Product details
Overview
MLX90377GVS-ADB-300-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC designed for absolute rotary or linear position sensing in harsh automotive environments. It delivers 12-bit ratiometric analog or PWM output, operates from -40°C to 160°C, supports low-power mode, and features stray-field immunity in Standard/Legacy configuration for pedal and throttle position sensing.
For engineers reviewing the MLX90377GVS-ADB-300-SP datasheet, pinout, applications, or equivalent options, key selection criteria include DMP-4 package compatibility, analog/PWM dual-mode programmability, ISO26262 ASIL-B capability for analog output, and operation under 4.5–18 V supply with integrated reverse-polarity protection.
Technical Context
The MLX90377GVS-ADB-300-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling robust absolute angle or linear displacement decoding without mechanical contact. Its on-chip DSP performs real-time signal conditioning, including 4- or 8-point piecewise-linear transfer function programming and configurable filtering.
This variant uses the DMP-4 package (PCB-less dual mold), implements Standard/Legacy Mode with analog/PWM output and low-power operation, and provides SENT/SPC protocol support via factory-programmed option code ADB-300 - not user-reprogrammable in-system. It meets ISO26262 ASIL-B for analog output and includes built-in decoupling capacitance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVS-ADB-310-SP | Same DMP-4 package and Standard/Legacy Mode, but configured for High Speed Mode (12 mA typical supply current vs. 8–9 mA) | Higher update rate and lower latency suitable for dynamic EPS or active suspension, not required for static pedal sensing | Select ADB-310 only when system demands faster response; ADB-300 remains optimal for cost- and power-sensitive throttle/pedal use cases |
| MLX90371GVS-ADB-300-SP | Legacy Triaxis® generation; 10-bit resolution, no SPC/SENT support, lower temperature rating (-40°C to +150°C), same DMP-4 pinout | Limited to legacy ECUs requiring backward-compatible analog/PWM interface without advanced diagnostics or ASIL-B certification | Choose MLX90371 only for brownfield designs where qualification time or tooling changes must be avoided; MLX90377GVS-ADB-300-SP offers superior accuracy and safety compliance |
Compared with MLX90377GVS-ADB-310-SP, the MLX90377GVS-ADB-300-SP reduces quiescent current by ~25% while maintaining identical pinout and calibration flexibility; versus MLX90371GVS-ADB-300-SP, it adds 2-bit resolution, extended temperature margin (+10°C), and ISO26262 ASIL-B evidence for analog output - directly enabling next-gen powertrain safety architectures.

FAQ
What output protocols does the MLX90377GVS-ADB-300-SP support?
The MLX90377GVS-ADB-300-SP is factory-programmed for Standard/Legacy Mode with analog ratiometric (0–VDD) and PWM output only. SENT and SPC modes require different option codes (e.g., ADB-330 or ADB-380) and are not reconfigurable post-manufacture. The MLX90377GVS-ADB-300-SP delivers 12-bit resolution in both analog and PWM formats, with output drive strength rated for 35 mA sink/source.
Is the MLX90377GVS-ADB-300-SP pin-compatible with earlier Triaxis® sensors?
Yes - the MLX90377GVS-ADB-300-SP uses the DMP-4 package and maintains pin-to-pin compatibility with prior-generation Melexis Triaxis® position sensors in the same footprint, including MLX90363 and MLX90371. This allows drop-in replacement in existing designs without PCB revision, provided firmware supports the enhanced 12-bit resolution and updated register map of the MLX90377GVS-ADB-300-SP.
Does the MLX90377GVS-ADB-300-SP require external decoupling capacitors?
No - the DMP-4 package of the MLX90377GVS-ADB-300-SP integrates internal ceramic decoupling capacitance between VDD and VSS pins. This eliminates the need for external bulk capacitors, simplifies layout, reduces BOM count, and improves high-frequency noise immunity in electrically noisy automotive environments where the MLX90377GVS-ADB-300-SP is deployed.
What functional safety level does the MLX90377GVS-ADB-300-SP achieve?
The MLX90377GVS-ADB-300-SP is certified ISO26262 ASIL-B capable for its analog output mode as a Safety Element out of Context (SEooC). This includes documented safety mechanisms such as watchdog timers, memory ECC, and diagnostic coverage for ADC and signal path integrity - all validated per MLX90377 safety manual. It does not meet ASIL-C for analog output; SENT/PWM variants (e.g., ADB-330) are required for ASIL-C.
Can the MLX90377GVS-ADB-300-SP operate from a 12 V vehicle battery?
Yes - the MLX90377GVS-ADB-300-SP supports 6–18 V battery-supplied operation in PWM mode, with built-in reverse-polarity protection down to -14 V for up to one hour. Its internal regulators maintain stable core voltage across wide input transients, making it suitable for direct connection to automotive battery rails without external LDO or protection circuitry - a key design advantage for throttle and pedal modules using the MLX90377GVS-ADB-300-SP.
