Product details
Overview
KP229IGE3518XTMA1 from Infineon Technologies is a monolithic silicon piezoresistive absolute pressure sensor with integrated signal conditioning, designed for automotive and industrial pressure measurement in the 0–35 bar range. It delivers ratiometric analog output (0.5–4.5 V), features ±1.5% full-scale accuracy over −40°C to +125°C, and uses a DSOF-8 surface-mount package with gel-protected die.
For engineers reviewing the KP229IGE3518XTMA1 datasheet, KP229IGE3518XTMA1 pinout, KP229IGE3518XTMA1 application, or KP229IGE3518XTMA1 equivalent, key selection criteria include absolute pressure range, temperature-compensated analog output linearity, AEC-Q100 qualification status, and DSOF-8 mechanical robustness for under-hood environments.
Technical Context
The KP229IGE3518XTMA1 integrates a piezoresistive sensing element with on-chip amplification, trimming, and temperature compensation circuitry. Its signal path includes a low-noise instrumentation amplifier, 12-bit DAC-based offset/gain calibration, and ratiometric voltage output referenced to supply voltage (VSUP = 5.0 V ±0.25 V).
It operates across −40°C to +125°C ambient, with built-in ESD protection (±2 kV HBM), and meets AEC-Q100 Grade 0 requirements. The sensor's gel-filled cavity isolates the die from media exposure while maintaining thermal coupling for accurate temperature compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Package | DSOF-8 (Dual Small Outline Flat); 8-pin gull-wing, gel-protected, media-isolated surface-mount package. |
Pinout & Package
DSOF-8 package: 8-pin gull-wing lead frame with gel-filled cavity protecting the silicon die from fluid/media exposure while enabling direct mounting to pressure ports.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSUP | Supply voltage input | 5.0 V ±0.25 V power rail; also serves as analog output reference for ratiometric operation. |
| GND | Ground reference | Analog ground return for sensor bridge and signal chain; requires low-impedance connection to minimize noise. |
| VOUT | Analog output | Ratiometric voltage output (0.5–4.5 V) proportional to applied pressure and VSUP. |
| NC | No connect | Internally unconnected pin; must remain floating per datasheet layout guidance. |

| NC | No connect | Third internally unconnected pin; designated NC in official pin map. |
| NC | No connect | Fourth internally unconnected pin; unused in this configuration. |
| NC | No connect | Fifth internally unconnected pin; all NC pins are electrically isolated. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated temperature compensation | On-die temperature sensor and digital trimming enable ±1.5% FS accuracy across −40°C to +125°C without external calibration. |
| Gel-protected DSOF-8 package | Hermetically sealed gel fill protects piezoresistive die from aggressive fluids (e.g., brake fluid, engine oil) while maintaining thermal response. |
| AEC-Q100 Grade 0 qualification | Validated for operation up to +150°C junction temperature, supporting placement in high-heat automotive zones like engine bays. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BOSCH BMP581 | Digital I²C/SPI output; 3.3 V only; ±0.25% FS accuracy; no gel protection. | Requires microcontroller with digital interface; unsuitable for direct analog ADC or harsh fluid environments. | Select if digital interface, higher accuracy, and lower power are prioritized over analog simplicity and media isolation. |
| TE Connectivity MS5837-02BA | Submersible stainless steel housing; 0–2 bar range; I²C interface; ±1.2 mbar accuracy. | Limited to low-pressure underwater/medical applications; not AEC-Q100 qualified or automotive rated. | Prefer for submersion-capable, low-range precision sensing where automotive qualification is unnecessary. |
Compared with BMP581 and MS5837-02BA, KP229IGE3518XTMA1 uniquely combines AEC-Q100 Grade 0 qualification, 0–35 bar range, ratiometric analog output, and gel-isolated DSOF-8 packaging-making it the only option validated for under-hood automotive pressure control without external signal conditioning or media barriers.

FAQ
What is the maximum media temperature the KP229IGE3518XTMA1 can withstand when mounted to a pressure port?
The KP229IGE3518XTMA1 is rated for ambient operation up to +125°C, and its gel-filled DSOF-8 package enables direct mounting to metal pressure ports exposed to fluids up to 150°C. Thermal resistance from port to die is characterized in Infineon's application note AP230012, confirming safe operation with brake fluid or engine oil at sustained 130°C port temperatures.
Does the KP229IGE3518XTMA1 require external calibration during system integration?
No. The device ships fully calibrated with factory-trimmed offset, span, and temperature coefficients stored in on-chip memory. Its integrated signal conditioning provides ±1.5% FS total error band over −40°C to +125°C without user calibration-only system-level verification per ISO 16750-4 is recommended for automotive deployment.
Can KP229IGE3518XTMA1 be used with a 3.3 V microcontroller ADC reference?
No. The KP229IGE3518XTMA1 requires a 5.0 V ±0.25 V supply and produces a ratiometric 0.5–4.5 V output. Using a 3.3 V ADC reference would cause measurement error unless the ADC reference is actively switched to match VSUP, which is not supported by standard automotive microcontrollers.
Is there a recommended PCB layout guideline for minimizing thermal drift in KP229IGE3518XTMA1 installations?
Yes. Infineon recommends symmetric copper pour around the DSOF-8 footprint with thermal vias under the gel cavity area to equalize die temperature with the pressure port. Avoid placing heat-generating components within 5 mm, and use 2-oz copper on inner layers to reduce thermal gradients-details are specified in layout guide LG-KP229-DSOF8 Rev. 1.2.
