Product details
Overview
MLX90372GDC-ACC-100-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary/linear position sensing, operating from -40°C to +160°C, featuring SENT or PWM output, ISO26262 ASIL-C safety compliance, and AEC-Q100 qualification - deployed in automotive throttle and pedal position systems.
For engineers reviewing the MLX90372GDC-ACC-100-RE datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (SOIC-8), confirmed SENT/PWM dual-output capability, stray-field immune angular mode (-100 option code), and functional safety architecture per ISO26262 SEooC requirements.
Technical Context
The MLX90372GDC-ACC-100-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling 0–360° absolute angle decoding with on-chip DSP and analog signal conditioning. Its architecture supports programmable piecewise linear (PWL) transfer characteristics using 4–32 points and configurable SENT frame timing per SAE J2716 APR2016.
This variant uses the ACC chip revision in SOIC-8 package (DC), implements the -100 option code for Rotary Stray-field Immune – Low Field Variant, and delivers SENT output with 3 µs tick time in asynchronous acquisition mode (TangleMeas = 528–588 µs). It does not support full redundancy or DMP-4 packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments without derating. |
| Supply Voltage | 4.5 V to 5.5 V - regulated mode operation; supports battery input up to 18 V via internal PTC detection. |
| Supply Current | 9.0–12.6 mA - specified for stray-field immune applications (-100 code), enabling low-power sensor nodes. |
| Output Interface | SENT (SAE J2716 APR2016) or PWM - selectable via programming; SENT includes error codes and 48-bit ID. |
| Magnetic Sensing | Bx/By/Bz triaxial detection - enables contactless absolute position measurement with immunity to orthogonal stray fields. |
| Accuracy | ±0.3° typical angular error in -100 mode - validated for high-fidelity throttle and steering wheel position feedback. |

Pinout & Package
MLX90372GDC-ACC-100-RE is housed in an RoHS-compliant SOIC-8 package (8-pin, 150 mil width), with pins 1–8 mapped as follows:
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VDD | Supply input | Primary power rail (4.5–5.5 V); connects to external decoupling capacitor via pin 7. |
| 2 Input | Application/test interface | Internally grounded in standard use; reserved for diagnostics or NTC gateway in alternate configurations. |
| 3 Test | Application/test interface | Internally grounded; used during production test or optional user-defined functions. |
| 4 N.C. | No connection | Unbonded pad; must be tied to ground on PCB for EMC compliance. |
| 5 OUT | Digital output | Push-pull or open-drain SENT/PWM output; supports 3–18 V pull-up and short-circuit protection. |
| 6 VSS | Digital ground | Reference for digital logic and output stage; separate from analog ground (pin 8). |
| 7 VDEC | Decoupling node | Internal analog regulator output (3.2–3.4 V); requires 100 nF ceramic capacitor to VSS. |
| 8 VSS | Analog ground | Reference for Hall front end and ADC; must be star-connected to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous Bx/By/Bz measurement enables robust absolute angle decoding without mechanical cams or gears. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GDC-ACE-100-RE | Uses ACE chip revision (preferred for new designs); identical SOIC-8 package, -100 stray-field immune mode, and SENT/PWM functionality. | No functional difference in angular accuracy or EMC behavior; differs only in mask revision and lifetime support status. | Select ACE-100 for new designs requiring full product lifecycle assurance and latest wafer process. |
| MLX90371GDC-ACC-100-RE | Lacks DSP-based PWL programming and SENT protocol; outputs only analog ratiometric voltage or PWM with fixed transfer curve. | Not suitable for systems requiring diagnostic data, CRC-protected frames, or field-programmable linearity. | Choose only if cost-sensitive, low-complexity analog interface suffices and ASIL-C diagnostics are unnecessary. |
Compared with MLX90372GDC-ACC-100-RE, the ACE-100 offers extended manufacturability and identical performance, while the MLX90371 lacks SENT, programmable linearity, and functional safety mechanisms - making it unsuitable for ASIL-B/C systems requiring diagnostic message integrity.
