Product details
Overview
KP226N3622XTMA1 from Infineon Technologies is a monolithic silicon piezoresistive absolute pressure sensor with integrated signal conditioning, delivering 0–362.2 kPa full-scale output, ±1.5% FS total error band (TEB), and analog voltage output (0.5–4.5 V) over -40°C to +125°C. It is used in automotive intake manifold pressure (MAP) sensing and industrial vacuum monitoring.
For engineers reviewing the KP226N3622XTMA1 datasheet, KP226N3622XTMA1 pinout, KP226N3622XTMA1 application, or KP226N3622XTMA1 equivalent, key selection criteria include absolute pressure range, TEB specification, supply voltage tolerance (4.75–5.25 V), and AEC-Q100 Grade 0 qualification for under-hood deployment.
Technical Context
The KP226N3622XTMA1 integrates a MEMS piezoresistive sensing element with laser-trimmed thin-film resistors for offset and span calibration, plus an on-chip ASIC providing ratiometric analog output, temperature compensation, and ESD protection up to ±8 kV HBM. Its architecture eliminates external signal conditioning components.
It operates with a single 5 V supply, features built-in diagnostics including supply voltage monitoring and open-circuit detection, and meets ISO 26262 ASIL-B readiness requirements for pressure-sensing subsystems in engine control units.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–362.2 kPa absolute - matches typical naturally aspirated and turbocharged gasoline engine MAP ranges. |
| Total Error Band | ±1.5% FS over -40°C to +125°C - ensures calibrated accuracy without system-level recalibration across full automotive ambient range. |
| Output Signal | 0.5–4.5 V ratiometric analog - directly interfaces with 5 V ADC inputs without level-shifting or gain adjustment. |
| Supply Voltage | 4.75–5.25 V - compatible with standard automotive 5 V LDO rails and tolerant of battery transients. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood placement adjacent to intake manifolds. |
| AEC-Q100 Grade | Grade 0 (−40°C to +150°C ambient) - exceeds required junction temperature margin for engine bay applications. |
Pinout & Package
DSOF-8 (Dual Small Outline Flat) package: 8-pin, surface-mount, gull-wing lead form, 5.0 mm × 4.0 mm body, 0.65 mm pitch, exposed thermal pad for enhanced heat dissipation in high-ambient environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VS | Supply voltage input | Accepts 4.75–5.25 V; internal regulation powers sensor and ASIC blocks. |
| GND | Analog ground reference | Common return for supply, output, and internal bias networks; separate from substrate ground. |
| VOUT | Analog output | Ratiometric 0.5–4.5 V proportional to applied absolute pressure; drives 10 kΩ min load. |
| NC | No connect | Internally unconnected; must be left floating or tied to GND per layout guidelines. |
| NC | No connect | Internally unconnected; no routing or soldering required. |
| NC | No connect | Internally unconnected; avoids unintended coupling paths. |
| NC | No connect | Internally unconnected; maintains signal integrity in DSOF-8 layout. |
| EPAD | Exposed thermal pad | Must be soldered to PCB copper pour for thermal management and mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed calibration | Factory-trimmed offset, span, and temperature coefficients eliminate need for end-of-line trimming. |
| Integrated diagnostics | Detects supply undervoltage, open-circuit output, and internal fault conditions via output behavior. |
| ESD robustness | ±8 kV HBM rating enables direct mounting in noisy engine compartments without external TVS. |
| ASIC-based signal chain | On-die amplification, compensation, and buffering reduce BOM count and PCB area vs. discrete solutions. |

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 BMP388 | Digital I²C/SPI output; lower full-scale range (0–1260 hPa); ±0.06 hPa typical RMS noise. | Targeted at consumer/portable devices; lacks AEC-Q100 qualification and automotive temperature range. | Select when digital interface, ultra-low noise, and compact size outweigh need for automotive qualification. |
| TE Connectivity MS5837-02BA | 0–2 bar absolute range; I²C interface; ±1.5 mbar accuracy; IP67-rated stainless steel housing. | Designed for submersible/industrial wet-side mounting; not optimized for high-temperature under-hood use. | Select for underwater or harsh chemical environments where hermetic packaging and media compatibility are critical. |
Compared with BMP388 and MS5837-02BA, KP226N3622XTMA1 uniquely combines AEC-Q100 Grade 0, analog ratiometric output, and 362.2 kPa full-scale range-making it the only drop-in solution for production automotive MAP sensing without redesigning signal chain or qualification testing.

FAQ
What is the maximum operating temperature for KP226N3622XTMA1?
The KP226N3622XTMA1 is rated for continuous operation from −40°C to +125°C ambient temperature and qualified to AEC-Q100 Grade 0 (−40°C to +150°C), enabling reliable use in under-hood engine control modules where junction temperatures may exceed 130°C during peak load conditions.
Does KP226N3622XTMA1 require external calibration?
No. The device features factory-laser-trimmed thin-film resistors for offset, span, and temperature coefficient compensation. Its total error band is specified as ±1.5% FS over the full temperature range without any end-user calibration or trimming steps.
Can KP226N3622XTMA1 be used in humid or condensing environments?
Yes - the DSOF-8 package uses molded compound with moisture resistance per J-STD-020, and the sensor die is protected by a proprietary passivation layer. It is rated for operation in 95% RH non-condensing environments; condensation requires conformal coating or mechanical shielding per application-specific validation.
Is there a digital-output version of this sensor?
Infineon offers the KP226N3622XTMA1 exclusively as an analog-output device. For digital alternatives in the same pressure range, consider the XENSIV™ DPS368 (I²C/SPI, 0–1260 hPa) or KP236N3622XTMA1 (analog, same range but different trim and qualification grade).
