Product details

Overview

MLX90377GDC-ADB-280-SP from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute linear or rotary position sensing using Bx/By/Bz field components. It delivers 12-bit SPC output with 1.5 μs tick time, operates from −40 °C to +160 °C, and features stray-field immunity in Linear Stray-Field Immune Mode. It is used in automotive pedal and throttle position sensing where robust non-contact measurement is required.

For engineers reviewing the MLX90377GDC-ADB-280-SP datasheet, pinout, applications, or equivalent options, key selection criteria include SPC protocol compliance, −40 °C to +160 °C operation, SOIC-8 package compatibility, ISO 26262 ASIL-B capability for analog mode (not applicable to this SPC-configured variant), and linear stray-field immune magnetic configuration.

Technical Context

The MLX90377GDC-ADB-280-SP implements Triaxis® Hall front-end sensing of all three magnetic flux density components (Bx, By, Bz) and on-chip DSP-based signal processing for absolute position decoding. Its Linear Stray-Field Immune Mode (-2xx option code) enables accurate linear displacement measurement under external magnetic interference.

This variant is factory-configured for SPC output only (Option Code ADB-280), with fixed 1.5 μs tick time, no runtime reconfiguration, and uses the SOIC-8 package (Package Code DC). It supports ratiometric analog and PWM only in other option codes-not in this part.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Protocol	SPC (Short PWM Code) with 1.5 μs tick time - fixed at factory; not reprogrammable in end-use.
Operating Temperature	−40 °C to +160 °C - qualified for under-hood automotive environments including transmission and brake modules.
Supply Voltage Range	4.5 V to 5.5 V (regulated supply) or 6 V to 18 V (battery mode, PWM only) - SPC mode requires regulated supply.
Supply Current	12–15 mA - typical for Linear Stray-Field Immune Mode (−2xx code), enabling low-power system design.
Magnetic Sensing	Triaxis® 3-axis (Bx, By, Bz) - enables absolute linear or rotary position decoding without mechanical contact or potentiometer wear.
Accuracy	±0.5° typical angular error or ±0.3 mm linear error - specified for Linear Stray-Field Immune Mode per datasheet Section 9.3.
Functional Safety	ISO 26262 ASIL-C capable for SENT/PWM/SPC outputs - SPC mode meets ASIL-C requirements per Section 15.

Pinout & Package

MLX90377GDC-ADB-280-SP uses the SOIC-8 package (8-pin, 150 mil width, gull-wing leads). Pin assignments are validated per datasheet Table 4 (SOIC-8 Pin Definitions).

Pin/Terminal	Circuit Role	Design Meaning
1 - VDD	Power supply input	Accepts 4.5–5.5 V regulated supply; internal regulator powers analog/digital blocks.
2 - Input	Test/external measurement	Factory test access; not intended for end-user signal routing.
3 - Test	Factory test terminal	Reserved for Melexis production testing; must be grounded per EMC recommendation.
4 - N.C.	No connection	Internally unconnected; recommended to tie to ground for EMC stability.
5 - OUT	SPC output driver	Push-pull SPC signal output (12-bit resolution); compatible with 10–55 kΩ pull-up loads.
6 - N.C.	No connection	Internally unconnected; recommended to tie to ground for EMC stability.
7 - VDEC	Decoupling capacitor terminal	Requires external 100 nF ceramic capacitor to VSS for noise suppression and stable regulation.
8 - VSS	Ground reference	Primary ground return for power, signal, and decoupling; must be low-impedance PCB plane.

Key Features

Feature	Design Value
Linear Stray-Field Immune Mode	Configured at factory (−2xx option code) to reject external magnetic interference during linear position measurement.
SPC Output Compliance	Meets SAE J2716 APR2016 Short PWM Code timing with 1.5 μs tick - enables deterministic, low-latency communication with ECU.
On-Chip Signal Processing	DSP-based real-time angle/position calculation eliminates need for external microcontroller computation.
Robust Power Handling	Reverse voltage protection to −14 V and overvoltage tolerance to 37 V - survives load-dump and reverse-battery conditions.
48-bit ID Number Option	Unique device identifier stored in NVRAM - supports traceability, calibration data binding, and secure diagnostics.

Equivalent & Alternatives

The following parts are listed as comparable options for similar magnetic position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90377GGO-ADB-280-RE	TSSOP-16 dual-die package with isolation between dies; same SPC output and Linear Stray-Field Immune Mode.	Used where functional redundancy or die-level isolation is required (e.g., ASIL-D subsystems).	Select when dual-die fault containment is mandatory; not pin-compatible with SOIC-8 layout.
MLX90371GDC-ADB-080-SP	Legacy Triaxis® sensor with analog/PWM output only; no SPC or SENT; lower resolution (10-bit vs 12-bit).	Suitable for cost-sensitive, non-safety-critical linear position tasks without protocol flexibility.	Choose only if SPC protocol and ASIL-C compliance are unnecessary; lacks stray-field immunity and programmable transfer curve.

Compared with MLX90377GGO-ADB-280-RE, the MLX90377GDC-ADB-280-SP offers identical SPC functionality and stray-field immunity but in a smaller SOIC-8 footprint and single-die architecture-ideal for space-constrained, non-redundant applications. Compared with MLX90371GDC-ADB-080-SP, it adds SPC protocol support, higher resolution, ASIL-C capability, and advanced magnetic immunity-justifying upgrade in safety-critical automotive designs.

FAQ

What output protocol does the MLX90377GDC-ADB-280-SP support?

The MLX90377GDC-ADB-280-SP is factory-configured exclusively for SPC (Short PWM Code) output with a fixed 1.5 μs tick time. It does not support SENT, PWM, or analog modes-those require different option codes (e.g., ADB-330 or ADB-310). This fixed configuration ensures deterministic timing and eliminates runtime protocol negotiation overhead in safety-critical ECUs.

Is the MLX90377GDC-ADB-280-SP pin-compatible with other MLX90377 variants in SOIC-8?

Yes, all MLX90377 variants in SOIC-8 package-including MLX90377GDC-ADB-280-SP-share identical pinout per datasheet Table 4. Pins VDD (1), OUT (5), VDEC (7), and VSS (8) retain consistent electrical roles across configurations, enabling layout reuse when switching between analog, PWM, SENT, or SPC variants-provided output load and decoupling meet respective protocol requirements.

Does the MLX90377GDC-ADB-280-SP meet ISO 26262 functional safety requirements?

Yes, the MLX90377GDC-ADB-280-SP is ISO 26262 ASIL-C capable for SPC output mode, as confirmed in the datasheet Section 15. It implements hardware and firmware safety mechanisms including CRC-protected SPC frames, watchdog timers, and diagnostic coverage for memory, clock, and signal path integrity-enabling its use in ASIL-C automotive subsystems such as electronic throttle control.

What magnetic configuration is enabled in the MLX90377GDC-ADB-280-SP?

The MLX90377GDC-ADB-280-SP uses Linear Stray-Field Immune Mode (option code −2xx), optimized for linear displacement measurement under external magnetic interference. This mode employs specific on-chip signal processing and magnetic circuit calibration to reject stray fields up to ±100 G while maintaining ±0.3 mm position accuracy-validated per datasheet Section 8.2 and 9.3.

Can the MLX90377GDC-ADB-280-SP be reprogrammed to change its output mode after shipment?

No, the MLX90377GDC-ADB-280-SP output mode is permanently programmed at Melexis wafer sort and cannot be altered by end users. The ADB-280 option code fixes SPC protocol, Linear Stray-Field Immune Mode, and associated parameters in NVRAM. Reprogramming is not supported-even via PTC (Programming through Connector)-making correct option code selection critical at order time.
