Product details
Overview
MLX90372GVS-ADE-311-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers SENT 3µs output with built-in capacitors in DMP-4 package, operates from -40°C to +160°C, supports stray-field immunity, and is ISO26262 ASIL-C Safety Element out of Context certified for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90372GVS-ADE-311-SP datasheet, pinout, applications, or equivalent options, this page provides verified pin definitions, SENT timing compliance (SAE J2716 APR2016), DMP-4 STD1 2.54 trim-and-form configuration, ADE revision-specific Ron (50–100 Ω push-pull), and functional safety architecture details.
Technical Context
The MLX90372GVS-ADE-311-SP implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling robust absolute angle decoding without mechanical contact. Its on-chip DSP performs real-time signal conditioning, piecewise linear (PWL) transfer function mapping (up to 32 points), and SENT frame encoding with CRC and diagnostic fields.
It operates in continuous asynchronous acquisition mode (TangleMeas = 528–588 µs) for SENT 3µs output, uses internal 24 MHz main clock (±5% thermal/lifetime drift), and integrates dual-stage watchdogs (IWD/AWD, 20 ms timeout) plus analog/digital diagnostics with configurable cycle times (DCTANA = 34 µs, DCTDIG = 20 ms).

Does the MLX90372GVS-ADE-311-SP support PWM output in addition to SENT?
Yes, the MLX90372GVS-ADE-311-SP supports both SENT 3µs and PWM output modes, selectable via end-user programming. In PWM mode, it delivers a duty cycle proportional to position with 12-bit resolution, configurable update rate, and programmable dead time. The output remains push-pull capable with Ron = 50–100 Ω, ensuring compatibility with standard automotive PWM receivers.
What does the "ADE-311" option code signify for the MLX90372GVS-ADE-311-SP?
The "ADE-311" option code identifies the MLX90372GVS-ADE-311-SP as a DMP-4 packaged device (VS), ADE chip revision (low-emission variant), legacy/angular-linear application configuration (-300), Pinout-B (supporting Input pin for NTC/gateway), and STD1 2.54 trim-and-form package outline (section 18.10). This configuration includes built-in capacitors and optimized EMC layout for high-noise automotive environments.
How is functional safety implemented in the MLX90372GVS-ADE-311-SP?
The MLX90372GVS-ADE-311-SP implements ISO26262 ASIL-C SEooC through hardware-level safety mechanisms: dual independent watchdogs (IWD/AWD), memory ECC for NVRAM and RAM, startup self-tests, analog/digital diagnostic cycles (DCTANA/DCTDIG), and CRC-protected SENT frames. These features are documented in the Melexis Safety Manual and enable reuse in ASIL-B or ASIL-C systems with proper system-level integration.
Can the MLX90372GVS-ADE-311-SP be used for linear position sensing?
Yes, the MLX90372GVS-ADE-311-SP supports both absolute rotary (0–360°) and absolute linear position sensing using the same Triaxis® Hall front end and programmable transfer characteristic. Linear applications require appropriate magnet geometry (e.g., back-biased linear array) and calibration via the 32-point PWL function. Stray-field immunity modes (-100, -200) are available to suppress interference in linear configurations.
