Product details
Overview
MLX90377GVS-ADB-313-RX from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in DMP-4 package, delivering 12-bit analog and PWM outputs with high-speed mode timing (≤100 µs latency), ASIL-B functional safety compliance for analog/PWM modes, and operation from -40°C to +160°C. It decodes rotary or linear magnet position via Bx/By/Bz field components and targets automotive pedal/throttle sensing.
For engineers reviewing the MLX90377GVS-ADB-313-RX datasheet, pinout, applications, or equivalent options, key selection criteria include DMP-4 PCB-less packaging, high-speed analog/PWM output configuration (ADB-313), stray-field immunity level, SENT protocol incompatibility, and ASIL-B safety certification scope.
Technical Context
The MLX90377GVS-ADB-313-RX integrates a Triaxis® Hall front end, 12-bit ADC, DSP-based signal conditioner, and dual-mode output stage supporting ratiometric analog and PWM signals. Its architecture enables absolute angle measurement up to 360° or linear displacement using a single moving magnet and built-in magnetic concentrator.
This variant operates in Standard/Legacy Mode (-3xx code) with high-speed analog/PWM output (code '1'), uses DMP-4 packaging (4-pin, PCB-less dual mold), and supports programmable transfer characteristics (4/8/16/32-point piecewise-linear). It does not support SENT or SPC protocols per ordering code ADB-313.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Analog ratiometric and PWM only - no SENT/SPC; ADB-313 confirms high-speed analog/PWM configuration. |
| Resolution | 12-bit - delivers 0.088° angular resolution over 360° full scale or equivalent linear precision. |
| Latency (High Speed) | ≤100 µs - enables real-time closed-loop control in throttle/pedal actuation systems. |
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments without derating. |
| Safety Certification | ISO 26262 ASIL-B for analog/PWM outputs - validated safety element out of context (SEooC). |
| Supply Range | 4.5 V to 18 V - supports direct battery connection with reverse polarity and overvoltage protection. |
| Package | DMP-4 - 4-pin, PCB-less dual-mold package with standard straight leads (ADB-3xx suffix '0' or '3'). |
Pinout & Package
DMP-4 is a compact, PCB-less dual-mold package with 4 solderable terminals and integrated decoupling capacitance. It provides mechanical robustness and simplified mounting for space-constrained automotive sensors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog/digital domains; must be low-impedance for EMC and accuracy. |
| 2 | VDD | Primary supply input (4.5–18 V); includes reverse-polarity and overvoltage protection circuitry. |
| 3 | OUT | Push-pull output capable of driving analog (0.5–4.5 V ratiometric) or PWM (0–100% duty cycle) signals. |
| 4 | VSS | Second ground terminal - improves current return path symmetry and reduces thermal resistance. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous Bx/By/Bz field measurement enables true 3D position decoding without external magnets or complex assemblies. |
| Programmable Transfer Curve | Configurable 4-, 8-, 16-, or 32-point piecewise-linear mapping allows precise calibration to mechanical stroke or rotation profiles. |
| Stray-Field Immunity | Standard/Legacy Mode (ADB-313) provides baseline immunity; not enhanced for linear or rotary stray fields (requires -1xx/-2xx/-5xx codes). |
| Integrated Signal Chain | On-chip ADC, DSP, ROM firmware, and temperature sensor eliminate external signal conditioning components. |
| Robust Power Architecture | Reverse polarity protection down to -18 V and overvoltage tolerance up to +37 V enable direct battery interface in harsh environments. |
Applications
| Pedal Position Sensing | Throttle Position Sensing |

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-RE | Identical DMP-4 package and high-speed analog/PWM output, but shipped in standard tape-and-reel (RE) orientation vs. face-down RX. | No functional difference; RX variant optimized for automated pick-and-place with downward-facing die orientation. | Select MLX90377GVS-ADB-310-RE if standard orientation suffices; MLX90377GVS-ADB-313-RX preferred for high-throughput SMT lines requiring face-down placement. |
| MLX90377GDC-ADB-310-RE | SOIC-8 package instead of DMP-4; same ADB-310 high-speed analog/PWM configuration and -40°C to +160°C rating. | Requires PCB footprint and layout change; lacks DMP-4's integrated capacitors and mechanical ruggedness. | Choose MLX90377GDC-ADB-310-RE only when legacy SOIC-8 compatibility or higher pin count is needed; MLX90377GVS-ADB-313-RX offers superior miniaturization and mounting simplicity. |
Compared with MLX90377GVS-ADB-310-RE, the MLX90377GVS-ADB-313-RX provides identical electrical performance but optimized tape orientation for automated assembly; versus MLX90377GDC-ADB-310-RE, it trades SOIC-8's general-purpose layout flexibility for DMP-4's compact, capacitor-integrated, and mechanically robust form factor tailored for space- and reliability-critical automotive sensing.

FAQ
What output protocols does the MLX90377GVS-ADB-313-RX support?
The MLX90377GVS-ADB-313-RX supports only analog ratiometric and PWM output modes. Its ADB-313 option code explicitly designates Standard/Legacy Mode with high-speed analog/PWM configuration; SENT and SPC protocols are disabled and cannot be enabled via programming. This is fixed at factory trim and verified in Table 1 and Section 14.1 of the datasheet.
What is the package type and pin configuration of the MLX90377GVS-ADB-313-RX?
The MLX90377GVS-ADB-313-RX uses the DMP-4 package - a 4-terminal, PCB-less dual-mold construction with pins labeled VSS, VDD, OUT, and VSS. Pin 1 is ground, Pin 2 is supply, Pin 3 is output, and Pin 4 is a second ground terminal. This configuration is confirmed in Section 3.3 and Figure 3 of the datasheet.
Does the MLX90377GVS-ADB-313-RX meet ISO 26262 functional safety requirements?
Yes, the MLX90377GVS-ADB-313-RX is certified as a Safety Element out of Context (SEooC) compliant with ISO 26262 ASIL-B for analog and PWM output modes. It does not achieve ASIL-C rating, which applies only to SENT/SPC variants. This distinction is documented in the Features section and Section 15 of the datasheet.
What is the operating temperature range of the MLX90377GVS-ADB-313-RX?
The MLX90377GVS-ADB-313-RX operates from -40°C to +160°C ambient temperature, matching the 'G' temperature grade defined in Table 2. This range is fully supported across all electrical specifications including supply current, output accuracy, and latency, as stated in Section 6 and Table 8 of the datasheet.
Can the MLX90377GVS-ADB-313-RX be reprogrammed to change its output mode after shipment?
No, the MLX90377GVS-ADB-313-RX output mode is permanently configured during factory programming and cannot be altered by the end user. The ADB-313 option code fixes the device to Standard/Legacy Mode with high-speed analog/PWM output; switching to SENT or SPC requires ordering a different variant such as MLX90377GVS-ADB-330-RX.
