Product details
Overview
MLX90830LXG-BAF-002-RE from Melexis is an AEC-Q100- and AEC-Q103-002-qualified absolute pressure sensor with ratiometric analog output, 0–34.474 bar full-scale range, ±0.5% FS lifetime accuracy, and automotive-grade operation from −40°C to +150°C. It integrates MEMS sensing element, 16-bit microcontroller, analog front-end, voltage regulators, and diagnostics in a single SOIC16 WB package - deployed in e-compressor and expansion valve pressure monitoring for EV thermal management.
For engineers reviewing the MLX90830LXG-BAF-002-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its 34.474 bar pressure span, 0.4 ms fast response time, ASIL A SEooC compliance per ISO 26262, Triphibian® robustness against frozen/liquid media, and factory-programmable diagnostics via PTC04 tool.
Technical Context
The MLX90830LXG-BAF-002-RE implements a MEMS diaphragm with piezoresistive Wheatstone bridge and Triphibian® suspended cantilever architecture, enabling 210 bar burst pressure and immunity to pressure spikes up to 2000 bar/msec. Its DSP-based signal chain performs real-time temperature compensation (up to third-order for offset/gain) and pressure linearization using on-chip EEPROM-stored calibration coefficients.
Diagnostics are fully configurable via EEPROM: broken connection detection forces output into fault bands (0–3% or 97–100% VDD), while internal sources - including over/under-voltage, internal regulator faults, and membrane integrity - can be assigned independently to low or high fault bands. The device supports 4.5–5.5 V supply, withstands ±40 V transients, and delivers 0.5–4.5 V ratiometric analog output with 2 mVrms noise in default configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 34.474 bar absolute - calibrated full-scale span for high-pressure refrigerant and coolant monitoring in EV e-compressors. |
| Output Signal | 0.5 to 4.5 V ratiometric analog - output scales linearly with supply voltage, enabling stable readings despite rail variation in noisy automotive environments. |
| Accuracy | ±0.5% full scale lifetime accuracy - guaranteed over life and temperature, with ±172 mbar pressure error at typical conditions. |
| Response Time | 0.4 ms (fastest mode) - enables real-time closed-loop control of fast-acting thermal valves and compressors. |
| Operating Temp | −40°C to +150°C - qualified for under-hood and powertrain locations without external thermal shielding. |
| Supply Voltage | 4.5–5.5 V nominal, ±40 V transient tolerant - eliminates need for external TVS or reverse-polarity protection in 12/24 V systems. |
| Diagnostic Coverage | Configurable broken-connection, over/under-voltage, and internal regulator fault detection - outputs fault bands (0–3% or 97–100% VDD) for fail-safe system response. |
Pinout & Package
MLX90830LXG-BAF-002-RE uses a SOIC16 WB (wide-body) cavity-up package with 16 leads. The package features an open cavity exposing the MEMS die to media, sealed via gasket or direct media contact per application requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 15, 16 | NC | No internal connection - left unconnected on PCB; no routing or pull-up/pull-down required. |
| 3, 6, 11, 14 | GND | Ground reference for analog and digital circuits - multiple pins reduce impedance and improve EMC performance. |
| 7 | VSup | Main supply input (4.5–5.5 V) - includes ±40 V over/under-voltage protection circuitry. |
| 8 | Analog OUT | Ratiometric analog output (0.5–4.5 V) - clamped to 0.3–4.7 V; fault bands at 0–3% or 97–100% VDD. |
| 13 | VAUX | Auxiliary capacitor connection - stabilizes internal voltage regulators; requires 1 µF ceramic capacitor to GND. |
| 9, 10, 12 | TEST | Factory test pins - not intended for end-user access; left floating or tied to GND per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Triphibian® MEMS architecture | Suspended cantilever design provides inherent immunity to pressure spikes (2000 bar/msec) and frozen media, eliminating differential stress across pedestal/bonding surfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5700AP | 70 bar range, but only ±2% FS accuracy, no ASIL compliance, no programmable diagnostics, and −40°C to +125°C rating. | Limited to non-safety-critical HVAC or industrial monitoring where diagnostic coverage and extended temperature are not required. | Select MPX5700AP only for cost-sensitive, non-automotive designs lacking functional safety mandates. |
| INFINEON DPS368 | I²C digital output, ±0.05% FS relative accuracy (not absolute), 12 bar max range, −40°C to +85°C - lacks media robustness and automotive qualification. | Suitable for consumer electronics or indoor environmental sensing, not for refrigerant/coolant or under-hood deployment. | Choose DPS368 only for low-power, board-level barometric sensing - not for high-pressure, media-immersed, or ASIL-targeted use cases. |
Compared with MPX5700AP and DPS368, MLX90830LXG-BAF-002-RE uniquely combines 34.474 bar absolute range, ±0.5% FS lifetime accuracy, ASIL A SEooC compliance, Triphibian® media resilience, and configurable diagnostics - making it the only option qualified for safety-critical EV thermal management subsystems.

The MLX90830LXG-BAF-002-RE is factory configured for 0 to 34.474 bar (0 to 500 PSI) absolute pressure measurement. This range is laser-trimmed and stored in on-chip EEPROM during final test, ensuring traceable calibration across its full automotive temperature range (−40°C to +150°C).
Is MLX90830LXG-BAF-002-RE qualified for automotive applications?
Yes, MLX90830LXG-BAF-002-RE is qualified to AEC-Q100 Grade 0 and AEC-Q103-002 for pressure sensors. It is developed as an ASIL A Safety Element out of Context per ISO 26262, with documented FMEDA, diagnostic coverage metrics, and safety manual available from Melexis for integration into higher-ASIL systems.
How is the analog output of MLX90830LXG-BAF-002-RE ratiometric?
The MLX90830LXG-BAF-002-RE outputs a voltage from 0.5 V to 4.5 V that maintains a fixed ratio to the supply voltage (VDD). For example, at VDD = 5.0 V, full-scale output is 4.5 V; at VDD = 4.8 V, full-scale output scales to 4.32 V - preserving measurement integrity despite supply rail variation in automotive electrical systems.

No, MLX90830LXG-BAF-002-RE is programmed once during final test using the Melexis PTC04 programming tool. While EEPROM stores calibration and diagnostic settings, field reprogramming is not supported. Configuration changes require factory rework or selection of a different option code (e.g., BAH-004 for 20 bar range).
What package type does MLX90830LXG-BAF-002-RE use?
MLX90830LXG-BAF-002-RE uses a SOIC16 WB (wide-body) package with cavity facing up. This open-cavity construction allows direct media exposure to the MEMS die, and the package is qualified for gasket-sealed or overmolded mounting in refrigerant and coolant environments per AEC-Q103-002.
