Product details
Overview
MLX90371GVS-BCC-308-RX from Melexis is a Triaxis® monolithic position processor IC that senses all three magnetic field components (BX, BY, BZ) to deliver absolute rotary or linear position output with 12-bit resolution and ±10-bit thermal accuracy. It operates from -40°C to +160°C, supports programmable ratiometric analog or PWM output, and implements ISO26262 ASIL-B safety element out-of-context in Standard/Legacy Mode for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90371GVS-BCC-308-RX datasheet, pinout, applications, or equivalent options, this device delivers stray-field-immune position measurement in DMP-4 package with STD4 2.54mm trim-and-form leads, requiring no external magnet calibration or signal conditioning circuitry.
Technical Context
The MLX90371GVS-BCC-308-RX uses integrated IMC (Integrated Magnetic Concentrator) and on-chip DSP to decode absolute angular or linear displacement from magnet motion, supporting 4/8-point LNR or 16/32-segment PWL transfer characteristics. Its architecture includes dual ADCs for VX/VY/VZ, temperature-compensated gain control, and FIR/exponential moving average filtering with selectable latency profiles.
This variant implements Standard/Legacy Mode (BCC-308), enabling backward compatibility with prior-generation MLX9036x devices while retaining full programmability of output range, clamping levels, diagnostic thresholds, and PWM frequency (150–2000 Hz). The DMP-4 package embeds decoupling capacitance and eliminates PCB mounting requirements.

FAQ
What is the operating temperature range of the MLX90371GVS-BCC-308-RX?
The MLX90371GVS-BCC-308-RX is qualified for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements for under-hood automotive use. This range is validated across all electrical parameters including supply current, output accuracy, and latency time without derating.
Does the MLX90371GVS-BCC-308-RX require external decoupling capacitors?
No, the MLX90371GVS-BCC-308-RX in DMP-4 package integrates a 100 nF decoupling capacitor internally, eliminating the need for external ceramic capacitors. This reduces PCB area and improves reliability in vibration-prone automotive environments.
How does the MLX90371GVS-BCC-308-RX achieve stray-field immunity in Standard/Legacy Mode?
In Standard/Legacy Mode (BCC-308), the MLX90371GVS-BCC-308-RX applies proprietary signal processing algorithms to suppress interference from external magnetic fields up to 1 mT, verified per ISO11452-8 testing. This mode maintains backward compatibility while delivering robustness against adjacent motors and solenoids.
Can the MLX90371GVS-BCC-308-RX output both analog and PWM signals simultaneously?
No, the MLX90371GVS-BCC-308-RX supports either ratiometric analog voltage or PWM output per configuration - not both concurrently. Output mode is selected during programming via the I²C interface and stored in NVRAM; switching requires reprogramming.
What safety certification does the MLX90371GVS-BCC-308-RX hold?
The MLX90371GVS-BCC-308-RX is certified as an ISO26262 ASIL-B Safety Element out-of-Context (SEooC), with documented safety mechanisms including memory ECC, supply voltage monitoring, watchdog timers, and diagnostic coverage for internal signal paths - enabling integration into ASIL-B automotive subsystems.
