Product details
Overview
MLX90822GXP-BAB-302-RE from Melexis is an AEC-Q100- and AEC-Q103-002-qualified absolute pressure sensor with ratiometric analog output, 0.1–4 bar full-scale range, ±0.5% FS lifetime accuracy, and operation from −40°C to +160°C (170°C short-term). It integrates MEMS die, CMOS interface IC, and three internal capacitors (C1=47nF, C2=C3=100nF) in a PCB-less SMP7 package for automotive manifold pressure sensing.
For engineers reviewing the MLX90822GXP-BAB-302-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, exact pin definitions, calibrated transfer curve parameters, diagnostic behavior, and OEM-grade EMC/ASIL-A compliance details required for engine control module integration.
Technical Context
The MLX90822GXP-BAB-302-RE implements a Wheatstone bridge MEMS diaphragm with piezo-resistive elements bonded to a vacuum cavity, coupled to a DSP-based CMOS interface IC that performs real-time temperature compensation (up to third-order offset/gain), pressure linearization, and clamping. Its analog output is ratiometric to VDD (4.5–5.5 V) and stable across −40°C to +160°C ambient.
Diagnostic functions include programmable over/under-voltage detection (default 5.7 V / 4.3 V), broken connection monitoring (output forced to <3% or >97% VDD), and internal fault reporting via fault bands. All diagnostics are configurable via EEPROM using the PTC04 programming tool, and the device is developed as an ASIL-A SEooC per ISO 26262.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0.1–4 bar absolute; validated burst pressure 16 bar - enables turbocharged ICE intake manifold monitoring without overpressure failure. |
| Output Signal | Ratiometric analog voltage: 0.5–4.5 V at VDD = 5 V - eliminates need for external reference and simplifies ADC scaling in ECU designs. |
| Accuracy | ±0.5% full scale lifetime accuracy - guaranteed over full temperature range and life cycle, critical for closed-loop air-fuel ratio control. |
| Response Time | Fastest 0.4 ms (90% settling); default 1 ms - supports high-speed transient pressure tracking in boosted engines. |
| Supply Voltage | 4.5–5.5 V nominal; survives −40 V reverse and +40 V overvoltage (≤2 hrs) - ensures robustness against load dump and battery reversal in vehicle systems. |
| Operating Temp | −40°C to +160°C continuous; +170°C for ≤10 min (20 hrs total lifetime) - meets under-hood thermal requirements for modern powertrains. |
| Diagnostics | Configurable internal diagnostics (OV/UV, membrane break, regulator fault) and broken-wire detection - provides fail-safe output clamping for ASIL-A compliance. |
Pinout & Package
SMP7 package: 7-pin, PCB-less molded housing with ridges for direct glue sealing to pressure ports; no external PCB required. Dimensions: 10.0 × 7.5 × 4.5 mm (L×W×H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Ground (GND) | Primary ground connection; either Pin 1 or Pin 3 may be used - allows flexible layout routing and redundancy. |
| 2 | Analog Output | Ratiometric voltage output (0.5–4.5 V); includes integrated 100 nF capacitor - eliminates external filtering components. |
| 3 | Ground (GND) | Secondary ground terminal; electrically identical to Pin 1 - unused pin may float without performance impact. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon DPS310 | Digital I²C output; 0–126 kPa range (≈0–1.26 bar); ±0.05% FS relative accuracy; no built-in diagnostics or ASIL certification. | Requires external ADC, voltage translation, and safety software layer - unsuitable for direct MAP replacement in ASIL-A/B ECUs. | Select only for low-pressure HVAC or drone altimetry where digital interface and ultra-high resolution outweigh functional safety needs. |
| NXP MPX5700 | Analog output; 0–700 kPa (≈0–7 bar); ±1.5% FS accuracy; −40°C to +125°C; no AEC-Q103 qualification or programmable diagnostics. | Lacks burst pressure rating (>16 bar), harsh media resistance, and ASIL-A development evidence - limited to non-critical aftertreatment or cabin pressure roles. | Consider only for cost-sensitive industrial air compressors where 160°C operation and automotive qualification are unnecessary. |
Compared with DPS310 and MPX5700, the MLX90822GXP-BAB-302-RE uniquely combines 4-bar full-scale range, ±0.5% FS lifetime accuracy over −40°C to +160°C, ASIL-A SEooC compliance, and PCB-less SMP7 packaging - making it the only drop-in solution for turbocharged automotive MAP sensing requiring zero layout changes and full OEM validation support.

FAQ
What is the calibrated pressure range and output voltage span of the MLX90822GXP-BAB-302-RE?
The MLX90822GXP-BAB-302-RE is factory calibrated for a 0.1–4 bar absolute pressure range with a ratiometric analog output spanning 0.5 V to 4.5 V at nominal 5 V supply. This transfer curve is stored in on-chip EEPROM and can be reprogrammed using the PTC04 tool to match specific engine mapping requirements.
Does the MLX90822GXP-BAB-302-RE require external capacitors for stable operation?
No. The MLX90822GXP-BAB-302-RE integrates three passive components internally: C1 = 47 nF, C2 = 100 nF, and C3 = 100 nF. Its analog output includes a built-in 100 nF capacitor, eliminating the need for external filtering or decoupling components in standard applications.
How does the MLX90822GXP-BAB-302-RE handle supply faults such as reverse voltage or overvoltage?
The MLX90822GXP-BAB-302-RE withstands −40 V reverse voltage and +40 V overvoltage on both VDD and output pins for up to 2 hours. During such faults, it limits supply current to 20 mA and maintains diagnostic functionality - enabling robust operation in automotive electrical environments without external protection devices.
Is the MLX90822GXP-BAB-302-RE qualified for automotive safety-critical systems?
Yes. The MLX90822GXP-BAB-302-RE is developed as an ASIL-A Safety Element out of Context (SEooC) per ISO 26262, and qualified to AEC-Q100 Grade 0 (−40°C to +160°C) and AEC-Q103-002 for pressure sensors. Its diagnostic features and fault-output behavior support integration into ASIL-B and ASIL-C systems.
Can both GND pins (Pin 1 and Pin 3) be connected simultaneously in the MLX90822GXP-BAB-302-RE?
Either Pin 1 or Pin 3 may be used as the ground connection; connecting both is not required and offers no performance benefit. The unused GND pin may be left floating without affecting accuracy, EMC, or reliability - providing layout flexibility in constrained ECU designs.
