Product details
Overview
MLX90374GVS-ABC-107-RX from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary position sensing in stray-field-immune configurations. It delivers dual SENT + programmable switch outputs, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, and is AEC-Q100 qualified for automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90374GVS-ABC-107-RX datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 package with trim-and-form STD3 2.00 leads, angular rotary stray-field immunity (-100 option code), SENT protocol compliance (SAE J2716 APR2016), and dual-output diagnostic capability under functional safety constraints.
Technical Context
The MLX90374GVS-ABC-107-RX 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 computation. Its angular rotary stray-field immune mode (-100) uses dedicated magnetic configuration and internal compensation to reject orthogonal interference fields up to ±1 T.
It supports SENT output with 3 µs tick time (default), programmable switch functionality, and configurable diagnostics including intelligent watchdog (20 ms timeout) and absolute watchdog (20 ms timeout). The ABC revision enables safe startup (11.2–12.4 ms) and full diagnostic execution before first valid angle transmission.

| 2 | VSS | Digital/analog ground reference - Shared ground terminal; must be connected to low-impedance chassis or system ground for EMC stability. |
| 3 | VDD | Power supply input - Accepts 4.5–18 V; includes internal regulation (3.3 V) and over/under-voltage detection thresholds. |
| 4 | OUT2 | Programmable switch output - Open-drain or push-pull configurable; used for status signaling, fault indication, or auxiliary control logic. |
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 applications. |
| Stray-Field Immunity (-100) | Hardware-level rejection of orthogonal magnetic interference up to ±1 T - ensures stable angular output in proximity to motors, solenoids, or high-current traces. |
| SENT Protocol Compliance | Full SAE J2716 APR2016 implementation with 3 µs tick time, 12-bit angle resolution, and embedded CRC/ECC - reduces host MCU parsing overhead and improves data 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 |
|---|---|---|---|
| MLX90374GVS-ABC-100-RX | Same DMP-4 package and -100 stray-field immune configuration, but STD1 1.27 lead pitch (not STD3 2.00). | Designed for standard pitch connector interfaces; lacks pre-formed vertical leads for harness mounting. | Select when using legacy 1.27 mm pitch crimp connectors instead of 2.00 mm vertical-mount harness solutions. |
| MLX90375GVS-ABC-107-RX | Successor device with enhanced SENT frame flexibility, lower latency (1.4 ms typ.), and extended temperature range (up to +175°C). | Supports higher-speed control loops and next-gen powertrain platforms requiring extended thermal margin. | Choose for new designs targeting improved dynamic response or deployment in hotter zones (e.g., near turbochargers). |
Compared with MLX90374GVS-ABC-107-RX, the -100-RX variant requires different mechanical tooling due to lead pitch, while the MLX90375GVS-ABC-107-RX offers measurable latency reduction and thermal headroom-both trade-offs directly impact ECU timing budgets and packaging constraints.

FAQ
What is the primary magnetic configuration supported by MLX90374GVS-ABC-107-RX?
The MLX90374GVS-ABC-107-RX is configured for angular rotary stray-field immune operation (option code -100), meaning it is factory-programmed to reject orthogonal magnetic interference while delivering high-accuracy 0–360° absolute angle measurements. This configuration is validated for use with specific magnet geometries and air gaps defined in Melexis application notes, and the -107 suffix confirms STD3 2.00 lead form for DMP-4 mounting.
Does MLX90374GVS-ABC-107-RX support both SENT and PWM output simultaneously?
No, the MLX90374GVS-ABC-107-RX supports either dual PWM output or SENT + programmable switch output - not both simultaneously. Its output mode is permanently configured during programming at wafer test; the -107 ordering code specifies SENT + switch functionality. The datasheet confirms that SENT mode disables PWM generation and activates the enhanced serial protocol with error reporting and user-defined payload fields.
What is the significance of the "RX" packing form in MLX90374GVS-ABC-107-RX?
The "RX" suffix indicates tape-and-reel packaging with parts oriented face-down - a mechanical handling requirement for automated pick-and-place equipment compatible with DMP-4's lead geometry. Unlike standard "RE" reels, RX reels ensure consistent lead alignment during placement, reducing tombstoning risk. This packing form applies exclusively to VS (DMP-4) packages and is specified in Table 2 of the MLX90374 datasheet Revision 4.
How does the DMP-4 package of MLX90374GVS-ABC-107-RX differ from SOIC-8 in terms of electrical performance?
The DMP-4 package of MLX90374GVS-ABC-107-RX maintains identical electrical specifications to SOIC-8 variants - including supply current (9.0–12.6 mA), output drive strength, timing parameters, and magnetic sensitivity - because it uses the same die and internal circuitry. Differences are purely mechanical: DMP-4 omits the internal PCB, integrates decoupling capacitors (C1, C4 = 10 nF), and relies on external lead-frame grounding for EMC, as detailed in Section 14.2 of the datasheet.
Is MLX90374GVS-ABC-107-RX compliant with ISO26262 for ASIL-C integration?
Yes, the MLX90374GVS-ABC-107-RX is certified as a Safety Element out of Context (SEooC) for ISO26262 ASIL-C, with documented safety mechanisms including CRC-protected SENT frames, ECC for NVRAM, dual watchdog timers (IWD and AWD), and diagnostic coverage verified per ISO26262-5 Annex D. Its ABC revision implements safe startup and diagnostic sequencing required for ASIL-C system integration, as confirmed in Section 13 of the MLX90374 datasheet.
