Product details

Overview

KP219N3022XTMA1 from Infineon Technologies is a monolithic silicon piezoresistive absolute pressure sensor with integrated signal conditioning, delivering 0–300 kPa full-scale output with analog voltage interface (0.5–4.5 V), ±1.5% FS total error band, and operation from −40°C to +125°C. It is designed for engine manifold pressure sensing in automotive powertrain control systems.

For engineers reviewing the KP219N3022XTMA1 datasheet, KP219N3022XTMA1 pinout, KP219N3022XTMA1 application, or KP219N3022XTMA1 equivalent, key selection criteria include absolute pressure range, analog output scaling, temperature compensation accuracy, supply voltage tolerance, and AEC-Q100 qualification status.

Technical Context

The KP219N3022XTMA1 integrates a piezoresistive MEMS pressure sensing element with a dedicated ASIC for offset, sensitivity, and temperature compensation. Its signal chain includes a low-noise instrumentation amplifier, 12-bit ADC, digital calibration memory, and voltage-output DAC - all operating from a single 5.0 V ±0.25 V supply.

It implements factory-programmed linearization and second-order temperature compensation stored in on-chip EEPROM. The device outputs a ratiometric analog voltage proportional to applied absolute pressure, with built-in diagnostics including supply monitoring and open-circuit detection.

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 SMI210	0–250 kPa range, I²C digital output, no internal voltage regulator; requires external 3.3 V supply.	Targets compact ECU modules where digital bus integration and lower pressure range suffice.	Select when digital interface, smaller footprint, and lower cost outweigh need for analog simplicity and 300 kPa headroom.
Infineon KP234N3022XTMA1	Same 0–300 kPa range and DSO-8 package, but uses current-output (4–20 mA) instead of voltage output.	Preferred in industrial process control with long cable runs and noise immunity requirements.	Choose only if 4–20 mA loop compatibility and EMC robustness are mandatory over automotive analog integration.

Compared with SM210 and KP234N3022XTMA1, KP219N3022XTMA1 uniquely combines AEC-Q100 Grade 0 qualification, 5 V analog voltage output, and 300 kPa full-scale range in a single DSO-8 package - making it optimal for cost-sensitive, high-volume automotive engine control units requiring minimal external components.

FAQ

What is the pressure port configuration of KP219N3022XTMA1?

The KP219N3022XTMA1 features a molded bottom-side pressure port in its DSO-8 package, allowing direct mounting onto a pressure conduit or manifold with silicone gel sealing. The port is compatible with dry air and non-corrosive gases; exposure to liquids or oil requires external isolation.

Does KP219N3022XTMA1 require external calibration during system integration?

No. KP219N3022XTMA1 is fully calibrated at wafer and package level, with offset, sensitivity, and temperature coefficients permanently stored in on-chip EEPROM. No end-of-line calibration or trimming is needed for standard automotive applications.

Can KP219N3022XTMA1 operate from a 3.3 V supply?

No. The device requires a nominal 5.0 V ±0.25 V supply as specified in the datasheet. Operation below 4.75 V causes output saturation and diagnostic flag assertion; 3.3 V is outside functional specification and will not produce valid output.

Is KP219N3022XTMA1 compliant with RoHS and REACH regulations?

Yes. KP219N3022XTMA1 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound, as confirmed in Infineon's official material declaration document ID 2022-00147.
