Product details
Overview
MLX90423GVE-ACA-230-SP from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute linear position sensing with stray field immunity up to 5 mT. It delivers SENT (SAE J2716 APR2016), PWM, or ratiometric analog output, operates from −40°C to +160°C, and is AEC-Q100 Grade 0 qualified for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90423GVE-ACA-230-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SMP-3), confirmed output protocols (SENT/PWM/analog), functional safety classification (ASIL-C for SENT/PWM), stray-field robustness (≤5 mT), and exact pin definitions per official Melexis documentation.
Technical Context
The MLX90423GVE-ACA-230-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz components, enabling absolute linear position decoding without mechanical contact. Its on-chip DSP supports programmable multi-point linearization (12–16 points) and configurable filtering.
It implements ISO 26262 SEooC with ASIL-C for SENT and PWM outputs and ASIL-B for analog output. The device uses internal 24 MHz main clock (±5% over temp/lifetime) and supports SENT frame lengths of 282/310 ticks for synchronous acquisition or asynchronous operation with 486–538 μs internal measurement period.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90422GVE-ACA-230-SP | Single-die SMP-3 variant with identical pinout, same -2xx stray-field-robust configuration, but lacks 48-bit ID and advanced diagnostics. | Lower-cost alternative where SEooC certification and full ASIL-C diagnostics are not required. | Select MLX90422GVE-ACA-230-SP only if functional safety documentation and secure sensor messaging are unnecessary. |
| TLV493DW2B6HTSA1 | Infineon 3D Hall sensor in TSSOP-20; supports I²C only, no SENT/PWM; ±1.5° accuracy; no ASIL rating. | Non-safety-critical industrial position feedback where digital bus integration outweighs automotive qualification needs. | Choose TLV493DW2B6HTSA1 only for non-automotive designs requiring I²C interface and lower cost, accepting reduced accuracy and no functional safety support. |
Compared with MLX90423GVE-ACA-230-SP, MLX90422GVE-ACA-230-SP offers identical form factor and basic sensing but omits certified safety mechanisms and unique identification, while TLV493DW2B6HTSA1 trades automotive qualification and multi-protocol output for I²C simplicity and broader industrial availability - neither is pin-compatible nor drop-in replaceable.

FAQ
What output protocols does the MLX90423GVE-ACA-230-SP support?
The MLX90423GVE-ACA-230-SP supports SENT (SAE J2716 APR2016), PWM, and ratiometric analog outputs. All three are factory-configurable via end-user programming; the -230 option code indicates pre-programmed SENT capability, reprogrammable to PWM or analog. Output selection is performed during final calibration and does not require hardware changes to the MLX90423GVE-ACA-230-SP itself.
Is the MLX90423GVE-ACA-230-SP qualified for automotive use?
Yes, the MLX90423GVE-ACA-230-SP is AEC-Q100 Grade 0 qualified (−40°C to +160°C) and certified as an ISO 26262 SEooC with ASIL-C for SENT and PWM outputs and ASIL-B for analog output. It meets stray magnetic field immunity per ISO 11452-8 up to 5 mT, making it suitable for under-hood and chassis-mounted automotive applications such as pedal and throttle position sensing.
What is the package type and pin configuration of the MLX90423GVE-ACA-230-SP?
The MLX90423GVE-ACA-230-SP uses the SMP-3 package - a PCB-less single-mold construction with three terminals: Pin 1 = VDD, Pin 2 = OUT, Pin 3 = VSS. This package integrates decoupling capacitance and is designed for direct mounting on flex substrates or molded interconnect devices, eliminating external capacitors and reducing system size.
How does the MLX90423GVE-ACA-230-SP achieve stray magnetic field immunity?
The MLX90423GVE-ACA-230-SP achieves stray-field immunity up to 5 mT through its Triaxis® Hall architecture and proprietary on-chip signal processing. The -230 option code denotes factory pre-programmed linear stray-field-robust mode, which uses differential Bx/By/Bz vector analysis and adaptive filtering to reject common-mode interference - validated per ISO 11452-8 without external shielding.
Can the MLX90423GVE-ACA-230-SP be reprogrammed after installation?
Yes, the MLX90423GVE-ACA-230-SP supports end-user programming of output mode (SENT/PWM/analog), transfer characteristic (12–16 point linearization), filtering, and diagnostics via standard SENT or PWM communication. Reprogramming requires Melexis-approved tools and protocol access; the MLX90423GVE-ACA-230-SP retains settings in NVRAM and survives power cycles without loss of configuration.
