Product details
Overview
MLX90374GDC-ABC-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 PWM or SENT + programmable switch signals, supports -40°C to +160°C operation, features ISO26262 ASIL-C safety compliance, and enables stray-field-immune non-contact sensing in automotive throttle, pedal, and steering applications.
For engineers reviewing the MLX90374GDC-ABC-300-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOIC-8), confirmed dual-output timing modes (PWM/SENT), validated AEC-Q100 qualification, exact pin functions per official pin definition, and two technically documented alternative parts with functional and application-level distinctions.
Technical Context
The MLX90374GDC-ABC-300-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, an analog-to-digital signal conditioner, a DSP for advanced angle decoding, and a dual-output driver stage. Its architecture supports both continuous asynchronous acquisition (for PWM and SENT without pause) and synchronous acquisition (for SENT with pause), with configurable frame lengths and filtering options including FIR11 and FIR1111.
This variant uses the ABC chip revision in SOIC-8 (DC) package with option code -300, indicating legacy/angular/linear position mode - not stray-field immune - and default 3µs SENT tick time. It operates from 4.5 V to 5.5 V (regulated) or 6–18 V (battery), with supply current of 8.0–10.5 mA and startup time of ≤12.4 ms under safe startup mode.

FAQ
What is the package type and pin count of the MLX90374GDC-ABC-300-SP?
The MLX90374GDC-ABC-300-SP uses the SOIC-8 surface-mount package (Package Code DC) with 8 pins. Pin 1 is VDD, Pins 5 and 3 are OUT1 and OUT2, Pins 6 and 8 are digital and analog ground, Pin 7 is VDEC, and Pins 2 and 4 (Input and Test) are internally grounded and must be connected to PCB ground per datasheet Section 3.1.
Does the MLX90374GDC-ABC-300-SP support both PWM and SENT outputs simultaneously?
No - the MLX90374GDC-ABC-300-SP supports either dual PWM outputs or a SENT + programmable switch combination, selected during configuration. In SENT mode, OUT1 carries the SENT message and OUT2 functions as a configurable switch; in PWM mode, both outputs deliver independent or redundant PWM signals with selectable duty-cycle ranges and error reporting.
What does the "-300" option code signify in MLX90374GDC-ABC-300-SP?
The "-300" option code indicates Standard/Legacy mode - supporting both angular rotary and linear position applications without stray-field immunity. This differs from -100 (rotary stray-field immune) and -200 (linear stray-field immune). The MLX90374GDC-ABC-300-SP is calibrated for general-purpose position decoding with programmable PWL transfer characteristics.
Is the MLX90374GDC-ABC-300-SP certified for automotive safety standards?
Yes - the MLX90374GDC-ABC-300-SP is ISO26262 ASIL-C Safety Element out of Context (SEooC) and AEC-Q100 Grade 0 qualified (-40°C to +160°C). It includes built-in diagnostics such as watchdog timers (IWD/AWD), memory ECC, and configurable error reporting, enabling its use in ASIL-B or ASIL-C systems when integrated with appropriate system-level safety mechanisms.
Can the MLX90374GDC-ABC-300-SP operate directly from a 12 V automotive battery?
Yes - the MLX90374GDC-ABC-300-SP supports battery-mode operation from 6 V to 18 V (per Table 7), with internal regulation generating stable 3.3 V analog and 1.85 V digital supplies. It includes overvoltage protection triggering at 21.5–24.5 V and undervoltage lockout at 3.75–4.25 V, ensuring robust behavior during cranking and load-dump transients.
