Product details
Overview
MLX90377GVE-ADB-300-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SMP-3 package, delivering 12-bit ratiometric analog or PWM output with programmable linear transfer characteristic (4/8/16/32-point PWL), -40°C to 160°C operating range, and ASIL-B functional safety compliance for analog mode. It decodes absolute rotary or linear magnet position via Bx/By/Bz field sensing and is used in throttle, pedal, and ride height sensing.
For engineers reviewing the MLX90377GVE-ADB-300-RE datasheet, pinout, applications, or equivalent options, key selection criteria include SMP-3 package compatibility, low-power analog/PWM output configuration, stray-field immunity mode (Standard/Legacy), and ASIL-B safety capability for automotive position feedback systems.
Technical Context
The MLX90377GVE-ADB-300-RE integrates a Triaxis® Hall front end, 12-bit ADC, DSP-based signal conditioner, and analog/PWM output stage in a single-die SMP-3 package. Its architecture supports real-time magnetic vector decomposition (Bx, By, Bz) and on-chip piecewise-linear interpolation for absolute angle or displacement decoding without external microcontroller intervention.
This variant operates in Standard/Legacy Mode with low-power analog/PWM output, uses a 12 MHz main clock (±2.5% thermal drift), and implements passive broken-wire diagnostics on VDD/VSS. It does not support SENT or SPC protocols - those require ADB-330/380 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Mode | Analog ratiometric or PWM only; no SENT/SPC - fixed at factory per ADB-300 option code. |
| Resolution | 12-bit effective resolution for position output, enabling ≤0.1° angular or ≤0.025 mm linear accuracy in calibrated systems. |
| Operating Temp | -40°C to +160°C junction temperature - validated for under-hood automotive environments without derating. |
| Supply Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery); startup threshold at 4.1 V typical ensures robust cold-cranking operation. |
| Supply Current | 8–11.5 mA typical in Legacy Mode - optimized for low-power ECU subsystems with continuous position monitoring. |
| Safety Rating | ISO 26262 ASIL-B capable for analog output mode as Safety Element out of Context (SEooC), with diagnostic coverage for open-circuit and short-circuit faults. |
| Magnetic Input | Sensitive to full 3-axis flux density (Bx, By, Bz); supports absolute 0–360° rotary or linear stroke sensing with custom magnetic circuit design. |
Pinout & Package
SMP-3 is a PCB-less single-mold package with three solderable terminals and two test pads (INPUT/TEST), designed for direct magnet-side mounting in space-constrained automotive sensors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Supply input | Accepts 4.5–18 V; internal reverse-polarity and overvoltage protection up to -14 V / +28 V. |
| 2 (OUT) | Output driver | Push-pull analog ratiometric (0.5–99% VDD) or PWM (5–95% duty cycle); supports 5–100 kΩ load. |
| 3 (VSS) | Ground reference | Primary return path; enables broken-wire detection when pulled low or high via external resistor network. |
| a (INPUT) | Factory test interface | Not user-accessible in final application; used during calibration and programming at Melexis. |
| b (TEST) | Factory test interface | Reserved for production testing; must be left floating or grounded per layout guidelines for EMC stability. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Enables absolute position measurement from a single magnet using orthogonal Bx/By/Bz field components - eliminates need for dual-Hall or resolver solutions. |
| Programmable PWL Transfer | Supports 4-, 8-, 16-, or 32-point piecewise-linear calibration curves stored in NVRAM, allowing precise compensation of mechanical nonlinearity without host MCU computation. |
| Stray-Field Immunity Mode | This ADB-300 variant uses Standard/Legacy Mode - optimized for cost-sensitive applications where external magnetic shielding is implemented separately. |
| On-Chip Diagnostics | Includes passive broken-wire detection on VDD/VSS and active output short-circuit monitoring - meets ASIL-B fault detection timing requirements. |
| Low-Power Operation | 8–11.5 mA supply current at 5 V enables integration into always-on vehicle subsystems (e.g., brake pedal sensing) without thermal or power budget impact. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVE-ADB-310-RE | Same SMP-3 package and Standard/Legacy Mode, but configured for High Speed Mode (12 MHz clock, faster update rate). | Required where >1 kHz sampling or lower latency (<2 ms) is needed - e.g., high-bandwidth EPS feedback loops. | Select ADB-310 if system demands higher dynamic response; ADB-300 remains optimal for cost-sensitive, low-update-rate applications like ride height. |
| MLX90377GDC-ADB-300-RE | Identical functionality and firmware, but in SOIC-8 package (8-pin, surface-mount) instead of SMP-3 (3-terminal, PCB-less). | Used where board-level assembly is preferred over direct magnet-side mounting; requires external decoupling and layout for EMC. | Choose SOIC-8 version when integrating into conventional PCB-based modules; SMP-3 is superior for compact, sealed sensor housings. |
Compared with MLX90377GVE-ADB-310-RE, the MLX90377GVE-ADB-300-RE trades update speed for lower quiescent current and simplified timing constraints; compared with MLX90377GDC-ADB-300-RE, it replaces board-level assembly with direct-mount ruggedization - making it ideal for OEM-specified compact position sensors.

FAQ
What output protocols does the MLX90377GVE-ADB-300-RE support?
The MLX90377GVE-ADB-300-RE supports only analog ratiometric and PWM output modes - selected at factory via the ADB-300 option code. It does not support SENT or SPC protocols; those require ADB-330 or ADB-380 variants. Output mode cannot be changed post-manufacture.
Is the MLX90377GVE-ADB-300-RE pin-compatible with other MLX90377 package variants?
No - the MLX90377GVE-ADB-300-RE uses the SMP-3 package with three solder terminals (VDD, OUT, VSS) and two test pads, while SOIC-8 has eight pins and TSSOP-16 has sixteen. Pin mapping, footprint, and mounting method differ fundamentally; board redesign is required for cross-package substitution.
Does the MLX90377GVE-ADB-300-RE meet ISO 26262 functional safety requirements?
Yes - the MLX90377GVE-ADB-300-RE is certified ASIL-B capable for analog output mode as a Safety Element out of Context (SEooC), with documented fault detection mechanisms for open-circuit, short-circuit, and broken-wire conditions on VDD/VSS lines per ISO 26262 Part 5 Annex D.
What is the magnetic field range supported by the MLX90377GVE-ADB-300-RE?
The MLX90377GVE-ADB-300-RE operates within ±1 T magnetic flux density (Bx, By, Bz) and is specified for Standard/Legacy Mode - meaning it relies on external magnetic circuit design (e.g., diametrically magnetized ring or bar magnets) rather than built-in stray-field immunity. Full accuracy requires proper magnet placement per Melexis Application Note AN-102.
Can the transfer characteristic of the MLX90377GVE-ADB-300-RE be customized after purchase?
Yes - the MLX90377GVE-ADB-300-RE includes 128 bytes of user-programmable NVRAM storing up to 32-point piecewise-linear (PWL) coefficients. Calibration data can be written via Melexis' PTM software and PTC interface (using VDD voltage ramp), enabling field-specific linearization without hardware change.
