Product details
Overview
MLX90374GDC-ABC-100-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute angular rotary sensing with stray-field immunity. It delivers dual PWM output, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, and supports AEC-Q100 qualification for automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90374GDC-ABC-100-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOIC-8), confirmed pin functions, validated stray-field immune angular mode operation, real-world timing specs (e.g., 6.6 ms PWM startup), and direct alternative part comparisons for automotive sensor design.
Technical Context
The MLX90374GDC-ABC-100-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling robust absolute angle decoding without mechanical contact. Its on-chip DSP implements programmable piecewise linear (PWL) transfer characteristics-up to 32 points-and supports dual-output configurations including redundant PWM or SENT plus switch.
This variant uses the ABC chip revision in SOIC-8 (DC) package with option code -100, configuring it specifically for angular rotary stray-field immune operation. It includes built-in diagnostics (IWD/AWD timeouts at 20 ms), failsafe state duration of 9.8–11.9 ms, and safe startup time of 11.2–12.4 ms-exclusive to ABC revision firmware.

Applications
| Throttle Position Sensing | Steering Wheel Angle Sensing |
|---|---|
Use Scenario: Real-time detection of accelerator pedal rotation in gasoline/diesel powertrains with high EMC stress. IC Role / Device Role / Timing Role: Absolute angular position processor delivering two synchronized PWM signals for ECU redundancy validation. Use Value: Stray-field immunity prevents misreads from nearby solenoids; 6.6 ms PWM startup meets ASIL-B timing constraints. |
Use Scenario: Contactless measurement of driver steering input across full 720° rotation in EPS systems. IC Role / Device Role / Timing Role: Primary angular sensor feeding torque/angle fusion algorithms with dual PWM outputs for cross-checking. Use Value: On-chip 32-point PWL correction eliminates calibration drift over temperature; ASIL-C compliance reduces system-level safety analysis burden. |

Use Scenario: Suspension height feedback in adaptive air ride systems requiring long-term stability and field resilience. IC Role / Device Role / Timing Role: Stray-field immune angular sensor mounted near suspension actuators and motors. Use Value: Immunity to stray fields from adjacent 12V motors avoids recalibration; failsafe state duration (9.8–11.9 ms) aligns with chassis controller watchdog windows. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90375GDC-ABC-100-RE | Same SOIC-8 package and -100 stray-field immune configuration, but adds SENT+PWM dual output instead of dual PWM | Required where host ECU needs digital SENT protocol alongside analog-compatible PWM for legacy compatibility | Select when SENT message payload (e.g., diagnostics, ID, temperature) is needed in addition to PWM redundancy |
| TLV493DW2B6HTSA1 | 3D Hall sensor IC with I²C interface only; no integrated PWM/SENT drivers or ASIL-C certification | Used in non-safety-critical industrial encoders or consumer devices where cost and size outweigh functional safety needs | Choose only for cost-sensitive, non-automotive designs lacking ASIL requirements and PWM interface demand |
Compared with MLX90374GDC-ABC-100-RE, the MLX90375 offers enhanced digital flexibility at the expense of pure PWM simplicity, while the TLV493D lacks both safety certification and native PWM output-making MLX90374GDC-ABC-100-RE the sole choice for ASIL-C-compliant dual-PWM automotive angular sensing.

FAQ
What is the primary magnetic sensing architecture used in the MLX90374GDC-ABC-100-RE?
The MLX90374GDC-ABC-100-RE employs Melexis' proprietary Triaxis® Hall technology, which simultaneously measures all three orthogonal components (Bx, By, Bz) of the applied magnetic flux density. This 3D capability enables precise absolute angular position calculation without mechanical contact and provides inherent immunity to stray magnetic fields-especially critical in automotive engine bays where solenoids and motors generate interference. The architecture is implemented on a single die within the SOIC-8 package.
How does the -100 option code affect the functionality of the MLX90374GDC-ABC-100-RE?
The -100 option code configures the MLX90374GDC-ABC-100-RE specifically for Angular Rotary Strayfield Immune operation. This mode applies optimized internal calibration and filtering to reject external magnetic interference orthogonal to the intended sensing axis, achieving <±0.5° angular accuracy even under ±10 mT stray fields. It also enables the safe startup sequence (TSafeStup = 11.2–12.4 ms) and activates the full ASIL-C diagnostic coverage defined in the safety manual.
Does the MLX90374GDC-ABC-100-RE support SENT output, or is it PWM-only?
The MLX90374GDC-ABC-100-RE supports dual PWM output by default in its factory configuration. While the underlying MLX90374 silicon can be programmed for SENT+switch mode, the -100 option code in the DC (SOIC-8) package is specified and validated exclusively for dual PWM operation per Melexis documentation. SENT functionality requires different option codes (e.g., -300) and is not enabled or guaranteed for MLX90374GDC-ABC-100-RE.
What is the significance of the ABC revision in MLX90374GDC-ABC-100-RE?
The ABC revision in MLX90374GDC-ABC-100-RE denotes the current preferred silicon version for new designs, incorporating enhancements over the legacy ABB revision-including safe startup diagnostics, improved stray-field rejection algorithms, and extended functional safety coverage. Only the ABC revision supports the TSafeStup parameter (11.2–12.4 ms) and full ISO26262 ASIL-C SEooC compliance. Melexis explicitly states ABB is "not recommended for new designs."
Can the MLX90374GDC-ABC-100-RE operate directly from a 12 V battery supply?
Yes, the MLX90374GDC-ABC-100-RE supports battery-supplied operation from 6 V to 18 V using its internal voltage regulation architecture. When configured for battery mode (via WARM_ACT_HIGH parameter), it activates overvoltage protection thresholds at 21.5–24.5 V and undervoltage detection at 3.75–4.25 V. Supply current remains within 8.0–10.5 mA across the full temperature range, enabling direct connection to automotive battery rails without external regulators in many implementations.
