Product details
Overview
MLX90371GGO-BCC-500-SP from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary position output with 12-bit resolution, ±10° angular accuracy, and stray-field immunity in high-field rotary mode. It operates from -40°C to +160°C, supports programmable ratiometric analog or PWM output, and is qualified per ISO 26262 ASIL-B as a Safety Element out of Context.
For engineers reviewing the MLX90371GGO-BCC-500-SP datasheet, pinout, applications, or equivalent options, this device serves as a robust, programmable, automotive-grade absolute position sensor for throttle, pedal, steering, and ride-height systems requiring high EMC resilience and functional safety compliance.
Technical Context
The MLX90371GGO-BCC-500-SP implements Triaxis® Hall sensing with on-chip DSP, ADC, and NVRAM to decode absolute angular position from 3D magnetic flux density (BX/BY/BZ). Its architecture includes a 12-bit analog output stage, 12-bit PWM generator, FIR/EMA filtering, and programmable transfer characteristics (4/8-point LNR or 16/32-segment PWL).
This variant uses TSSOP-16 packaging with dual-die isolation, operates at 4.5–5.5 V, draws 6–10 mA supply current in Standard/Legacy mode, and features latency of 440–462 μs and step response up to 5.1 ms depending on filter configuration - all validated for rotary stray-field immune operation under high-field magnetic conditions (BZ ≥ 100 mT).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - supports under-hood automotive placement without external thermal derating. |
| Output Resolution | 12-bit - delivers 0.088° angular granularity over 360° full-scale rotation. |
| Angular Accuracy | ±10° (thermal) - specified for full temperature range, enabling reliable position feedback in harsh environments. |
| Supply Voltage | 4.5–5.5 V - compatible with standard 5 V automotive power rails and regulator outputs. |
| Latency Time | 440–462 μs - ensures real-time control loop compatibility for fast-acting systems like electronic throttle control. |
| PWM Frequency | 150–2000 Hz - configurable for noise-immune digital transmission with ±5% tolerance over temperature and aging. |
| Magnetic Mode | Rotary Stray-Field Immune – High-Field Variant - requires BZ ≥ 100 mT; rejects orthogonal stray fields up to ±10 mT. |
| Safety Certification | ISO 26262 ASIL-B SEooC - enables integration into ASIL-B subsystems without additional hardware safety mechanisms. |
Pinout & Package
TSSOP-16 package with dual-die isolation; 4.4 mm × 5.0 mm footprint, 1.0 mm height, lead pitch 0.65 mm. Pins are arranged for optimal EMC: unused pins (Not Used1/2, Test1/2) must be grounded per design guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | On-chip regulator decoupling - requires 100 nF ceramic capacitor to VSS per die for stable internal voltage generation. |
| 2, 10, 16 | VSSA1 / VSSA2 / VSSD1 | Analog/digital ground - separate analog and digital ground paths reduce noise coupling in precision signal chain. |
| 3, 11 | VDD1 / VDD2 | Primary supply input - dual supply inputs support redundancy and improved fault detection in safety-critical designs. |
| 4, 12 | Test Input1 / Test Input2 | Factory test access - not intended for end-user use; recommended to tie to VSS for EMC integrity. |
| 5, 13 | Test2 / Test1 | Factory test access - unused in application; grounding prevents floating node noise injection. |
| 6, 15 | OUT2 / OUT1 | Dual independent outputs - supports redundant or differential signaling; each configurable as analog or PWM. |
| 7, 14 | Not Used2 / Not Used1 | No internal connection - must be connected to VSS to minimize EMI susceptibility and ensure signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous BX/BY/BZ measurement enables true absolute angle decoding without mechanical cam or multi-sensor alignment. |
| Programmable Transfer Curve | Supports 4/8-point linear interpolation or 16/32-segment piecewise-linear mapping - eliminates external lookup tables and calibration firmware. |
| Stray-Field Immunity | Rejects interfering magnetic fields up to ±10 mT orthogonal to sensing axis - critical for engine bay deployment near motors or solenoids. |
| ASIL-B SEooC Certification | Includes diagnostic coverage for memory, clock, watchdog, and signal path - reduces FMEDA effort for system-level ASIL-B compliance. |
| Dual-Die Isolation (TSSOP-16) | Galvanic isolation between dice enables redundant signal paths and cross-checking for fail-safe architectures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GGO-BCC-500-SP | Same Triaxis® architecture, but adds integrated EEPROM for factory-programmed calibration data and enhanced diagnostics. | Preferred for new designs requiring zero-field calibration storage and extended diagnostic logging capability. | Select MLX90372 if traceable factory calibration and post-deployment diagnostic history are required. |
| AMS AS5055A-BQFT | 14-bit resolution, SPI interface only, no analog/PWM output; lacks ASIL-B SEooC certification and stray-field immunity specs. | Suitable for non-safety-critical industrial encoders where digital bus communication is mandatory. | Choose AS5055A only when SPI interface and higher resolution outweigh need for automotive safety compliance and analog output flexibility. |
Compared with MLX90371GGO-BCC-500-SP, the MLX90372 offers embedded calibration persistence and richer diagnostics but same pinout and core functionality; the AS5055A provides higher resolution and SPI interface but requires external safety mechanisms and lacks stray-field resilience - making MLX90371GGO-BCC-500-SP the optimal choice for ASIL-B rotary position sensing with analog/PWM flexibility and proven EMC hardening.

FAQ
What is the magnetic field requirement for MLX90371GGO-BCC-500-SP in Rotary Stray-Field Immune – High-Field Mode?
The MLX90371GGO-BCC-500-SP requires a minimum Z-axis magnetic flux density (BZ) of 100 mT in Rotary Stray-Field Immune – High-Field Mode, with in-plane components (BX/BY) ≤25 mT. This configuration ensures ±10° angular accuracy and immunity to stray fields up to ±10 mT orthogonal to the sensing axis - verified per datasheet Section 8.2 and Table 9.1.3.
Does MLX90371GGO-BCC-500-SP support both analog and PWM output simultaneously?
No, MLX90371GGO-BCC-500-SP does not support simultaneous analog and PWM output. It provides one output mode per configuration: either ratiometric analog (0–100% VDD) or PWM (150–2000 Hz), selected via end-user programming. The TSSOP-16 package offers two independent outputs (OUT1/OUT2), each configurable separately - enabling dual-mode redundancy but not concurrent operation on a single channel.
What is the purpose of the dual-die structure in the TSSOP-16 package of MLX90371GGO-BCC-500-SP?
The dual-die structure in the TSSOP-16 package of MLX90371GGO-BCC-500-SP provides galvanic isolation between two independent Triaxis® sensor channels, supporting hardware-level redundancy, cross-comparison diagnostics, and fail-safe operation. Per datasheet Section 5, isolation resistance exceeds 4 MΩ between dice - enabling ASIL-B system architectures without external isolation components.
Can MLX90371GGO-BCC-500-SP be programmed in-system after soldering?
Yes, MLX90371GGO-BCC-500-SP supports in-system programming via the TEST pins using Melexis' PTM (Programmable Triaxis® Module) protocol. All end-user programmable items - including output mode, transfer characteristic, filter settings, and diagnostic thresholds - can be configured post-soldering using standard SPI-compatible programmers and Melexis' official GUI tools, as documented in Sections 11 and 13 of the datasheet.
What is the maximum allowable supply voltage transient for MLX90371GGO-BCC-500-SP?
The MLX90371GGO-BCC-500-SP tolerates supply voltage transients up to 45 V for durations under 1 minute and up to 28 V continuously, per Absolute Maximum Ratings (Table 6). Reverse voltage protection extends to -14 V at room temperature. These ratings enable direct connection to 12 V/24 V automotive battery rails with standard TVS clamping, without external regulators or overvoltage circuitry.
