Product details

Overview

MLX90374GVS-ABB-307-RX from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers dual-output SENT + programmable switch signals, operates from -40°C to +160°C, features ISO 26262 ASIL-C safety compliance, and supports stray-field immune angular/linear configurations in DMP-4 package. It enables non-contacting throttle, pedal, and steering wheel position sensing in automotive powertrain and chassis systems.

For engineers reviewing the MLX90374GVS-ABB-307-RX datasheet, pinout, applications, or equivalent options, this page provides verified functional context, DMP-4 terminal mapping, SENT/PWM timing constraints, ASIL-C diagnostic coverage details, and validated alternative options for automotive position-sensing designs.

Technical Context

The MLX90374GVS-ABB-307-RX integrates a Triaxis® Hall front end sensitive to B_x, B_y, and B_z magnetic components, an analog-to-digital signal conditioner, and a DSP for real-time angle decoding. Its DMP-4 package embeds decoupling capacitors and uses a PCB-less dual-mold construction with straight leads (STD3 2.00).

This variant implements legacy angular/linear mode (-300 option code) with SENT vAPR2016 protocol and programmable switch output. It supports configurable filtering (FIR11/FIR1111), dual diagnostics cycles (DCT_ANA = 34 ms, DCT_DIG = 20 ms), and failsafe state duration of 9.8–34.6 ms depending on revision.

Key Specifications

Parameter	Value and Actual Design Meaning
Operating Temp	-40°C to +160°C - qualified for under-hood automotive environments without external thermal derating.
Supply Voltage	4.5–5.5 V (regulated) or 6–18 V (battery) - supports dual supply modes via WARM_ACT_HIGH configuration.
Output Interface	SENT (SAE J2716 APR2016) + programmable switch - enables high-resolution serial data with CRC and fault reporting plus discrete status signaling.
Accuracy Mode	Legacy / Angular Rotary / Linear position (-300 code) - optimized for broad-angle applications without stray-field immunity enhancements.
Package	DMP-4 (PCB-less dual mold) with STD3 2.00 trim & form - surface-mountable, no PCB required, integrated 10 nF decoupling caps (C1/C4).
Safety Certification	ISO 26262 ASIL-C Safety Element out of Context - provides documented safety mechanisms for integration into ASIL-B/C systems.
Startup Time	T_stup = 6.60–6.99 ms (SENT) - time to first valid angle output; safe startup disabled (ABB revision lacks COLD_SAFE_STARTUP_EN).

Pinout & Package

DMP-4 is a PCB-less dual-mold package with 4 terminals, designed for direct soldering onto flex or rigid substrates. It integrates internal 10 nF decoupling capacitors (C1/C4) and uses straight leads with 2.00 mm pitch (STD3).

Pin/Terminal	Circuit Role	Design Meaning
1	OUT1	Primary SENT output - delivers 12-bit angle data, CRC, diagnostics, and user-defined values per SAE J2716 frame.
2	VSS	Analog/digital ground reference - must be connected to system ground; shared return path for both outputs and supply.
3	VDD	Power input - accepts 4.5–18 V; internal regulator generates 3.3 V analog rail (VDEC) and 1.85 V digital rail (VDDD).
4	OUT2	Programmable switch output - open-drain or push-pull configurable; used for status flag, error indication, or secondary control signal.

Key Features

Feature	Design Value
Triaxis® Hall Sensing	Simultaneous measurement of B_x, B_y, B_z enables robust 0–360° absolute angle or linear displacement decoding without mechanical wear.
SENT + Switch Dual Output	Combines high-fidelity serial position data with deterministic discrete signaling - eliminates need for external logic or second IC in safety-critical feedback loops.
Stray-Field Immunity Config	Legacy (-300) mode supports standard angular/linear applications where magnet placement allows predictable field geometry; not optimized for high-interference zones.
ASIL-C Safety Element	Includes watchdog timers (IWD/AWD), memory ECC, analog diagnostics, and fail-safe state - reduces integration effort for ISO 26262-compliant ECU designs.
DMP-4 Integrated Decoupling	Built-in 10 nF capacitors (C1/C4) eliminate external passive components, reduce PCB area, and improve EMC performance in compact sensor modules.

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-307-RX	ABC revision adds COLD_SAFE_STARTUP_EN, enhanced diagnostics, and full ASIL-C support documentation; ABB lacks safe startup and has reduced DCTDIG coverage.	Required for new ASIL-C designs needing certified safe startup sequence and updated safety manual; ABC is Melexis' preferred revision.	Select ABC-307-RX for all new designs requiring full ISO 26262 compliance traceability and long-term product support.
MLX90363GDC-ABB-000-TU	SOIC-8 package, single PWM output only, no SENT, no programmable switch; lower integration, no ASIL-C claim.	Suitable for cost-sensitive, non-safety-critical linear/rotary sensing where serial diagnostics are unnecessary.	Choose only if design mandates SOIC-8 footprint, single-output simplicity, and does not require ASIL-C or SENT protocol.

Compared with MLX90374GVS-ABB-307-RX, the ABC-307-RX offers verified safe startup and extended diagnostic coverage essential for ASIL-C integration, while the MLX90363GDC-ABB-000-TU trades protocol flexibility and safety certification for lower cost and simpler layout - neither is pin-compatible due to differing package (DMP-4 vs SOIC-8) and terminal count (4 vs 8).

Yes, the MLX90374GVS-ABB-307-RX supports SENT communication compliant with SAE J2716 APR2016. It delivers 12-bit angle data, CRC checksums, diagnostic flags, and user-defined fields in standard or fast (1.5 µs tick) modes, with configurable frame length and pause behavior as defined in Section 10.2 of the datasheet.

What package type and pin configuration does the MLX90374GVS-ABB-307-RX use?

The MLX90374GVS-ABB-307-RX uses the DMP-4 (Dual Mold Package) - a PCB-less 4-terminal surface-mount package with STD3 2.00 mm lead pitch and integrated 10 nF decoupling capacitors. Pinout is: 1=OUT1, 2=VSS, 3=VDD, 4=OUT2, as specified in Table 5 of the datasheet.

Is the MLX90374GVS-ABB-307-RX certified for functional safety applications?

The MLX90374GVS-ABB-307-RX is qualified as an ISO 26262 ASIL-C Safety Element out of Context (SEooC). It includes hardware-level safety mechanisms such as dual watchdogs, memory ECC, analog diagnostics, and failsafe state entry - though full ASIL-C integration requires system-level validation per the safety manual (Section 13).

What is the difference between ABB and ABC revisions of the MLX90374GVS-307-RX?

The ABB revision (used in MLX90374GVS-ABB-307-RX) is not recommended for new designs and lacks COLD_SAFE_STARTUP_EN, reduced diagnostic cycle time (DCT_DIG = 20 ms vs 17 ms in ABC), and incomplete ASIL-C documentation. The ABC revision adds verified safe startup, enhanced diagnostics, and full safety manual support - Melexis explicitly recommends ABC for all new projects.
