Product details
Overview
MLX90371GGO-BCC-500-RE from Melexis is a Triaxis® monolithic position processor IC that measures all three orthogonal magnetic field components (BX, BY, BZ) to deliver absolute rotary position output with 12-bit resolution and ±10-bit thermal accuracy. It operates over -40°C to +160°C, supports programmable ratiometric analog or PWM output, and implements Rotary Stray-Field Immune Mode – High-Field Variant for robust operation in automotive throttle and pedal sensing.
For engineers reviewing the MLX90371GGO-BCC-500-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16), confirmed pin functions, real-world accuracy specs under high-field rotary conditions, ISO26262 ASIL-B safety compliance, and validated alternatives for automotive position sensing designs.
Technical Context
The MLX90371GGO-BCC-500-RE integrates on-chip DSP, 12-bit ADC, temperature sensor, and dual-die TSSOP-16 isolation to enable stray-field immune angle decoding. Its architecture uses Triaxis® Hall sensing with integrated magnetic concentrators and programmable FIR filtering (FIR1/FIR11/FIR1111) to suppress interference while maintaining latency as low as 440 μs.
This variant implements Rotary Stray-Field Immune Mode – High-Field Variant per datasheet Section 8.2, requiring ≥100 mT Z-component flux density and supporting 4/8-point linearization or 16/32-segment piecewise-linear transfer characteristics. It delivers analog output with 0.5–97.5% VDD saturation range and PWM output at 150–2000 Hz with ±5% frequency tolerance.

FAQ
What is the magnetic field requirement for MLX90371GGO-BCC-500-RE in Rotary Stray-Field Immune Mode – High-Field Variant?
The MLX90371GGO-BCC-500-RE requires a minimum Z-component magnetic flux density (BZ) of 100 mT in Rotary Stray-Field Immune Mode – High-Field Variant, as specified in datasheet Section 8.2. This high-field threshold enables robust rejection of external stray fields up to ±100 mT while maintaining full 12-bit linearity and thermal accuracy across -40°C to +160°C.
Does MLX90371GGO-BCC-500-RE support both analog and PWM output simultaneously?
No, the MLX90371GGO-BCC-500-RE supports either ratiometric analog output or PWM output-not both simultaneously-as configured during end-user programming. The output mode is selected via the USEROPTION_OUTMODE parameter in NVRAM; switching requires reprogramming and power cycle. Both modes share the same OUT1 and OUT2 pins in TSSOP-16 package.
What safety documentation is provided for MLX90371GGO-BCC-500-RE?
MLX90371GGO-BCC-500-RE is certified as an ISO26262 ASIL-B Safety Element out-of-Context (SEooC), with a dedicated Safety Manual (document MLX90371-SM) covering fault tree analysis, diagnostic coverage metrics, FIT rates, and integration guidelines. The device includes built-in diagnostics such as broken-wire detection, overvoltage protection, and intelligent watchdog timers-all verified per ASIL-B requirements.
How is the 12-bit resolution of MLX90371GGO-BCC-500-RE achieved in practice?
The MLX90371GGO-BCC-500-RE achieves true 12-bit resolution through on-chip 12-bit ADC sampling of Triaxis® Hall signals, followed by DSP-based interpolation and linearization. In Rotary Stray-Field Immune Mode – High-Field Variant, this delivers 4096 discrete position steps over 0–360°, with thermal accuracy maintained at ±10 LSB across the full -40°C to +160°C operating range per datasheet Section 9.2.
Can MLX90371GGO-BCC-500-RE be used in linear position sensing applications?
Yes, the MLX90371GGO-BCC-500-RE can be configured for linear position sensing via its programmable transfer characteristic and Triaxis® field vector decoding, but it is optimized for rotary use in High-Field Variant mode. For dedicated linear applications, Melexis recommends MLX90371GGO-BCC-200-RE (Linear Stray-Field Immune Mode), which uses different internal calibration and magnetic thresholds tailored to linear displacement profiles.
