FAQ
What output protocol does the MLX90377GVS-ADB-330-RE support?
The MLX90377GVS-ADB-330-RE is factory-configured exclusively for SENT output per SAE J2716 APR2016 with 3 μs tick time. It does not support analog, PWM, or SPC modes - output protocol is fixed at manufacture and cannot be reprogrammed in the field. This ensures deterministic timing and ASIL-C compliance without runtime configuration risks.
Is the MLX90377GVS-ADB-330-RE pin-compatible with other MLX90377 variants?
No - the MLX90377GVS-ADB-330-RE uses the DMP-4 package (4-pin), while SOIC-8 and TSSOP-16 variants have different pin counts and layouts. DMP-4 shares pinout with prior Triaxis® DMP-4 generations but is not mechanically or electrically compatible with SOIC-8 or TSSOP-16 footprints. PCB redesign is required for substitution.
Does the MLX90377GVS-ADB-330-RE require external decoupling capacitors?
No - the DMP-4 package integrates internal decoupling capacitance, eliminating the need for external VDEC capacitors. This simplifies layout, reduces bill-of-materials, and enhances reliability in high-vibration environments where capacitor solder joint fatigue is a concern. The device meets EMC requirements without external caps.
What is the functional safety qualification status of the MLX90377GVS-ADB-330-RE?
The MLX90377GVS-ADB-330-RE is certified as a Safety Element out of Context (SEooC) per ISO 26262, achieving ASIL-C for SENT output mode and ASIL-B for analog mode (though analog is disabled in this variant). Full safety manual, FMEDA, and diagnostic coverage reports are available from Melexis for integration into ASIL-D systems.
Can the MLX90377GVS-ADB-330-RE be used in linear position sensing applications?
Yes - the MLX90377GVS-ADB-330-RE supports both absolute rotary (0–360°) and linear displacement sensing using appropriate magnet configurations. Its Triaxis® architecture measures Bx, By, and Bz simultaneously, enabling accurate position decoding from moving magnets in either geometry - validated in applications like float-level and ride height sensors.
