Product details
Overview
MLX90377GVE-ADB-110-SP from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for rotary applications in high-EMI automotive environments. It delivers 12-bit resolution analog/PWM output, operates from -40°C to +160°C, supports Rotary Stray-Field Immune Mode (Low Field variant), and is qualified to ISO 26262 ASIL-C for SENT/PWM/SPC outputs. It enables non-contact throttle or steering wheel position sensing with built-in stray-field immunity.
For engineers reviewing the MLX90377GVE-ADB-110-SP datasheet, pinout, applications, or equivalent options, this page provides verified functional context, SMP-3 package terminal mapping, real-world accuracy specs under stray-field conditions, and validated alternatives for automotive position-sensing designs requiring ASIL-C compliance and magnetic robustness.
Technical Context
The MLX90377GVE-ADB-110-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute angular position decoding up to 360° without external magnets or complex circuitry. Its on-chip DSP performs real-time signal conditioning, piecewise-linearization (up to 32 segments), and programmable transfer characteristics tailored for low-field rotary configurations.
This variant implements Rotary Stray-Field Immune Mode (–1xx option code), optimized for operation in ≤25 mT stray fields using internal magnetic concentrators and differential sensing. It supports only Analog and PWM output modes in High Speed configuration (option "1"), with startup time ≤3 ms and latency <1.5 ms - confirmed in Section 7.2 and Table 9.2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Resolution | 12-bit (4096 steps) for analog and PWM outputs - enables sub-degree angular precision in 0–360° rotary systems. |
| Operating Temperature | -40°C to +160°C - supports under-hood automotive placement without external thermal derating. |
| Supply Voltage Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - accommodates both ECU-supplied and direct-battery interfaces. |
| Stray-Field Immunity | ≤25 mT (Rotary Low-Field variant, –1xx) - maintains accuracy in proximity to motors, solenoids, or adjacent sensors. |
| Functional Safety | ISO 26262 ASIL-C capable for PWM/SENT/SPC outputs; ASIL-B for analog - certified as Safety Element out of Context (SEooC). |
| Startup Time | ≤3 ms in High Speed mode - ensures rapid system readiness after ignition or wake-up events. |
| Latency | <1.5 ms average - critical for closed-loop control loops in throttle or brake-by-wire systems. |
Pinout & Package
SMP-3 is a PCB-less single-mold package with three solderable terminals and two test pads. It integrates decoupling capacitance, eliminating need for external bulk capacitors. Terminal layout matches standard 2.54 mm pitch for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Power supply input | Accepts 4.5–18 V; reverse-polarity protected to -14 V; powers internal analog/digital regulators. |
| 2 (OUT) | Programmable output driver | Delivers ratiometric analog (0.5–4.5 V) or PWM (10–90% duty cycle); push-pull or open-drain configurable. |
| 3 (VSS) | Ground reference | Primary return path; used for broken-wire detection (BVSSPU/BVSSPD diagnostics per Table 10). |
| a (INPUT) | Factory test interface | Not user-accessible in final application; tied internally during normal operation. |
| b (TEST) | Factory test interface | Reserved for Melexis production testing; no functional role in end-use circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall sensing | Measures Bx, By, Bz simultaneously to resolve absolute angle from magnet rotation - eliminates need for dual-Hall or resolver solutions. |
| Rotary Stray-Field Immunity (Low Field) | Validated operation under ≤25 mT external interference - enables placement near high-current actuators without shielding. |
| Programmable transfer characteristic | Configurable 4-, 8-, 16-, or 32-point piecewise-linear curve - matches mechanical travel profile without external lookup tables. |
| Integrated diagnostics | Includes broken-wire detection (VDD/VSS), watchdog timers (AWD/IWD), and CRC-protected SENT/SPC frames - reduces external safety monitoring IC count. |
| High-speed analog/PWM mode | Startup ≤3 ms and latency <1.5 ms - meets real-time response requirements for engine management and chassis control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVE-ADB-310-SP | Standard/Legacy Mode (not stray-field immune); same SMP-3 package, 12-bit analog/PWM, High Speed. | Lacks rotary stray-field immunity - requires physical shielding or increased spacing from noise sources. | Select when magnetic environment is controlled and cost optimization is prioritized over field robustness. |
| MLX90377GVE-ADB-510-SP | Rotary Stray-Field Immune Mode (High Field variant); supports ≥50 mT interference tolerance. | Higher stray-field margin but consumes ~1.5× more current (15 mA vs. 13.5 mA typical) in High Speed mode. | Choose for extreme EMI zones (e.g., near traction inverters) where >25 mT immunity is mandated. |
Compared with MLX90377GVE-ADB-110-SP, the ADB-310-SP trades stray-field immunity for lower system cost and simpler layout, while the ADB-510-SP extends interference tolerance at the expense of higher quiescent current - making the ADB-110-SP the optimal balance for mainstream automotive throttle and steering applications.

FAQ
What output protocols does the MLX90377GVE-ADB-110-SP support?
The MLX90377GVE-ADB-110-SP supports only analog ratiometric and PWM output modes in High Speed configuration, as defined by its ADB-110 option code. SENT and SPC are not enabled for this variant - they require ADB-130 or ADB-180 codes respectively, and cannot be reprogrammed post-manufacture per Table 2 of the datasheet.
Is the MLX90377GVE-ADB-110-SP pin-compatible with other MLX90377 variants in SMP-3 package?
Yes, all MLX90377 variants in SMP-3 package - including MLX90377GVE-ADB-110-SP, MLX90377GVE-ADB-310-SP, and MLX90377GVE-ADB-510-SP - share identical pinout (VDD, OUT, VSS, plus INPUT/TEST test pads) and mechanical footprint per Section 19.4 of the datasheet, enabling drop-in replacement within the same package family.
What is the maximum stray magnetic field the MLX90377GVE-ADB-110-SP can tolerate?
The MLX90377GVE-ADB-110-SP is rated for ≤25 mT stray-field immunity in Rotary Stray-Field Immune Mode (Low Field variant), as specified in Section 8.1 and Table 9.2 of the datasheet. This performance is achieved via on-chip magnetic concentrators and differential signal processing - not external shielding.
Does the MLX90377GVE-ADB-110-SP require external decoupling capacitors?
No. The MLX90377GVE-ADB-110-SP in SMP-3 package integrates internal decoupling capacitance, as confirmed in Section 16.4 and Figure 3 of the datasheet. No external VDEC capacitor is needed - simplifying PCB layout and reducing BOM count.
What functional safety level is certified for the MLX90377GVE-ADB-110-SP analog output?
The MLX90377GVE-ADB-110-SP analog output mode is ISO 26262 ASIL-B capable, while its PWM output (enabled in this variant) achieves ASIL-C compliance. Both are certified as Safety Element out of Context (SEooC), with diagnostic coverage detailed in Section 15 of the datasheet.
