Product details

Overview

MLX90376GGO-ABA-680-RE from Melexis is a Triaxis® Hall-based monolithic magnetic position sensor IC for absolute rotary position sensing up to 360° in stray-field immune mode. It delivers SPC (Short PWM Code) output with 1.5 μs tick time, operates from −40 °C to +160 °C, and meets AEC-Q100 Grade-0 and ISO 26262 SEooC ASIL C requirements. Used in automotive throttle and steering wheel position sensing.

For engineers reviewing the MLX90376GGO-ABA-680-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, TSSOP-16_EP dual-die package details, SPC timing compliance, stray-field immunity up to 5 mT, and ASIL C safety architecture - all confirmed for the exact -ABA-680 option in GO package.

Technical Context

The MLX90376GGO-ABA-680-RE implements Triaxis® Hall sensing of B_x, B_y, and B_z magnetic components to compute absolute angular position without mechanical contact. Its dual-die TSSOP-16_EP configuration enables redundancy and isolation (≥4 MΩ between dies), supporting ASIL C fault containment for SPC output.

It uses a programmable DSP for piecewise-linearization (up to 32 segments), configurable filtering, and on-chip diagnostics including watchdog timers and broken-wire detection. The SPC protocol operates at 1.5 μs tick time with status & communication nibble (SCN) encoding, requiring external pull-up resistors of 3–55 kΩ per specification.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90376GGO-ABA-630-RE	Same TSSOP-16_EP package and 360° stray-field immune mode, but SENT (not SPC) output with 3 μs tick time.	Requires SENT-capable ECU receiver; lacks SPC-specific diagnostics like SCN status nibble.	Select when ECU interface mandates SENT protocol or higher noise margin is needed over longer harness runs.
MLX90376GDC-ADA-680-RE	SOIC-8 single-die package, same SPC output and -680 option, but no dual-die redundancy or isolation.	Not suitable for ASIL C systems requiring hardware redundancy; lower thermal dissipation capability.	Select for cost-sensitive, non-safety-critical applications where PCB space is constrained and single-die reliability suffices.

Compared with MLX90376GGO-ABA-680-RE, the -630 variant offers SENT compatibility at the expense of SPC-specific timing and diagnostics, while the SOIC-8 -ADA-680 reduces cost and size but removes die-level isolation and ASIL C support - making the GO-package -ABA-680 uniquely suited for dual-channel safety architectures.

FAQ

What output protocol does the MLX90376GGO-ABA-680-RE support, and can it be changed after manufacturing?

The MLX90376GGO-ABA-680-RE supports only SPC (Short PWM Code) output with a fixed 1.5 μs tick time. This protocol is factory-programmed and cannot be altered by end users - the -680 option code permanently configures the IC for SPC operation. Attempting to drive it with SENT or PWM signals will result in invalid output frames. For protocol flexibility, separate order codes such as -630 (SENT) or -610 (PWM) must be selected at purchase.

Does the MLX90376GGO-ABA-680-RE meet automotive safety standards, and what ASIL level does it support?

Yes, the MLX90376GGO-ABA-680-RE is AEC-Q100 Grade-0 qualified and certified as an ISO 26262 SEooC component with ASIL C for SPC output. Its dual-die TSSOP-16_EP architecture enables hardware-level redundancy, including isolated power/ground domains and cross-die diagnostics, fulfilling fault detection and safe state requirements for steering and throttle control systems. The ASIL C rating applies specifically to the SPC output path - analog or PWM variants carry lower ASIL ratings.

What is the magnetic stray-field immunity specification for the MLX90376GGO-ABA-680-RE, and how is it validated?

The MLX90376GGO-ABA-680-RE provides stray-field immune 360° angle sensing up to 5 mT (4 kA/m) as verified per ISO 11452-8. This immunity is achieved through Triaxis® 3D Hall sensing combined with on-chip differential signal processing that rejects common-mode field interference. Validation includes full-angle accuracy testing under superimposed DC and AC magnetic fields up to 5 mT, confirming ≤1.5° total error across the entire 360° range - critical for placement near motors, solenoids, or braking systems.

How is redundancy implemented in the MLX90376GGO-ABA-680-RE, and what isolation is provided between dies?

The MLX90376GGO-ABA-680-RE implements hardware redundancy via two fully independent sensor dies in a single TSSOP-16_EP package. Each die has dedicated VDD1/VSS1/OUT1 and VDD2/VSS2/OUT2 pins, with ≥4 MΩ isolation resistance measured between VSS1 and VSS2 under ±20 V bias. This physical separation allows independent power cycling, fault injection testing, and cross-die comparison - forming the basis for ASIL C diagnostic coverage without requiring external monitoring circuitry.

What are the key timing parameters for SPC operation in the MLX90376GGO-ABA-680-RE, and how do they impact system design?

The MLX90376GGO-ABA-680-RE operates SPC with a 1.5 μs tick time, 400 μs typical refresh period (Low Power Mode), and 4.2 ms maximum startup time. These values define minimum ECU sampling intervals, required pull-up resistor range (3–55 kΩ), and synchronization window for trigger pulse reception. Designers must ensure host microcontroller input capture resolution supports 1.5 μs edges and that PCB layout minimizes capacitance on OUT1/OUT2 traces to maintain signal integrity within the SPC timing budget.
