Product details
Overview
MLX90377GVS-ADB-313-SP from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for rotary or linear non-contact sensing. It delivers 12-bit resolution analog and PWM outputs in High Speed Mode, operates from -40°C to 160°C, supports 4.5–18 V supply, and is packaged in DMP-4 (PCB-less dual mold). It serves as the primary magnetic position transducer in automotive throttle and pedal systems.
For engineers reviewing the MLX90377GVS-ADB-313-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 package compatibility with legacy Triaxis® sensors, programmable high-speed analog/PWM output, stray-field robustness in Standard/Legacy Mode, ASIL-B functional safety compliance for analog mode, and 12-bit measurement resolution.
Technical Context
The MLX90377GVS-ADB-313-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute angle or linear displacement decoding via on-chip DSP and 12-bit ADC. Its architecture includes analog regulator, digital regulator, temperature sensor, and programmable output stage supporting analog ratiometric and PWM modes.
This variant uses Standard/Legacy Mode (-3xx option code) with High Speed Mode configuration (suffix "1" in ADB-313), delivering faster update rates than Low Power Mode variants. It implements SAE J2716 APR2016 SENT protocol capability but is configured exclusively for analog/PWM output - not reprogrammable in-system to SENT or SPC.

Pinout & Package
DMP-4 package: PCB-less dual-mold construction with 4 leads, optimized for compact, high-reliability automotive mounting. Leads are trimmed and formed per STD2 2.54 mm pitch (per ADB-313's third digit "3").
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains; must be low-impedance connection to system GND |
| 2 | VDD | Main power supply input (4.5–18 V); internal regulators derive analog/digital rails from this pin |
| 3 | OUT | Configurable analog ratiometric or PWM output; push-pull drive capable of 10 mA sink/source |
| 4 | VSS | Second ground terminal; improves thermal dissipation and reduces ground loop impedance in high-noise environments |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true 3D magnetic field decoding for absolute position without mechanical stops or multi-sensor arrays |
| Programmable Transfer Characteristic | Supports 4- or 8-point piecewise-linear calibration, allowing precise linearization across custom mechanical stroke or rotation ranges |
| High-Speed Analog/PWM Output | Enables >10 kHz signal bandwidth in High Speed Mode (ADB-31x), suitable for closed-loop engine control feedback |
| On-Chip Signal Processing | DSP-based filtering, temperature compensation, and diagnostics reduce external component count and improve EMI resilience |
| Robust Power Architecture | Reverse polarity protection (-14 V), overvoltage tolerance (37 V), and 175°C junction rating ensure survivability in harsh automotive transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVS-ADB-310-SP | Identical DMP-4 package and High Speed Mode, but delivered in standard RE tape-and-reel (2500 pcs/reel) vs. RX face-down orientation | No functional difference; RX variant ensures consistent die orientation during automated placement for optical alignment-critical assemblies | Select MLX90377GVS-ADB-313-SP when face-down orientation is required for vision-guided pick-and-place or conformal coating processes. |
| MLX90377GDC-ADB-310-SP | Same output mode and firmware revision, but SOIC-8 package (8-pin, gull-wing) instead of DMP-4 (4-lead, PCB-less) | SOIC-8 requires PCB footprint change and lacks DMP-4's direct-mount mechanical robustness; higher thermal resistance (RθJA = 120°C/W vs. 65°C/W) | Choose MLX90377GDC-ADB-310-SP only if legacy SOIC-8 layout reuse is mandatory and thermal derating is acceptable. |
Compared with MLX90377GVS-ADB-310-SP, the -313 variant adds face-down tape orientation for precision placement; compared with MLX90377GDC-ADB-310-SP, it replaces SOIC-8 with DMP-4 for direct mechanical integration, lower thermal resistance, and legacy Triaxis® footprint compatibility - critical for high-volume automotive production.

FAQ
What output protocols does the MLX90377GVS-ADB-313-SP support?
The MLX90377GVS-ADB-313-SP is factory-configured for Standard/Legacy Mode with High Speed analog ratiometric and PWM output only. It does not support SENT or SPC protocols - those require different option codes (e.g., ADB-33x or ADB-38x) and cannot be reprogrammed post-manufacture. The MLX90377GVS-ADB-313-SP delivers 12-bit resolution signals with fast update timing optimized for closed-loop control loops.
Is the MLX90377GVS-ADB-313-SP pin-compatible with earlier Triaxis® DMP-4 sensors?
Yes, the MLX90377GVS-ADB-313-SP maintains pin-to-pin compatibility with prior-generation Melexis Triaxis® DMP-4 position sensors, including MLX90363 and MLX90364 in DMP-4 package. Its 4-pin layout (VSS-VDD-OUT-VSS) and STD2 2.54 mm lead form allow direct drop-in replacement without PCB redesign, preserving mechanical mounting and thermal interface integrity.
What functional safety level does the MLX90377GVS-ADB-313-SP achieve in analog mode?
The MLX90377GVS-ADB-313-SP is ISO 26262 ASIL-B capable for analog output mode as a Safety Element out of Context (SEooC). This certification covers diagnostic coverage, fault handling time interval, and hardware metrics validated per Melexis' safety manual. It does not achieve ASIL-C in analog mode - that rating applies only to SENT, PWM, and SPC output configurations per the datasheet.
Can the MLX90377GVS-ADB-313-SP operate directly from a 12 V vehicle battery?
Yes, the MLX90377GVS-ADB-313-SP supports 6–18 V supply in PWM mode, enabling direct connection to an automotive battery rail without external regulation. Its reverse polarity protection (-14 V) and overvoltage tolerance (37 V transient) meet ISO 7637-2 pulse requirements. For analog mode, regulated 5 V is recommended to maintain ratiometric accuracy, though 4.5–5.5 V operation is specified.
What is the meaning of "ADB-313" in the MLX90377GVS-ADB-313-SP part number?
In MLX90377GVS-ADB-313-SP, "ADB" indicates standard chip revision; "3" denotes Standard/Legacy Mode (not stray-field immune); "1" specifies High Speed Mode for analog/PWM output; and "3" defines DMP-4 Trim & Form STD2 2.54 mm lead configuration. The "VS" suffix confirms DMP-4 package, and "SP" denotes sample packaging - distinct from production RE/RX reels.
