Product details
Overview
MLX90830-LXG-BAG-003-SP from Melexis is an AEC-Q100- and AEC-Q103-002-qualified absolute pressure sensor with ratiometric analog output, Triphibian® MEMS technology, ±0.5% full-scale lifetime accuracy, and 0–4 bar (0–58 PSI) measurement range. It integrates MEMS die, 16-bit microcontroller, analog front-end, voltage regulators, and diagnostics in a single SOIC16 WB package for automotive coolant monitoring and HVAC-R liquid/gas sensing.
For engineers reviewing the MLX90830-LXG-BAG-003-SP datasheet, pinout, applications, or equivalent options, key selection considerations include its ASIL A SEooC compliance per ISO 26262, fast 0.4 ms response time, extended ±40 V supply/output protection, factory calibration with PTC04 programmability, and robust operation from –40°C to +150°C.
Technical Context
The MLX90830-LXG-BAG-003-SP implements a Triphibian® suspended-cantilever MEMS diaphragm with built-in vacuum reference cavity, enabling immunity to pressure spikes up to 2000 bar/msec and burst resistance to 210 bar. Its DSP-based signal chain performs real-time temperature compensation using third-order EEPROM-programmable offset (O0–O3) and gain (G0–G3) coefficients.
Diagnostics include configurable broken-connection detection (triggering fault bands at 0–3% or 97–100% of VDD), over/under-voltage monitoring (default thresholds: 4.2 V UV, 5.55 V OV), and internal error reporting via analog output clamping. The device operates with 4.5–5.5 V nominal supply, draws 9.5–12 mA, and delivers a 0.5–4.5 V ratiometric output linearly proportional to absolute pressure across its 0–4 bar span.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90821LXG-BAH-001-SP | SOIC8 package; 0–10.342 bar range; no TEST/VAUX pins; lower pin count | Limited to lower-pressure HVAC-R and industrial fluid control; lacks diagnostic configurability of MLX90830-LXG-BAG-003-SP | Select when space-constrained PCB layout and 10 bar range suffice, and ASIL A SEooC compliance is not required. |
| INFINEON DPS368XTSA1 | I²C digital output; 0–1200 hPa (0–1.2 bar) range; ±0.005 hPa RMS noise; no analog ratiometric output | Targeted at barometric and low-pressure environmental sensing; unsuitable for 4 bar liquid media or automotive coolant monitoring | Choose only for ultra-low-noise atmospheric pressure measurement where digital interface and sub-mbar resolution are critical. |
Compared with MLX90821LXG-BAH-001-SP and INFINEON DPS368XTSA1, the MLX90830-LXG-BAG-003-SP uniquely combines 4 bar analog ratiometric output, Triphibian® liquid/gas robustness, ASIL A SEooC compliance, and programmable diagnostics-making it the only option qualified for embedded e-compressor and automotive coolant applications requiring functional safety integration.

FAQ
What is the maximum qualified operating pressure for MLX90830-LXG-BAG-003-SP?
The MLX90830-LXG-BAG-003-SP is qualified for continuous operation up to 4 bar (58 PSI) absolute pressure, with a maximum qualified operating pressure of 8 bar as noted in the revision history. This rating applies to both gas and liquid media, including refrigerants and automotive coolants, under full AEC-Q103-002 qualification scope.
Does MLX90830-LXG-BAG-003-SP require external calibration after soldering?
No, MLX90830-LXG-BAG-003-SP is factory calibrated and fully programmed before shipment. Its third-order temperature compensation coefficients (O0–O3, G0–G3) and 0–4 bar transfer curve are stored in on-chip EEPROM. No post-soldering calibration is needed unless custom reprogramming via PTC04 tool is performed for application-specific tuning.
Can MLX90830-LXG-BAG-003-SP operate with a 3.3 V supply?
No, MLX90830-LXG-BAG-003-SP requires a nominal supply of 4.5–5.5 V and is not specified for 3.3 V operation. Its absolute maximum ratings define 40 V overvoltage tolerance but do not extend to under-voltage operation below 4.5 V. Supplying less than 4.5 V may cause undefined behavior, failure to power up, or invalid output clamping.
How does the broken-connection diagnostic work on MLX90830-LXG-BAG-003-SP?
The MLX90830-LXG-BAG-003-SP monitors supply and ground integrity continuously. If VSup or any GND pin is disconnected or shorted, the analog output shifts to a fault band: 0–3% of VDD (Lower Fault Band) or 97–100% of VDD (Upper Fault Band), depending on configuration. This enables immediate system-level fault detection without additional circuitry.
Is MLX90830-LXG-BAG-003-SP compatible with lead-free reflow soldering processes?
Yes, MLX90830-LXG-BAG-003-SP is qualified for lead-free reflow soldering per JEDEC J-STD-020. Melexis recommends a no-clean process and explicitly advises against flux cleaners due to its open-cavity SOIC16 WB package. Peak reflow temperature must not exceed the MSL rating indicated on the packing label, and PCB assembly must comply with IPC/JEDEC standards.
