Product details
Overview
MLX90374GDC-ABB-300-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers dual-output signals (PWM or SENT + programmable switch), operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, and supports stray-field immune configurations. It is used in automotive throttle, pedal, and steering wheel position sensing where robust non-contact measurement is required.
For engineers reviewing the MLX90374GDC-ABB-300-SP datasheet, pinout, applications, or equivalent options, key selection considerations include its SOIC-8 package, dual-output flexibility (PWM/SENT), AEC-Q100 qualification, programmable transfer characteristic, and legacy-mode (-300) angular/linear position decoding capability.
Technical Context
The MLX90374GDC-ABB-300-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, an analog-to-digital signal conditioner, and a DSP for real-time angle computation. Its -300 option code configures it for legacy angular/linear position mode with standard magnetic circuit requirements-not stray-field immune.
It supports two primary output modes: dual PWM (redundant or independent) or SENT (SAE J2716 APR2016 compliant) plus a programmable switch. Timing is governed by a 24 MHz ±5% main clock; SENT frame timing defaults to 3 µs tick time with synchronous acquisition and configurable angles per frame (1 or 2).

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90374GDC-ABC-300-RE | ABC revision replaces ABB; adds enhanced diagnostics, safe startup, and updated memory programming flow | Same -300 angular/linear function but improved diagnostic coverage and startup behavior | Select ABC-300 for new designs requiring full ISO26262 toolchain support and long-term availability |
| MLX90363GDC-ABB-100-RE | Rotary stray-field immune variant (-100); different magnetic configuration and calibration profile | Optimized for high-stray-field environments (e.g., near motors), not interchangeable with -300 mode | Choose only if stray-field immunity is mandatory and magnetic circuit is redesigned accordingly |
Compared with MLX90374GDC-ABB-300-SP, the ABC-300 offers verified safety mechanisms and lifecycle support, while the MLX90363-100 targets distinct magnetic environments-neither is pin-compatible nor functionally drop-in; both require validation against the specific mechanical and EMI context.

FAQ
What is the operating temperature range of the MLX90374GDC-ABB-300-SP?
The MLX90374GDC-ABB-300-SP is rated for continuous operation from -40°C to +160°C ambient temperature. This range is validated per AEC-Q100 Grade 0 and supports placement in demanding under-hood locations such as throttle bodies and transmission housings. The device maintains specified accuracy and timing performance across this full range when powered within its 4.5–5.5 V supply window.
Does the MLX90374GDC-ABB-300-SP support SENT protocol, and which version?
Yes, the MLX90374GDC-ABB-300-SP supports Single Edge Nibble Transmission (SENT) per SAE J2716 APR2016. It delivers enhanced messages with CRC, error codes, and user-defined data fields. Frame timing defaults to 3 µs tick time with synchronous acquisition, and configuration supports one or two angle values per frame-both modes are fully implemented in the -300 legacy application setting.
What does the "-300" option code signify in MLX90374GDC-ABB-300-SP?
The "-300" option code configures the MLX90374GDC-ABB-300-SP for legacy angular or linear position sensing mode-distinct from stray-field immune variants (-100/-200). It uses standard magnetic circuit topologies and is optimized for applications like throttle and pedal position where external stray fields are controlled. This mode supports full programmability of transfer characteristics and diagnostics.
Is the MLX90374GDC-ABB-300-SP pin-compatible with newer ABC revision devices?
No, the MLX90374GDC-ABB-300-SP is not pin-compatible with ABC revision devices in terms of programming interface or diagnostic behavior-even though physical pinout and package are identical. The ABC revision introduces updated memory access protocols, enhanced watchdog logic, and safe startup sequences that require firmware and system-level validation. Migration requires full requalification.
Can the MLX90374GDC-ABB-300-SP operate with a 12 V battery supply?
Yes, the MLX90374GDC-ABB-300-SP supports battery-supplied operation (6–18 V) via its integrated voltage regulator. When configured for battery mode (using WARM_ACT_HIGH parameter), it enables overvoltage protection at 21.5–24.5 V and undervoltage lockout at 3.9–4.25 V. Internal regulation maintains stable 3.3 V analog and 1.85 V digital supplies regardless of input variation.
