Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-ABD-357-RE | Single-die architecture; no dual-die redundancy; lower diagnostic coverage | Lacks ASIL-C SEooC qualification; limited to ASIL-B system integration | Select when cost sensitivity outweighs functional safety requirements and stray-field immunity remains sufficient |
| AMS AS5055A-BQFT | 14-bit SPI/I²C output; no SENT/PWM native support; requires external protocol translation | Higher resolution but lacks automotive-grade SENT interface and integrated diagnostics | Choose for non-automotive industrial encoders where digital bus flexibility is prioritized over drop-in SENT compatibility |
Compared with MLX90372GVS-ACE-357-RE, MLX90371GVS-ABD-357-RE reduces BOM cost but increases system-level safety validation effort, while AMS AS5055A-BQFT offers higher resolution yet requires additional interface logic and fails to meet AEC-Q100 Grade 0 thermal specs.

What output protocols does the MLX90372GVS-ACE-357-RE support?
The MLX90372GVS-ACE-357-RE supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, selectable via end-user programming. SENT frames include 12-bit position data, CRC, and diagnostic status bits; PWM offers 10%–90% duty cycle scaling over full range. No hardware change is needed to switch between them - only reprogramming of the device's configuration memory.
What is the package type and pin configuration of MLX90372GVS-ACE-357-RE?
The MLX90372GVS-ACE-357-RE uses the DMP-4 (Dual Mould Package) with Pinout-B configuration: Pin 1 = OUT, Pin 2 = VSS, Pin 3 = VDD, Pin 4 = Input (NTC/gateway). It implements STD3 2.00 mm trim/form and integrates decoupling capacitors - eliminating external bypass components and reducing PCB footprint.
Does MLX90372GVS-ACE-357-RE meet automotive functional safety standards?
Yes, the MLX90372GVS-ACE-357-RE is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC) and AEC-Q100 Grade 0 qualified. Its safety mechanisms include dual watchdog timers (IWD/AWD), memory ECC, and diagnostic cycle monitoring - all documented in the official Melexis Safety Manual for MLX90372.
How is stray magnetic field immunity achieved in MLX90372GVS-ACE-357-RE?
The MLX90372GVS-ACE-357-RE achieves stray-field immunity through its Triaxis® Hall architecture and differential front-end design, combined with factory-trimmed compensation algorithms. In ACE-3xx configurations (including ACE-357), it operates in Legacy Mode with validated rejection of orthogonal interfering fields up to ±100 mT, as specified in Section 8.4 of the datasheet.
Can MLX90372GVS-ACE-357-RE be programmed for custom transfer characteristics?
Yes, the MLX90372GVS-ACE-357-RE supports user-programmable transfer characteristics using up to 32-piece piecewise linear (PWL) breakpoints. This is configured via the MLX90372's EEPROM memory using Melexis' PTM software and compatible programming tool - enabling precise linearization for specific magnet geometries and mechanical tolerances.
