Product details
Overview
MLX90830LXG-BAH-001-SP from Melexis is an AEC-Q100-qualified absolute pressure sensor with ratiometric analog output, 0–10.342 bar full-scale range, ±0.5% FS lifetime accuracy, and automotive-grade operation from −40°C to +150°C. It integrates MEMS sensing, 16-bit microcontroller, analog front-end, voltage regulators, and diagnostics for thermal management in e-compressors and expansion valves.
For engineers reviewing the MLX90830LXG-BAH-001-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, calibrated transfer curve values, Triphibian® robustness data, ASIL-A safety compliance, and diagnostic configuration details essential for EV coolant and HVAC-R system integration.
Technical Context
The MLX90830LXG-BAH-001-SP implements Triphibian® suspended-cantilever MEMS technology for pressure spike immunity 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.
It features configurable diagnostics including broken connection detection, over/under-voltage monitoring (default thresholds: 4.2 V UV / 5.55 V OV), and fault-band signaling (0–3% VDD low band / 97–100% VDD high band). The device operates with 4.5–5.5 V supply, draws 9.5–12 mA typical current, and achieves 0.4 ms fastest response time.

FAQ
What is the calibrated pressure range of the MLX90830LXG-BAH-001-SP?
The MLX90830LXG-BAH-001-SP is factory calibrated for 0 to 10.342 bar (0–150 PSI) absolute pressure, with corresponding 0.5–4.5 V ratiometric analog output. This range is stored in on-chip EEPROM and validated across −40°C to +150°C per AEC-Q100 requirements. The MLX90830LXG-BAH-001-SP does not support field re-ranging without PTC04 programming tool and calibration fixture.
Does the MLX90830LXG-BAH-001-SP require external components for basic operation?
Yes - the MLX90830LXG-BAH-001-SP requires an external capacitor on the VAUX pin (Pin 13) for internal regulator stability, as specified in Figure 8 of the datasheet. A 100 nF X7R ceramic capacitor is recommended. No external ADC or signal conditioning is needed due to its integrated 16-bit microcontroller and ratiometric analog output.
How does the MLX90830LXG-BAH-001-SP indicate fault conditions?
The MLX90830LXG-BAH-001-SP signals faults by driving its analog output into defined fault bands: 0–3% VDD (Lower Fault Band) or 97–100% VDD (Upper Fault Band). These bands are triggered by broken connections (e.g., open GND or VSup) or enabled internal diagnostics such as over/under-voltage, membrane failure, or output errors - all configurable via EEPROM.
Is the MLX90830LXG-BAH-001-SP compatible with liquid refrigerants like R134a and R1234yf?
Yes - the MLX90830LXG-BAH-001-SP is chemically compliant with common refrigerants including R134a, R1234yf, R744 (CO₂), and R290 (propane), as confirmed in the datasheet's "Robust in gas and liquid media" feature and AEC-Q103-002 qualification. Its Triphibian® cavity-up construction prevents leakage paths and withstands freeze-thaw cycling in mixed-phase media.
Can the MLX90830LXG-BAH-001-SP be programmed after soldering to the PCB?
Yes - the MLX90830LXG-BAH-001-SP supports post-soldering programming via its TEST pins (9, 10, 12) using the Melexis PTC04 tool. This enables final-system calibration, diagnostic configuration, and EEPROM parameter updates without requiring socketed test fixtures - critical for production-line trim and variant management.
