Product details
Overview
MLX90372GVS-ACE-208-RX from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers SENT 3µs output with built-in capacitors in DMP-4 package, operates from -40°C to +160°C, supports ISO26262 ASIL-C safety element out of context, and enables non-contacting potentiometer replacement in automotive throttle and pedal systems.
For engineers reviewing the MLX90372GVS-ACE-208-RX datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4 Pinout-B), SENT timing compliance (SAE J2716 APR2016), stray-field immune operation, programmable transfer characteristic (32-point PWL), and functional safety architecture details critical for automotive sensor design and qualification.
Technical Context
The MLX90372GVS-ACE-208-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz components, an analog-to-digital signal conditioner, and a DSP for real-time angle decoding. Its DMP-4 package (Pinout-B) features dedicated Input pin for NTC or analog/digital gateway functions and built-in decoupling capacitors per section 15.3.
This variant uses ACE chip revision, STD4 2.54 trim & form (Option Code -208), and operates in Standard/Legacy mode (-300 code family) supporting both angular rotary and linear position measurement. It implements SENT 3µs timing with configurable frame structure and supports PWM output via programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-ACE-300-RX | Same DMP-4 Pinout-B package and ACE revision, but configured for Standard/Legacy mode with default 16-point PWL calibration. | Lacks the -208-specific STD4 2.54 trim & form and optimized capacitor configuration for high-volume automated assembly. | Select when legacy calibration profiles and standard packaging are sufficient; not recommended for new designs requiring optimized manufacturability. |
| MLX90371GVS-ACE-208-RX | Single-die predecessor with identical DMP-4 Pinout-B and -208 option code, but no ISO26262 ASIL-C certification or SENT secure format support. | Supports only basic SENT or PWM output without embedded diagnostics or CRC - limited to ASIL-A systems. | Choose only for cost-sensitive, non-safety-critical applications where functional safety compliance is not required. |
Compared with MLX90372GVS-ACE-208-RX, the -300 variant offers identical core functionality but less optimized mechanical form factor for SMT placement, while the MLX90371 alternative omits ASIL-C safety mechanisms and advanced SENT diagnostics - making the MLX90372GVS-ACE-208-RX the only choice for production automotive systems requiring certified functional safety and enhanced serial communication integrity.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACE-208-RX?
The MLX90372GVS-ACE-208-RX uses the DMP-4 (Dual Mould Package) with Pinout-B configuration: Pin 1 = OUT, Pin 2 = VSS, Pin 3 = VDD, Pin 4 = Input. It implements STD4 2.54 trim & form and ships face-down in tape-and-reel (RX packing), with built-in decoupling capacitors eliminating external components per datasheet section 15.3.
Does MLX90372GVS-ACE-208-RX support SENT and PWM outputs simultaneously?
No - the MLX90372GVS-ACE-208-RX supports either SENT or PWM output mode, selected during programming. It defaults to SENT 3 µs mode per its ACE-208 option code, and PWM must be explicitly enabled via end-user programmable items in the NVRAM. Both modes share the same OUT pin and cannot operate concurrently.
What is the meaning of "-208" in MLX90372GVS-ACE-208-RX?
The "-208" suffix denotes three configuration layers: "2" selects Standard/Legacy magnetic mode (rotary/linear), "0" selects SENT 3 µs timing with standard capacitor configuration, and "8" specifies STD4 2.54 trim & form for the DMP-4 package - all defined in Table 2 and section 18.13 of the datasheet revision 8.
Is MLX90372GVS-ACE-208-RX qualified for automotive use?
Yes - MLX90372GVS-ACE-208-RX is AEC-Q100 qualified, operates from -40°C to +160°C, and implements ISO26262 ASIL-C Safety Element out of Context (SEooC). It meets automotive EMC, thermal, and lifetime requirements for under-hood and cabin applications including throttle, pedal, and steering position sensing.
Can MLX90372GVS-ACE-208-RX be used for linear position sensing?
Yes - MLX90372GVS-ACE-208-RX supports both absolute rotary and linear position measurement in Standard/Legacy mode (-300 family). When paired with a linear magnet trajectory and calibrated using its 32-point PWL function, it achieves ±0.5 mm linearity over typical stroke lengths, as validated in application examples and section 8.4 of the datasheet.
