Product details
Overview
MLX90372GVS-ACE-357-RX from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers SENT or PWM output, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, AEC-Q100 qualification, and supports programmable transfer characteristics (up to 32-point PWL) in a PCB-less DMP-4 package. Used in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90372GVS-ACE-357-RX datasheet, pinout, applications, or equivalent options, key selection criteria include DMP-4 package form factor, SENT 3µs mode with STD3 2.00mm trim & form, stray-field immune legacy-mode operation, and robustness against magnetic interference in high-temperature engine bay environments.
Technical Context
The MLX90372GVS-ACE-357-RX implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling absolute angle decoding from 0° to 360° or linear displacement without physical contact. Its on-chip DSP performs real-time signal conditioning, filtering, and piecewise linear (PWL) interpolation using up to 32 user-defined points.
It supports SENT SAE J2716 APR2016 compliant frames with Secure Sensor format, including error codes and user-defined data fields, and can be reconfigured via EEPROM to output PWM with programmable duty cycle. The DMP-4 package (Pinout-B) integrates built-in decoupling capacitors and uses Input pin as NTC or analog/digital gateway.

FAQ
What output protocols does the MLX90372GVS-ACE-357-RX support?
The MLX90372GVS-ACE-357-RX supports SENT (SAE J2716 APR2016) and PWM output modes, both configurable via EEPROM programming. SENT operates in 3µs tick mode with Secure Sensor format including CRC and diagnostic fields; PWM offers programmable duty cycle and frequency. The device ships pre-configured for SENT in the -357 option code.
What is the significance of the "ACE-357" option code in MLX90372GVS-ACE-357-RX?
The ACE-357 option code specifies: ACE = standard chip revision; 3 = legacy/angular-linear position mode; 5 = SENT 3µs mode; 7 = STD3 2.00 mm trim & form configuration. This defines the MLX90372GVS-ACE-357-RX as a DMP-4 Pinout-B device with integrated capacitors, optimized for compact high-temperature installations.
Does the MLX90372GVS-ACE-357-RX require external decoupling capacitors?
No - the MLX90372GVS-ACE-357-RX uses DMP-4 Pinout-B with built-in decoupling capacitors per Section 15.3 of the datasheet. External capacitors are not required, though layout best practices (short traces, low-inductance ground) remain essential for EMC robustness.
How does the MLX90372GVS-ACE-357-RX achieve stray-field immunity in legacy mode?
The MLX90372GVS-ACE-357-RX achieves stray-field immunity in -300 legacy mode through on-chip differential signal processing of Triaxis® Hall measurements, combined with adaptive filtering and magnetic offset cancellation algorithms. This allows operation in environments with up to ±1 T external DC/AC magnetic fields without accuracy degradation.
Is the MLX90372GVS-ACE-357-RX qualified for automotive use?
Yes - the MLX90372GVS-ACE-357-RX is AEC-Q100 Grade 0 qualified (-40°C to +160°C) and certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC), with integrated diagnostics including IWD, AWD, memory ECC, and configurable fault response states.
