Product details
Overview
MLX90372GVS-ACE-300-RX from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers SENT or PWM output, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, and uses a PCB-less DMP-4 package with pinout-A configuration for automotive pedal, throttle, and steering wheel position sensing.
For engineers reviewing the MLX90372GVS-ACE-300-RX datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 package footprint, SENT 3µs mode support, -300 legacy angular/linear mode, stray-field robustness, and AEC-Q100 qualification for high-reliability automotive systems.
Technical Context
The MLX90372GVS-ACE-300-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling absolute angle decoding from 0° to 360° or linear displacement without contact. Its on-chip DSP performs real-time signal conditioning, piecewise linear (PWL) transfer function mapping (up to 32 points), and SENT frame encoding per SAE J2716 APR2016.
This variant uses the ACE chip revision in DMP-4 package (pinout-A), supports programmable measurement range and linear transfer characteristic, and implements dual watchdogs (IWD/AWD) with 20 ms timeout. It operates in continuous asynchronous acquisition mode with 588 µs typical angle measurement period and built-in decoupling capacitors per section 15.3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - Enables under-hood and transmission-mounted deployment without external thermal derating. |
| Supply Voltage | 4.5 V to 5.5 V - Compatible with regulated 5 V automotive domains; supports battery operation up to 18 V via internal PTC detection. |
| Supply Current | 8.0–10.5 mA - Optimized for low-power legacy (-300) mode; enables extended ECU power budget allocation. |
| Output Protocol | SENT (3 µs tick) or PWM - Configurable via programming; SENT provides 48-bit ID, error codes, and user-defined data per frame. |
| Magnetic Sensing | Bx/By/Bz triaxial Hall - Enables single-IC absolute position decoding from rotating or translating magnets without mechanical coupling. |

Pinout & Package
DMP-4 package (PCB-less dual mold, STD1 1.27 mm pitch, RoHS-compliant) with pinout-A configuration - compact 4-pin surface-mount footprint optimized for direct magnet coupling and space-constrained sensor assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Analog/digital ground reference; must be connected to PCB ground plane for EMC stability and noise immunity. |
| 2 | VDD | Main supply input (4.5–5.5 V); internally regulated to 3.3 V analog rail and 1.85 V digital rail. |
| 3 | OUT | Configurable SENT/PWM output; push-pull capable; supports open-drain mode with external pull-up to 5–18 V. |
| 4 | VSS | Second ground terminal; improves current return path symmetry and reduces ground bounce in high-noise environments. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous Bx/By/Bz measurement enables true 3D magnetic field decoding - eliminates need for external concentrators or multi-die solutions in rotary/linear topologies. |
| Programmable PWL Transfer | Up to 32-point piecewise linear calibration allows precise compensation of mechanical nonlinearity (e.g., cam profiles, lever arms) without host MCU intervention. |
| SENT Secure Sensor Format | Embedded 48-bit ID, CRC, diagnostics, and user payload in each frame - enables traceability, fault isolation, and OEM-specific parameterization in production ECUs. |
| Stray-Field Immunity | Validated performance in >100 mT stray fields - critical for placement near motors, solenoids, or high-current traces without shielding. |
| Dual Watchdog Architecture | Independent IWD (20 ms) and AWD (20 ms) timers with fail-safe state activation - ensures deterministic response to software lockup or sensor freeze. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-ACE-300-RX | Single-die version with identical DMP-4 pinout-A, same SENT/PWM capability, but lacks ASIL-C certification and dual watchdog architecture. | Targeted at non-safety-critical industrial linear/rotary sensing; not qualified for ASIL-B/C automotive systems. | Select when functional safety compliance is not required and cost optimization is prioritized over diagnostic coverage. |
| TLV493DW2B6HXTSA1 | Infineon 3D Hall sensor with I²C interface only; no SENT/PWM output; no programmable PWL; no ASIL-C or AEC-Q100 Grade 0 rating. | Designed for consumer/industrial proximity and orientation sensing; unsuitable for automotive position feedback loops requiring deterministic timing and diagnostics. | Consider only for non-automotive, low-cost, I²C-based designs where SENT protocol and safety certification are unnecessary. |
Compared with MLX90372GVS-ACE-300-RX, the MLX90371 alternative omits ASIL-C safety mechanisms and diagnostic depth, while the TLV493D lacks SENT output, automotive qualification, and programmable transfer functions - making MLX90372GVS-ACE-300-RX the sole choice for safety-critical, SENT-based, field-robust position sensing in DMP-4 form factor.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACE-300-RX?
The MLX90372GVS-ACE-300-RX uses the DMP-4 (Dual Mould Package) with pinout-A configuration: Pin 1 = VSS, Pin 2 = VDD, Pin 3 = OUT, Pin 4 = VSS. This PCB-less 4-pin package has 1.27 mm pitch and integrates decoupling capacitors, as confirmed in datasheet section 15.3 and ordering code VS/ACE-300/RX.
Does MLX90372GVS-ACE-300-RX support SENT and PWM output simultaneously?
No, MLX90372GVS-ACE-300-RX supports either SENT or PWM output - selected during programming via the Output Mode parameter (section 13.1). The device cannot transmit both protocols concurrently; SENT is default for automotive applications, while PWM serves legacy or cost-sensitive designs requiring analog-compatible timing.
What is the meaning of "ACE-300" in MLX90372GVS-ACE-300-RX?
In MLX90372GVS-ACE-300-RX, "ACE" denotes the preferred chip revision (standard production version), and "300" specifies the legacy angular/linear position mode - supporting both rotary (0–360°) and linear displacement applications without stray-field immunity enhancements. This matches Table 2 and section 8.4 of the datasheet.
Is MLX90372GVS-ACE-300-RX qualified for automotive use?
Yes, MLX90372GVS-ACE-300-RX is AEC-Q100 Grade 0 qualified (−40°C to +160°C) and certified to ISO26262 ASIL-C as a Safety Element out of Context (SEooC), making it suitable for safety-critical automotive applications including throttle, pedal, and steering position sensing per OEM functional safety requirements.
What diagnostic capabilities does MLX90372GVS-ACE-300-RX provide?
MLX90372GVS-ACE-300-RX includes dual watchdogs (IWD and AWD, both 20 ms timeout), SENT frame CRC and error-code reporting, analog/digital diagnostics cycle times (34 ms and 20 ms), and configurable fail-safe state activation. These are detailed in sections 7.1, 11.1, and 14.2 of the datasheet and support ASIL-C integration without external supervision.
