Product details
Overview
MLX90377GVS-ADB-303-RX from Melexis is a monolithic Triaxis® Hall-effect position sensor IC for absolute rotary or linear position sensing. It delivers 12-bit resolution analog and PWM outputs, operates from -40°C to +160°C, supports programmable linear transfer characteristics (4–32 piecewise-linear points), and is qualified for automotive ASIL-B safety integrity in analog mode. It is used in throttle, pedal, and steering wheel position sensing where non-contacting, stray-field-immune measurement is required.
For engineers reviewing the MLX90377GVS-ADB-303-RX datasheet, pinout, applications, or equivalent options, key selection considerations include its DMP-4 package footprint, low-power analog/PWM output configuration (ADB-303), -40°C to +160°C operating range, SENT/PWM/SPC/analog protocol flexibility, and ISO26262 ASIL-B qualification for analog mode.
Technical Context
The MLX90377GVS-ADB-303-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling robust absolute angle or linear displacement decoding with appropriate magnet geometry. Its on-chip DSP performs real-time signal conditioning, including programmable filtering and piecewise-linearization.
This variant uses the DMP-4 package (PCB-less dual mold), implements Standard/Legacy Mode (ADB-3xx), and configures low-power analog/PWM output (suffix "0" in ADB-303). It does not support SENT or SPC protocols - those require ADB-33x or ADB-38x codes - and is not part of the dual-die TSSOP-16 redundant architecture.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVS-ADB-310-RX | Same DMP-4 package and analog/PWM output, but configured for High Speed Mode (higher update rate, ~10 mA typical current) | Preferred for dynamic applications requiring faster response (e.g., active suspension control loops) | Select ADB-310 if system demands <1 ms latency; ADB-303 is optimal for power-constrained or static-position monitoring use cases |
| MLX90371GVS-ADB-303-RX | Legacy Triaxis® generation; identical DMP-4 footprint and ADB-303 configuration, but lacks DSP-based linearization and ASIL-B certification | Suitable for cost-sensitive industrial applications where functional safety is not mandated | Choose MLX90371 only when ISO26262 compliance is unnecessary and legacy calibration workflows are retained |
Compared with MLX90377GVS-ADB-303-RX, the ADB-310 variant trades lower quiescent current for higher bandwidth, while the MLX90371 offers footprint compatibility without safety certification or advanced signal processing - making the MLX90377GVS-ADB-303-RX the balanced choice for ASIL-B-compliant automotive position sensing at minimal power.

FAQ
What output protocols does the MLX90377GVS-ADB-303-RX support?
The MLX90377GVS-ADB-303-RX supports only analog ratiometric and PWM output modes. Its ADB-303 option code explicitly configures Standard/Legacy Mode with low-power analog/PWM operation. SENT and SPC protocols require different option codes (e.g., ADB-33x or ADB-38x) and are not enabled or accessible on this specific variant.
Is the MLX90377GVS-ADB-303-RX pin-compatible with earlier Triaxis® sensors?
Yes - the MLX90377GVS-ADB-303-RX uses the DMP-4 package and maintains pin-to-pin compatibility with prior-generation Melexis Triaxis® sensors in the same form factor. Pins 1 (VSS), 2 (VDD), 3 (OUT), and 4 (VSS) retain identical functions and physical layout, enabling drop-in replacement in existing DMP-4 footprints without PCB redesign.
Does the MLX90377GVS-ADB-303-RX meet ISO26262 requirements?
Yes - the MLX90377GVS-ADB-303-RX is ISO26262 ASIL-B capable for analog output mode as a Safety Element out of Context (SEooC). This qualification covers built-in diagnostics including broken-wire detection, watchdog timers, and CRC-protected NVRAM, verified per Melexis Functional Safety Manual Rev. 003.
What is the operating temperature range of the MLX90377GVS-ADB-303-RX?
The MLX90377GVS-ADB-303-RX is rated for continuous operation from -40°C to +160°C ambient temperature. This extended range is validated per AEC-Q100 Grade 0 and supports placement in high-temperature automotive locations such as engine compartments and transmission housings.
Can the MLX90377GVS-ADB-303-RX be reprogrammed to change output mode after shipment?
No - output mode is permanently fixed by the ADB-303 option code programmed during factory test. The MLX90377GVS-ADB-303-RX cannot be reconfigured to SENT, SPC, or high-speed PWM in the field. Protocol selection must be made at order time; changing functionality requires hardware replacement with a different option code variant.
