Product details
Overview
MLX90373KVS-ABA-303-SP from Melexis is a Triaxis® position processor IC for absolute linear and angular position sensing using 3-axis Hall technology. It delivers PSI5 v1.3/v2.1 output, supports stray-field immune operation up to 5 mT, achieves ±0.85° total angle drift over -40°C to +125°C, and operates in DMP-4 package with dual-ground terminals. It is used in throttle and pedal position sensing where robustness against EMI and magnetic interference is critical.
For engineers reviewing the MLX90373KVS-ABA-303-SP datasheet, pinout, applications, or equivalent options, key selection criteria include PSI5 timing compliance (300–500 µs cycle), DMP-4 mechanical form factor, -30x option code behavior (Legacy/Linear-Angular mode), AEC-Q100 Grade 0 qualification, and ISO 26262 SEooC ASIL-C functional safety support.
Technical Context
The MLX90373KVS-ABA-303-SP implements Triaxis® Hall sensing of BX, BY, and BZ components to compute absolute position via on-chip DSP. Its -30x option code configures it for Legacy/Linear-Angular mode, requiring ≥11 mT useful magnetic field norm (BNorm) and supporting multi-point linearization (4/8/17/32 points).
It uses a 2-wire PSI5 interface over VDD/PSI5-OUT and VSS, with programmable diagnostics, 48-bit ID, and integrated watchdogs (IWD/AWD). The DMP-4 package features two ground pins (Pin 1 and Pin 4), supply/PSI5-OUT on Pin 2, and one NC terminal - optimized for PCB-less mounting in space-constrained automotive sensors.
Key Specifications

Pinout & Package
DMP-4 is a dual-mold, PCB-less package with 4 terminals and no internal substrate. It enables direct solder-mounting onto flex or rigid boards with minimal footprint and thermal mass. Pins are arranged in single row with 2.54 mm pitch (STD2 trim-and-form).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground return path; must be connected to system ground for EMC compliance and stable bias reference. |
| 2 | VDD / PSI5-OUT | Supply input and bidirectional PSI5 data line; carries modulated current signal during active communication cycles. |
| 3 | N.C. | No internal connection; must remain unconnected per datasheet to avoid parasitic coupling or latch-up risk. |
| 4 | VSS | Second ground terminal; improves current return symmetry and reduces ground loop impedance in noisy environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90373KGO-ABA-303-RE | TSSOP-16 dual-die package with full redundancy; isolation resistance >4 MΩ between dice; higher quiescent current (2×10.5 mA typical). | Required for ASIL-D systems needing hardware redundancy; unsuitable for space-constrained DMP-4 footprints. | Select when functional safety architecture mandates die-level redundancy and board area permits TSSOP-16. |
| MLX90371KDC-ABA-303-RE | SOIC-8 single-die variant; same -30x functionality but different pinout (8-pin vs DMP-4's 4-terminal layout); lacks DMP-4's trim-and-form leads. | Better suited for traditional PCB assembly with through-hole or gull-wing reflow; not optimized for flex or direct-mount use cases. | Choose when leveraging existing SOIC-8 footprint or requiring test pin access (Pin 3) and decoupling pin (Pin 7) unavailable in DMP-4. |
Compared with MLX90373KVS-ABA-303-SP, the TSSOP-16 alternative adds hardware redundancy at cost of size and power, while the SOIC-8 version retains identical sensing capability but requires conventional PCB mounting - making the DMP-4 variant optimal for ultra-compact, PCB-less deployments in throttle bodies or pedal modules.

FAQ
What is the function of Pin 3 on the MLX90373KVS-ABA-303-SP?
Pin 3 on the MLX90373KVS-ABA-303-SP is designated N.C. (Not Connected) and has no internal circuit connection. Per the datasheet, it must remain unconnected in all designs to prevent unintended coupling or reliability risks. This differs from SOIC-8 and TSSOP-16 variants, which assign Pin 3 to VDD or TEST functions - confirming the DMP-4 package's simplified 4-terminal architecture.
Does the MLX90373KVS-ABA-303-SP support stray-field immunity?
No, the MLX90373KVS-ABA-303-SP does not support stray-field immunity. Its option code "-303" places it in Legacy/Linear-Angular mode, which requires ≥11 mT useful magnetic field norm but lacks the stray-field rejection capability specified for -10x variants. Stray-field immunity up to 5 mT is exclusive to -10x option codes and is not enabled or characterized for MLX90373KVS-ABA-303-SP.
What PSI5 cycle time ranges does the MLX90373KVS-ABA-303-SP support?
The MLX90373KVS-ABA-303-SP supports PSI5 cycle times from 300 µs to 500 µs, compliant with both v1.3 and v2.1 specifications. This range enables flexible ECU synchronization and accommodates varying bus loading conditions. The device's default latency is 850 µs and worst-case step response is 2125 µs - values measured under these defined cycle time boundaries and confirmed for the -30x configuration.
Can the MLX90373KVS-ABA-303-SP be programmed in-system?
Yes, the MLX90373KVS-ABA-303-SP supports end-user programming via PTC (Programming Through Connector) using the PSI5 interface. Users can configure transfer characteristics (4/8/17/32-point), filter settings, diagnostics thresholds, and velocity algorithms without requiring dedicated programming hardware - all stored in on-chip NVRAM with ECC protection for long-term integrity.
What is the maximum supply voltage for continuous operation of the MLX90373KVS-ABA-303-SP?
The MLX90373KVS-ABA-303-SP supports continuous operation up to 18 V supply voltage when used in DMP-4 or SOIC-8 packages, as specified in the Absolute Maximum Ratings table. This rating applies under normal operating conditions (TJ < 175°C) and ensures compatibility with 12 V automotive systems experiencing load dump transients. Exceeding 18 V for >24 hours may cause permanent damage.
