Product details
Overview
MLX90374GDC-ABB-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 output, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, AEC-Q100 qualification, and supports programmable linear transfer characteristics with up to 32-point piecewise linear (PWL) calibration - deployed in automotive pedal and throttle position sensing systems.
For engineers reviewing the MLX90374GDC-ABB-200-SP datasheet, pinout, applications, or equivalent options, key selection considerations include its SOIC-8 package, dual-output redundancy mode, linear stray-field immunity (-200 option code), SENT/PWM protocol flexibility, and functional safety architecture per ISO26262 SEooC.
Technical Context
The MLX90374GDC-ABB-200-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, an analog-to-digital signal conditioner, and a DSP for real-time angle/position decoding. Its architecture enables absolute linear displacement measurement without mechanical contact using external magnets and optimized magnetic circuits.
This variant implements the -200 option code: linear position stray-field immune configuration with factory-programmed transfer function, dual PWM output mode (3 µs SENT-compatible timing), and SOIC-8 packaging. It uses internal 24 MHz main clock (±5% over temp/lifetime) and supports configurable diagnostics including intelligent watchdog (20 ms timeout) and fail-safe state activation within 11.0–34.6 ms after digital fault detection.

Pinout & Package
MLX90374GDC-ABB-200-SP is housed in an 8-pin SOIC-8 package (JEDEC MS-012AC) with exposed pad not connected internally. Pin 1 is VDD (supply), Pin 2 (Input) and Pin 4 (Test) are internally grounded and must be tied to PCB ground for EMC compliance, Pin 3 and Pin 5 are dedicated output drivers (OUT2 and OUT1), Pins 6 and 8 are digital/analog grounds (VSS), and Pin 7 is VDEC (internal regulated voltage decoupling node requiring 100 nF ceramic capacitor to ground).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Power supply input | Accepts 4.5–5.5 V regulated supply; internal LDO generates 3.3 V analog rail (VDEC) |
| 2 (Input) | Reserved test pin | Internally grounded; connect externally to PCB ground for EMI suppression |
| 3 (OUT2) | Secondary digital output | PWM push-pull driver (max 15 mA sink/source); configurable as redundant or independent channel |
| 4 (Test) | Reserved test pin | Internally grounded; connect externally to PCB ground for EMI suppression |
| 5 (OUT1) | Primary digital output | PWM push-pull driver (max 15 mA sink/source); primary channel for position reporting |
| 6 (VSS) | Digital ground reference | Return path for digital logic and output drivers; separate from analog ground |
| 7 (VDEC) | Analog voltage decoupling | Internal 3.3 V analog supply node; requires 100 nF ceramic capacitor to Pin 8 (VSSA) |
| 8 (VSS) | Analog ground reference | Return path for Hall sensor front-end and ADC; must be star-grounded near VDEC |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90374GDC-ABC-200-RE | ABC revision replaces ABB; adds enhanced diagnostics, safe startup sequence, and extended SENT protocol support | Same linear stray-field immune function but with improved ASIL-C diagnostic coverage and reduced startup latency uncertainty | Select ABC-200 for new designs requiring full ISO26262 tool qualification support and long-term lifecycle assurance |
| TLV493DW2B6H1XUMA1 | Infineon 3D Hall sensor with I²C interface; no integrated DSP or PWM output; requires external MCU for position calculation | Lacks on-chip signal processing and dual-output redundancy; suited for cost-sensitive non-safety systems | Choose only if system already includes capable host MCU and does not require ASIL-C compliance or PWM-native interface |
Compared with MLX90374GDC-ABB-200-SP, the ABC-200 offers verified safe startup and expanded diagnostic coverage for higher-integrity systems, while TLV493DW2B6H1XUMA1 shifts signal processing burden to host firmware and omits functional safety mechanisms - making it unsuitable for ASIL-B/C deployment without extensive validation effort.

FAQ
What is the operating temperature range of the MLX90374GDC-ABB-200-SP?
The MLX90374GDC-ABB-200-SP is rated for continuous operation from -40°C to +160°C ambient temperature and qualified to AEC-Q100 Grade 0 standards. This range supports under-hood placement in modern ICE, hybrid, and EV powertrain modules where thermal stress exceeds conventional commercial-grade IC limits. The device maintains specified accuracy and timing performance across this full range.
Does the MLX90374GDC-ABB-200-SP support SENT output?
No - the MLX90374GDC-ABB-200-SP is configured exclusively for dual PWM output per its ABB-200 option code. While the underlying MLX90374 silicon supports SENT, this specific variant disables SENT functionality and enables two independent PWM channels. SENT capability requires ABC-200 or ABC-300 variants with appropriate programming.
What does the "-200" in MLX90374GDC-ABB-200-SP signify?
The "-200" suffix denotes the linear position stray-field immune magnetic configuration. It specifies factory-programmed calibration for linear displacement measurement with enhanced rejection of orthogonal magnetic interference up to ±1 T - distinct from "-100" (rotary stray-field immune) and "-300" (legacy rotary/linear) modes. This setting is fixed at wafer sort and cannot be reprogrammed in the field.
Is the MLX90374GDC-ABB-200-SP pin-compatible with other MLX90374 variants in SOIC-8?
Yes - all MLX90374 variants in SOIC-8 package (DC suffix), including MLX90374GDC-ABB-200-SP, share identical pinout, footprint, and electrical interface. However, differences in internal configuration (e.g., ABB vs ABC revision, -200 vs -300 option) affect functional behavior, diagnostics, and startup timing - requiring matching firmware and layout validation.
What safety certifications apply to the MLX90374GDC-ABB-200-SP?
The MLX90374GDC-ABB-200-SP complies with ISO26262 ASIL-C as a Safety Element out of Context (SEooC) and is AEC-Q100 Grade 0 qualified. It incorporates hardware-level safety mechanisms including dual watchdog timers (IWD/ASD), memory ECC, and diagnostic cycle monitoring - documented in Melexis' Functional Safety Manual (FSM-MLX90374). Full system-level ASIL decomposition remains the integrator's responsibility.
