Product details
Overview
MLX90371GVS-BCC-101-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 serves as a contactless replacement for potentiometers in automotive throttle and pedal sensing.
For engineers reviewing the MLX90371GVS-BCC-101-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 package footprint, programmable PWM/analog output, ISO26262 ASIL-B safety compliance, and 100 mT Z-axis field requirement for rotary mode operation.
Technical Context
The MLX90371GVS-BCC-101-SP implements Triaxis® Hall sensing with on-chip DSP, ADC, and NVRAM to compute absolute angle from 3D magnetic flux density. Its architecture includes a 12-bit analog output stage and 12-bit PWM generator, both ratiometric to VDD, with configurable FIR filtering (FIR1/FIR11/FIR1111) and latency as low as 440 μs.
This variant operates exclusively in Rotary Stray-Field Immune Mode (BCC-101), requiring a magnet configuration with ≥4 poles and minimum 25 mT in-plane (BX/BY) and 100 mT axial (BZ) field strength. It supports end-user programming of transfer characteristics via 4/8-point LNR or 16/32-segment PWL tables stored in NVRAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-BCC-100-SP | Same DMP-4 package and Rotary Stray-Field Immune Mode, but uses 100 nF output capacitor (BCC-100) vs. 10 nF (BCC-101) | Lower output impedance and reduced noise sensitivity - preferred for long cable runs or noisy environments | Select BCC-100 when EMC robustness is prioritized over response speed; BCC-101 offers faster slew rate due to smaller capacitor |
| MLX90371GVS-BCC-151-SP | Identical DMP-4 package and Rotary Stray-Field Immune Mode, but with STD4 2.54 mm lead form (BCC-151) instead of STD1 (BCC-101) | STD4 lead geometry improves coplanarity and solder joint reliability - recommended for new designs per datasheet section 18.3.4 | Choose BCC-151 for enhanced manufacturability and long-term supply continuity; BCC-101 remains valid but not preferred for new designs |
Compared with MLX90371GVS-BCC-101-SP, the BCC-100 variant trades slightly slower dynamic response for improved noise immunity, while the BCC-151 variant maintains identical electrical performance but upgrades lead form for higher assembly yield and IPC Class 3 compliance.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-101-SP?
The MLX90371GVS-BCC-101-SP is qualified for continuous operation from -40°C to +160°C ambient temperature, making it suitable for under-hood automotive applications such as throttle bodies and brake pedals where thermal extremes are common. This rating is validated per AEC-Q100 Grade 0 and applies to the DMP-4 package configuration used in this variant.
Does the MLX90371GVS-BCC-101-SP require external programming before use?
Yes, the MLX90371GVS-BCC-101-SP ships unprogrammed and requires end-user configuration via Melexis' PTM (Programmable Triaxis® Module) software to set output mode (analog/PWM), transfer characteristic, diagnostic settings, and magnetic calibration parameters. The NVRAM retains these settings permanently after programming, and no factory default configuration is preloaded.
What magnetic field strength is required for proper operation of the MLX90371GVS-BCC-101-SP?
The MLX90371GVS-BCC-101-SP requires a minimum 100 mT axial (BZ) magnetic field and ≥25 mT in-plane (BX/BY) field when configured in Rotary Stray-Field Immune Mode (BCC-101). These values are specified in datasheet section 8.1 and must be verified with actual magnet geometry and air gap during mechanical design.
Can the MLX90371GVS-BCC-101-SP be used in linear position sensing applications?
No - the MLX90371GVS-BCC-101-SP is specifically configured for rotary position sensing in Stray-Field Immune Mode (BCC-101). For linear applications, Melexis specifies BCC-200 or BCC-201 variants. Using MLX90371GVS-BCC-101-SP in linear configurations will result in degraded accuracy and invalid calibration due to mismatched magnetic field optimization.
What is the significance of the '101' in the MLX90371GVS-BCC-101-SP part number?
The '101' suffix in MLX90371GVS-BCC-101-SP indicates three attributes: '1' = Rotary Stray-Field Immune Mode application, '0' = 10 nF internal output capacitor, and '1' = STD1 2.54 mm lead form per datasheet Table 1. This distinguishes it from variants like BCC-100 (100 nF cap) or BCC-151 (STD4 lead form), all sharing the same core IC die and DMP-4 package.
