Product details
Overview
MLX90823GXP-BAD-308-SP from Melexis is a PCB-less, factory-calibrated relative pressure sensor delivering ratiometric analog output (0.5 V to 4.5 V) over a 0–1.0 bar pressure range, with ±0.5% full-scale lifetime accuracy and operation from −40°C to +160°C. It integrates MEMS sensing element, DSP-based interface IC, and three internal capacitors (C1 = 47 nF, C2 = C3 = 100 nF) in an SMP7 package for automotive crankcase ventilation and filter monitoring.
For engineers reviewing the MLX90823GXP-BAD-308-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, exact pin definitions, calibrated transfer curve values, ASIL-A-compliant diagnostics, and OEM-validated EMC performance - all specific to the BAD-308 variant.
Technical Context
The MLX90823GXP-BAD-308-SP implements a piezoresistive Wheatstone bridge on a silicon diaphragm, with analog front-end filtering and 16-bit microcontroller-based DSP compensation for temperature and nonlinearity. Its default transfer curve maps 0 bar → 0.5 V and 1.0 bar → 4.5 V, with clamping levels at 0.3 V (LCL) and 4.7 V (HCL).
It features programmable diagnostics including broken connection detection, over/under-voltage monitoring (default thresholds: 5.7 V OV / 4.3 V UV), and internal fault reporting via Upper/Lower Fault Band outputs (0–3% VDD or 97–100% VDD). All diagnostics are stored and configurable in on-chip EEPROM using the PTC04 tool.

Equivalent & Alternatives
The following parts are listed as comparable options for similar relative pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90823GXP-BAD-301-RE | Measures −0.2 to +0.5 bar; same accuracy, package, and diagnostics. | Designed for bidirectional pressure (e.g., turbocharger boost/vacuum); unsuitable for unidirectional 0–1.0 bar use cases. | Select only if bidirectional range and negative pressure capability are required - BAD-308 provides superior resolution for pure positive-pressure monitoring. |
| MPXV7025DP | Analog output (0.2–4.7 V), −25 to +25 kPa range, no integrated diagnostics or ASIL support. | Lacks broken-wire detection, overvoltage protection, and AEC-Q100 qualification - requires external fault management circuitry. | Choose only for cost-sensitive non-automotive applications where diagnostic coverage and harsh-environment validation are not required. |
Compared with MLX90823GXP-BAD-308-SP, BAD-301 offers bidirectional range but reduced resolution in the 0–1.0 bar region, while MPXV7025DP lacks integrated diagnostics, automotive qualification, and EMC-hardened packaging - making MLX90823GXP-BAD-308-SP the only option meeting full ASIL-A SEooC, 160°C operation, and glue-seal mechanical integration requirements.

FAQ
What is the calibrated pressure range of the MLX90823GXP-BAD-308-SP?
The MLX90823GXP-BAD-308-SP is factory calibrated for a 0 to 1.0 bar relative pressure range, mapping linearly to a 0.5 V to 4.5 V ratiometric analog output. This span is optimized for unidirectional positive-pressure applications such as air filter monitoring and brake booster vacuum sensing, with ±5 mBar typical pressure accuracy across the full operating temperature range.
Does the MLX90823GXP-BAD-308-SP require external capacitors for stable operation?
No, the MLX90823GXP-BAD-308-SP integrates all required passive components internally: C1 = 47 nF, C2 = 100 nF, and C3 = 100 nF. The output capacitor (C3) is built into the SMP7 package, eliminating the need for external filtering and enabling direct connection to a 5 V ADC reference - a key enabler of its PCB-less mechanical design.
How does the MLX90823GXP-BAD-308-SP indicate fault conditions on its analog output?
The MLX90823GXP-BAD-308-SP signals faults by driving its analog output into defined Upper Fault Band (97–100% VDD) or Lower Fault Band (0–3% VDD), outside the normal 4–96% VDD operating range. These bands are triggered by configurable diagnostics including broken supply/ground connections, over/under-voltage, and internal errors - enabling unambiguous system-level fault detection without additional digital interfaces.
Is the MLX90823GXP-BAD-308-SP qualified for automotive use?
Yes, the MLX90823GXP-BAD-308-SP is qualified per AEC-Q100 Grade 0 (−40°C to +160°C) and AEC-Q103-002 for pressure sensors. It is developed as an ASIL-A Safety Element out of Context per ISO 26262, validated to leading OEM EMC standards, and rated for harsh media exposure - making it suitable for safety-critical under-hood automotive applications.
Can the MLX90823GXP-BAD-308-SP be reprogrammed after installation?
Yes, the MLX90823GXP-BAD-308-SP supports full field reprogramming via its dedicated programming interface using the Melexis PTC04 tool. This allows customization of calibration curves, diagnostic thresholds (e.g., OV/UV limits), temperature compensation coefficients (O0–O3, G0–G3), and linearization parameters - all stored in on-chip EEPROM without requiring hardware modification.
