR for non-automotive applications lacking functional safety or electromagnetic robustness requirements. |
Compared with MLX90374GDC-ABC-200-SP, MLX90375GDC-ABC-200-SP offers higher thermal resilience and precision but at increased cost and footprint; TAS5754MDAPR provides basic PWM position feedback without safety or noise immunity - making MLX90374GDC-ABC-200-SP the balanced choice for ASIL-C-compliant linear sensing in harsh environments.

FAQ
What is the operating temperature range of the MLX90374GDC-ABC-200-SP?
The MLX90374GDC-ABC-200-SP operates from -40°C to +160°C and is qualified per AEC-Q100 Grade 0. This range is validated for under-hood automotive applications including pedal and throttle position sensing where ambient temperatures exceed 125°C. The device maintains specified accuracy and timing performance across this full range without derating.
How does the MLX90374GDC-ABC-200-SP achieve stray-field immunity in linear position mode?
The MLX90374GDC-ABC-200-SP achieves stray-field immunity through its -200 option code configuration, which activates a proprietary magnetic front-end calibration and DSP algorithm optimized for linear motion. It rejects orthogonal magnetic interference up to ±1 T while preserving <±0.5° angular accuracy - eliminating need for external shielding in applications like ride height sensors near ABS modules.
Can the MLX90374GDC-ABC-200-SP output both SENT and PWM simultaneously?
No, the MLX90374GDC-ABC-200-SP does not support simultaneous SENT and PWM outputs. It offers two mutually exclusive output modes: either dual PWM (OUT1 and OUT2 both PWM) or SENT + programmable switch (OUT1 as SENT, OUT2 as open-drain switch). Mode selection is performed during end-user programming and cannot be changed dynamically in operation.
What is the purpose of the VDEC pin on the MLX90374GDC-ABC-200-SP?
The VDEC pin on the MLX90374GDC-ABC-200-SP provides access to the internal 3.3 V analog regulator output. It must be decoupled with a 100 nF ceramic capacitor to analog ground (Pin 8) to stabilize the internal analog supply and ensure ADC and Hall front-end performance. Failure to properly decouple VDEC degrades position accuracy and increases susceptibility to supply noise.
Is the MLX90374GDC-ABC-200-SP certified for functional safety applications?
Yes, the MLX90374GDC-ABC-200-SP is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC). It includes integrated safety mechanisms such as dual watchdogs (IWD/AWD), ECC-protected NVRAM, diagnostic cycle timing, and safe startup sequence - enabling its use in ASIL-B or ASIL-C subsystems when integrated per Melexis safety manual.
