Product details

Overview

MLX90365LGO-ACE-000-RE from Melexis is an AEC-Q100 qualified Triaxis® Hall-based absolute rotary and linear position sensor IC in TSSOP-16 package, operating from −40 °C to +150 °C, delivering 12-bit analog or PWM output with programmable transfer characteristic, thermal offset correction, and integrated diagnostics including open/short detection and over-voltage protection - deployed in automotive pedal, steering, and throttle position sensing.

For engineers reviewing the MLX90365LGO-ACE-000-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, exact pin functions for dual-die TSSOP-16 configuration, real-world accuracy specs (±0.3° angular error at 25 °C), diagnostic behavior under broken VDD/VSS conditions, and validated alternatives for redundant position sensing designs.

Technical Context

The MLX90365LGO-ACE-000-RE implements a dual-die architecture in TSSOP-16 with independent signal chains for full hardware redundancy, each die integrating Triaxis® Hall sensing of BX, BY, and BZ magnetic components, a 16-bit RISC microcontroller running at 10 MHz (2.5 MIPS), 128 B EEPROM, and DSP-based angle computation using CoRDiC transformation. It supports ratiometric analog output (0–100% VDD) or programmable PWM (100–1000 Hz) with 12-bit resolution and ±0.025% DC/LSB resolution.

Its thermal offset correction (enabled by ACE option code) actively compensates for temperature-induced drift in the DSP input stage (±90 LSB₁₅ max for L-grade), while on-chip diagnostics monitor supply rails (MT4V/MT7V thresholds), output saturation, and magnetic field strength - all configurable via EEPROM programming without external components.

Key Specifications

Pinout & Package

TSSOP-16 package with dual-die redundancy: two independent sensor channels (Die1 and Die2), each with dedicated VDD, VSS, and OUT pins; unused test pins (Test 01, Test 02, etc.) must be connected to ground per Melexis EMC recommendation.

Pin/Terminal	Circuit Role	Design Meaning
1, 11	VDD1 / VDD2	Independent power supply inputs for Die1 and Die2 - enables fault-isolated power domains.
2, 10	VSS1 / VSS2	Separate ground returns per die - prevents shared-impedance coupling during fault conditions.
6, 15	OUT2 / OUT1	Dual independent outputs - supports cross-checking or voting logic in ASIL-C systems.
4, 12, 13, 14, 16	Test 01 / Test 02 / Test 21 / Not Used1 / Test 11	Factory test points - require grounding in production layout to suppress radiated emissions.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90365LDC-ACD-000-RE	SOIC-8 single-die variant, no thermal offset correction (ACD vs ACE), lower pin count, no redundancy.	Suitable for cost-sensitive non-redundant applications like HVAC flap control where ASIL-B is not required.	Select when system-level redundancy is implemented externally or functional safety level is ASIL-A.
MLX90375ELW-ABF-000-SP	Next-generation Triaxis® sensor with 14-bit resolution, extended 0–100 °C industrial temp range, SPI interface, and enhanced EMC immunity.	Targets industrial servo drives and robotics requiring higher resolution and digital interface instead of analog/PWM.	Choose for new designs needing future-proofing, SPI configurability, or tighter angular accuracy (<±0.1°).

Compared with MLX90365LGO-ACE-000-RE, the SOIC-8 ACD variant trades dual-die redundancy and thermal correction for lower cost and smaller footprint, while the MLX90375 offers higher resolution and digital interface at the expense of analog/PWM compatibility and automotive qualification.

FAQ

What is the primary function of the MLX90365LGO-ACE-000-RE in automotive systems?

The MLX90365LGO-ACE-000-RE serves as an AEC-Q100 qualified absolute position sensor that decodes rotary or linear magnet motion into precise analog or PWM output signals. Its dual-die TSSOP-16 configuration enables hardware redundancy for safety-critical applications such as electronic throttle control and electric power steering, where failure detection and functional safety compliance are mandatory. The MLX90365LGO-ACE-000-RE integrates diagnostics, thermal offset correction, and programmable transfer characteristics to maintain accuracy across harsh under-hood environments.

How does the ACE option code differentiate MLX90365LGO-ACE-000-RE from other MLX90365 variants?

The ACE option code in MLX90365LGO-ACE-000-RE specifies inclusion of thermal output offset correction firmware and factory calibration for the L-grade (−40 °C to +150 °C) temperature range. This feature actively compensates for temperature-induced zero-point drift in the DSP input stage, reducing angular error contribution from ±90 LSB₁₅ to under ±30 LSB₁₅. Unlike ACD variants, ACE versions undergo additional characterization and EEPROM programming to enable this correction, making them mandatory for ASIL-B/C applications where thermal stability is critical.

Can MLX90365LGO-ACE-000-RE operate with standard 5 V automotive supplies?

Yes, MLX90365LGO-ACE-000-RE operates across a nominal supply range of 4.5 V to 5.5 V with ratiometric analog output scaling directly to VDD, ensuring consistent signal interpretation despite battery voltage fluctuations. It also features robust protection: over-voltage tolerance up to +24 V (absolute max), reverse voltage protection to −12 V, and under-voltage detection at 3.8–4.2 V (MT4V threshold). These specifications allow direct integration into 5 V power domains common in body control modules and powertrain ECUs without external regulation.

What diagnostic capabilities does MLX90365LGO-ACE-000-RE provide for functional safety compliance?

MLX90365LGO-ACE-000-RE provides comprehensive on-chip diagnostics including open/short detection on the output pin, broken VDD/VSS monitoring (with BVDDPD ≤0.5% VDD and BVSSPU ≥99.5% VDD thresholds), over-voltage and under-voltage detection, and magnetic field strength validation. Diagnostic modes are configurable via EEPROM (DIAG mode/level parameters), and status is reported through dedicated diagnostic output levels. These features support ASIL-B decomposition per ISO 26262 and eliminate the need for external watchdog circuits or discrete fault monitors in the signal path.

Is MLX90365LGO-ACE-000-RE pin-compatible with earlier MLX90365 revisions?

MLX90365LGO-ACE-000-RE uses the TSSOP-16 package with defined pin assignments for dual-die operation (VDD1/VDD2, VSS1/VSS2, OUT1/OUT2), and is pin-compatible with all other GO-package MLX90365 variants (e.g., MLX90365LGO-ACD-000-RE). However, pin functionality differs from SOIC-8 (DC) variants due to the doubled signal set - it is not pin-compatible with DC packages. Layout reuse requires matching the TSSOP-16 footprint and grounding all test pins as specified in Melexis Application Note AN-012.
