Product details

Overview

MLX90372GVS-ACE-101-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary position sensing in stray-field-immune configurations. It delivers SENT 3µs output, operates from -40°C to +160°C, supports programmable linear transfer characteristic (up to 32-point PWL), and features ISO26262 ASIL-C Safety Element out of Context compliance. Used in automotive throttle and steering wheel position sensing.

For engineers reviewing the MLX90372GVS-ACE-101-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4 Pinout-B), confirmed SENT timing (3µs tick, 960 µs frame), stray-field immunity specification (-100 code), and functional safety architecture per ISO26262.

Technical Context

The MLX90372GVS-ACE-101-SP implements a Triaxis® Hall front end sensitive to B_x, B_y, and B_z magnetic field components, enabling robust absolute angle decoding without mechanical contact. Its on-chip DSP performs real-time signal conditioning, filtering, and piecewise linear (PWL) interpolation with up to 32 points.

It operates in Continuous Asynchronous Acquisition Mode by default (T_angleMeas = 588 µs), outputs SENT frames compliant with SAE J2716 APR2016, and uses internal regulated V_DEC = 3.3 V ±0.1 V. The DMP-4 package integrates built-in decoupling capacitors and supports NTC or analog/digital gateway via the Input pin in Pinout-B configuration.

Equivalent & Alternatives

The following parts are listed as comparable options for similar magnetic position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90372GVS-ACE-100-SP	Same DMP-4 Pinout-B package and -100 stray-field immune mode, but uses capacitor configuration #1 (STD1 1.27 trim) instead of #2 (STD1 2.54)	Identical functional scope; differs only in mechanical mounting pitch and internal capacitor layout	Select ACE-100 for legacy board compatibility with 1.27 mm pitch; ACE-101 requires 2.54 mm pad spacing.
MLX90372GVS-ACE-103-SP	Same DMP-4 Pinout-B and -100 mode, but uses STD2 2.54 trim & form (different internal capacitor arrangement and marking)	No change in electrical performance or magnetic behavior; mechanical variant optimized for higher-volume automated assembly	ACE-103 offers improved thermal dissipation margin per section 18.11; preferred for high-ambient industrial variants.

Compared with MLX90372GVS-ACE-101-SP, ACE-100 shares identical electrical specs and stray-field immunity but requires tighter 1.27 mm PCB pitch, while ACE-103 maintains the same 2.54 mm pitch but improves thermal resistance by 8°C/W - making it suitable for sustained 160°C ambient operation where ACE-101 may require derating.

FAQ

What output protocol does the MLX90372GVS-ACE-101-SP support?

The MLX90372GVS-ACE-101-SP supports SENT 3µs mode per SAE J2716 APR2016 and configurable PWM output. SENT frames include CRC, diagnostic flags, and user-defined data fields. PWM mode is selectable via programming but not active by default - SENT is factory-configured for ACE-101. Output drive strength supports 5–18 V pull-up resistors with 25 mA short-circuit protection.

Is the MLX90372GVS-ACE-101-SP pin-compatible with earlier MLX90372 revisions?

Yes - the MLX90372GVS-ACE-101-SP uses DMP-4 Pinout-B, which is pin-compatible with prior Triaxis® generations using the same pinout. Pin 1 is OUT, Pin 2 is VSS, Pin 3 is VDD, and Pin 4 is Input. However, ACE-101 uses capacitor configuration #2 (STD1 2.54), so PCB land patterns must match that specific trim & form; it is not compatible with ACE-100's STD1 1.27 layout.

Does the MLX90372GVS-ACE-101-SP require external decoupling capacitors?

No - the MLX90372GVS-ACE-101-SP in DMP-4 package includes built-in decoupling capacitors per section 15.3 of the datasheet. This eliminates the need for external VDD/VSS bypass caps, reducing BOM count and PCB area. The internal capacitors are optimized for SENT 3µs timing stability and meet EMI requirements without additional filtering components.

What is the meaning of "-101" in the MLX90372GVS-ACE-101-SP part number?

The "-101" suffix in MLX90372GVS-ACE-101-SP breaks down as: "1" = Angular Rotary Strayfield Immune (-100 code), "0" = SENT 3µs mode, "1" = Capacitor configuration #2 (STD1 2.54 trim & form). This distinguishes it from ACE-100 (STD1 1.27) and ACE-103 (STD2 2.54), all sharing the same magnetic and safety specifications but differing in mechanical packaging.

How does the MLX90372GVS-ACE-101-SP achieve stray-field immunity?

The MLX90372GVS-ACE-101-SP achieves stray-field immunity through hardware-level differential sensing of orthogonal magnetic components (B_x, B_y, B_z) combined with proprietary on-die signal processing that rejects common-mode interference. This is specifically enabled in the -100 option code configuration, validated per section 8.1 of the datasheet for operation in fields up to ±10 mT orthogonal to the main sensing axis - critical for throttle and pedal applications near high-current actuators.
