Product details
Overview
MLX90371GVS-BCC-100-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 over -40°C to +160°C, and stray-field immunity in Rotary Stray-Field Immune Mode. It operates from 4.5–5.5 V, draws 6–10 mA, and supports ratiometric analog or PWM output for automotive pedal and throttle sensing.
For engineers reviewing the MLX90371GVS-BCC-100-SP datasheet, pinout, applications, or equivalent options, key selection factors include its DMP-4 package footprint, programmable 4-/8-point linear transfer characteristic, ISO26262 ASIL-B safety element out-of-context qualification, and built-in diagnostics including broken-wire detection and intelligent watchdog.
Technical Context
The MLX90371GVS-BCC-100-SP implements Triaxis® Hall technology with on-chip DSP, ADC, and NVRAM to compute absolute angle from 3D magnetic flux density. Its architecture includes dual-path signal processing (analog and PWM), FIR or exponential moving average filtering, and configurable diagnostic modes (active/passive) with programmable clamping levels.
This variant uses the DMP-4 package with straight leads (STD0), integrates 100 nF decoupling capacitance, and is factory-configured for Rotary Stray-Field Immune Mode – Low-Field Variant per BCC-100 option code. It features 48-bit unique ID, thermal compensation, and reverse-polarity/overvoltage protection on VDD.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-BCC-100-SP | Same DMP-4 package and BCC-100 configuration but adds EEPROM-based user-programmable calibration and enhanced diagnostic coverage. | Required where end-of-line calibration or field updates are needed; not drop-in due to extended programming interface requirements. | Select when production calibration flexibility or higher diagnostic coverage (beyond ASIL-B SEooC) is mandatory. |
| AMS AS5055A-DSO | SOIC-8 package, 12-bit resolution, ±0.5° typical accuracy, but lacks stray-field immunity and ASIL-B certification. | Suitable for non-safety-critical industrial encoders; requires external shielding and failsafe monitoring circuitry for automotive use. | Select only for cost-sensitive, non-automotive applications where stray fields are absent and safety certification is unnecessary. |
Compared with MLX90371GVS-BCC-100-SP, MLX90372GVS-BCC-100-SP offers field-programmable calibration but increases system complexity, while AMS AS5055A-DSO delivers higher base accuracy but cannot meet automotive stray-field or functional safety requirements without added hardware and software overhead.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-100-SP?
The MLX90371GVS-BCC-100-SP is qualified for continuous operation from -40°C to +160°C ambient temperature, with junction temperature up to +175°C. This rating is validated per AEC-Q100 Grade 0 and supports placement in demanding under-hood locations such as throttle bodies and brake modules where the MLX90371GVS-BCC-100-SP maintains full functionality and accuracy without derating.
Does the MLX90371GVS-BCC-100-SP require external decoupling capacitors?
No, the MLX90371GVS-BCC-100-SP in DMP-4 package includes an integrated 100 nF decoupling capacitor per the BCC-100 option code. This eliminates the need for external VDEC capacitors, reduces PCB area, and improves reliability by removing solder joint failure points - a key advantage of the MLX90371GVS-BCC-100-SP in compact automotive modules.
How is stray-field immunity implemented in the MLX90371GVS-BCC-100-SP?
The MLX90371GVS-BCC-100-SP achieves stray-field immunity through its Rotary Stray-Field Immune Mode – Low-Field Variant (BCC-100), which uses differential Triaxis® sensing and proprietary DSP algorithms to reject external magnetic interference up to ±1 mT while preserving ±10° angular accuracy. This capability is intrinsic to the MLX90371GVS-BCC-100-SP's firmware and does not require external shielding or magnet repositioning.
Can the MLX90371GVS-BCC-100-SP output both analog and PWM signals simultaneously?
No, the MLX90371GVS-BCC-100-SP supports either ratiometric analog or PWM output - selected during programming - but not both concurrently. The output mode is stored in NVRAM and persists across power cycles. This single-output constraint is fixed in the MLX90371GVS-BCC-100-SP's architecture and requires hardware or firmware coordination if dual-signal redundancy is needed.
Is the MLX90371GVS-BCC-100-SP certified to ISO26262 ASIL-B?
Yes, the MLX90371GVS-BCC-100-SP is certified as a Safety Element out of Context (SEooC) at ASIL-B level per ISO26262-5:2018. This includes documented safety mechanisms (ECC memory, diagnostic watchdog, voltage/temperature monitoring), FMEDA reports, and safety manual - all applicable to the MLX90371GVS-BCC-100-SP without modification when integrated per Melexis guidelines.
