Product details

Overview

MLX90371GVS-BCC-301-SP from Melexis is a Triaxis® monolithic position processor IC that senses BX, BY, and BZ magnetic field components to deliver absolute rotary or linear position output with 12-bit resolution, ±10-bit thermal accuracy, and programmable analog or PWM output. It operates from -40°C to +160°C in DMP-4 package and supports ISO26262 ASIL-B safety compliance for automotive pedal, throttle, and steering applications.

For engineers reviewing the MLX90371GVS-BCC-301-SP datasheet, pinout, applications, or equivalent options, key selection criteria include stray-field immune mode compatibility, DMP-4 mechanical form factor, programmable transfer characteristic (4/8-point LNR or 16/32-segment PWL), ratiometric analog vs. PWM output configuration, and end-user programmability of gain, zero point, and diagnostics.

Technical Context

The MLX90371GVS-BCC-301-SP implements Triaxis® Hall sensing with integrated DSP, ADC, and on-chip ROM firmware to compute absolute angular or linear position from 3-axis flux density inputs. Its architecture includes dual-path signal processing: analog front-end with programmable gain (GAINMIN/GAINMAX) and digital path with FIR or exponential moving average filtering.

This variant uses Standard/Legacy Mode (BCC-301), enabling backward compatibility with prior-generation MLX9036x devices. It features a single-output channel, 48-bit user-programmable ID, and configurable diagnostic modes including active PWM fault signaling and passive broken-wire detection on VDD/VSS lines.

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-301-SP	Same DMP-4 package and pinout; adds dual-output capability (OUT1/OUT2) and extended diagnostics including temperature reporting.	Required where redundancy or dual-signal validation is mandated (e.g., ASIL-C systems); not drop-in for single-output designs.	Select MLX90372GVS-BCC-301-SP only if dual-channel output or enhanced diagnostics are needed; otherwise MLX90371GVS-BCC-301-SP provides optimal cost/performance balance.
MLX90363GDC-ABD-000-TU	SOIC-8 package with different pinout (8-pin vs. DMP-4's 4-pin); lacks DMP-4's vibration resistance and PCB-less mounting; same Standard/Legacy Mode functionality.	Suitable for board-level integration where PCB space allows; not mechanically interchangeable with DMP-4 due to footprint and leadform differences.	Choose MLX90363GDC-ABD-000-TU only when SOIC-8 is acceptable and board layout permits; MLX90371GVS-BCC-301-SP remains preferred for direct mounting on actuators or pedals.

Compared with MLX90372GVS-BCC-301-SP, the MLX90371GVS-BCC-301-SP offers identical core position processing and safety features in a simpler single-output configuration, reducing BOM count and software complexity. Against MLX90363GDC-ABD-000-TU, it trades package flexibility for superior mechanical robustness and simplified assembly-critical for high-shock automotive subsystems.

FAQ

What is the operating temperature range of the MLX90371GVS-BCC-301-SP?

The MLX90371GVS-BCC-301-SP is qualified for continuous operation from -40°C to +160°C, making it suitable for under-hood automotive applications such as throttle bodies and transmission shifters. This rating applies to the DMP-4 package and is verified per AEC-Q100 Grade 0 stress testing protocols. The device maintains 10-bit thermal accuracy across this full range, ensuring consistent position reporting despite extreme ambient shifts.

Does the MLX90371GVS-BCC-301-SP support both analog and PWM outputs?

Yes, the MLX90371GVS-BCC-301-SP supports selectable ratiometric analog output (0–100% VDD) or PWM output (150–2000 Hz) via end-user programming. The output mode is configured in NVRAM and persists after power cycle. Analog mode provides 12-bit resolution with 200 V/ms slew rate (no load); PWM mode offers programmable frequency and duty-cycle mapping to position, with ±5% frequency tolerance over temperature and aging.

What does "BCC-301" signify in the MLX90371GVS-BCC-301-SP part number?

In MLX90371GVS-BCC-301-SP, "BCC-301" identifies the die version and configuration: "3" denotes Standard/Legacy Mode (backward compatible with MLX9036x), "0" specifies 100 nF internal output capacitor, and "1" indicates STD1 trim-and-form lead geometry (2.54 mm pitch, straight leads). This variant omits advanced stray-field immunity algorithms but retains full programmability and ASIL-B safety features.

Can the MLX90371GVS-BCC-301-SP be programmed in-system?

Yes, the MLX90371GVS-BCC-301-SP supports in-system programming via its I²C-compatible serial interface. All user-configurable parameters-including transfer characteristic (4/8-point LNR or 16/32-segment PWL), zero point (DP), gain (GAINMIN/GAINMAX), filter settings, and diagnostic thresholds-are written to on-chip NVRAM and retained across power cycles. Programming requires Melexis' official PTM software and compatible hardware adapter.

Is the MLX90371GVS-BCC-301-SP compliant with ISO26262 functional safety standards?

Yes, the MLX90371GVS-BCC-301-SP is certified as an ISO26262 ASIL-B Safety Element out of Context (SEooC).
