Product details
Overview
MLX90377GVS-ADB-308-SP from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for non-contact rotary or linear sensing. It delivers 12-bit ratiometric analog and PWM outputs in Standard/Legacy Mode, operates from -40°C to 160°C, supports up to 18 V supply, and features stray-field immunity in its configured mode. It is used in automotive throttle and pedal position sensing where robustness and ASIL-B functional safety compliance are required.
For engineers reviewing the MLX90377GVS-ADB-308-SP datasheet, pinout, applications, or equivalent options, key selection criteria include DMP-4 package compatibility, low-power analog/PWM output configuration (ADB-308), SAE J2716 SENT readiness, ISO 26262 ASIL-B capability for analog mode, and built-in decoupling capacitors enabling simplified PCB layout.
Technical Context
The MLX90377GVS-ADB-308-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, a 12-bit ADC, DSP-based signal conditioning, and programmable transfer characteristics (4/8/16/32-point piecewise-linear). Its DMP-4 package embeds decoupling capacitors and uses straight leads (STD0 configuration per ADB-308).
This variant is factory-configured for Standard/Legacy Mode with analog/PWM output and low-power operation, supporting ratiometric analog output (0–100% VDD) and PWM (50–90% duty cycle), with startup time ≤ 5 ms and latency < 1.5 ms under typical conditions.
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-SP | Same DMP-4 package and analog/PWM output, but configured for High Speed Mode (12 mA typical IDD) | Higher bandwidth (≤2.5 kHz update rate) and faster startup (≤3 ms), suited for dynamic pedal response | Select ADB-310 when system requires sub-3 ms latency and higher sampling rate; ADB-308 preferred for lower power budget |
| MLX90371GVS-ADB-308-SP | Legacy Triaxis® device in same DMP-4 package; 10-bit resolution, no ASIL-B certification, fixed 4-point LNR | Limited to legacy designs requiring backward compatibility; lacks SENT/SPC flexibility and enhanced diagnostics | Choose MLX90371 only for cost-sensitive, non-safety-critical replacements where 10-bit resolution suffices |
Compared with MLX90377GVS-ADB-308-SP, the ADB-310 variant trades 1 mA higher quiescent current for improved dynamic response, while the MLX90371 offers pin-compatible migration at lower resolution and no functional safety qualification - making ADB-308 the optimal balance of power, precision, and ASIL-B compliance for new designs.

FAQ
What output protocols does the MLX90377GVS-ADB-308-SP support?
The MLX90377GVS-ADB-308-SP is factory-configured for Standard/Legacy Mode with analog ratiometric and PWM outputs only. SENT and SPC protocols are not enabled - they require different option codes (e.g., ADB-330 or ADB-380) and cannot be reprogrammed in the field. This fixed configuration ensures deterministic behavior for safety-critical analog feedback loops.
Is the MLX90377GVS-ADB-308-SP pin-compatible with earlier Triaxis® sensors in DMP-4 packages?
Yes, the MLX90377GVS-ADB-308-SP maintains pin-to-pin compatibility with prior-generation Triaxis® devices in DMP-4 packages, including MLX90363 and MLX90371. Its 4-terminal layout (VSS-VDD-OUT-VSS) and STD0 lead form allow drop-in replacement without PCB redesign, provided the application operates within the same analog/PWM output and temperature requirements.
Does the MLX90377GVS-ADB-308-SP require external decoupling capacitors?
No, the MLX90377GVS-ADB-308-SP in DMP-4 package integrates decoupling capacitors internally. This eliminates the need for external bulk capacitance on the PCB, reducing component count and board area - especially valuable in compact automotive modules where space and reliability are critical.
What functional safety level does the MLX90377GVS-ADB-308-SP achieve in analog mode?
The MLX90377GVS-ADB-308-SP is ISO 26262 ASIL-B capable for analog output mode as a Safety Element out of Context (SEooC). It includes built-in diagnostics such as broken-wire detection on VDD and VSS, internal voltage monitoring, and configurable watchdog timers - all documented in the official Melexis Safety Manual for integration into ASIL-B systems.
How is stray-field immunity implemented in the MLX90377GVS-ADB-308-SP?
The MLX90377GVS-ADB-308-SP operates in Standard/Legacy Mode (-3xx option code), which provides baseline stray-field immunity through Triaxis® 3D Hall sensing and on-chip differential signal processing. Unlike -2xx or -5xx variants, it does not employ dedicated stray-field compensation algorithms but achieves sufficient rejection for most under-hood applications using optimized magnetic circuit design.
