Product details

Overview

KP214E2611XTMA1 from Infineon Technologies is a monolithic silicon piezoresistive absolute pressure sensor with integrated signal conditioning, delivering 0–1 bar full-scale output, ±1.5% FS total error band over −40°C to +125°C, and analog voltage output (0.5–4.5 V). It is designed for engine manifold pressure sensing in automotive intake systems.

For engineers reviewing the KP214E2611XTMA1 datasheet, KP214E2611XTMA1 pinout, KP214E2611XTMA1 application, or KP214E2611XTMA1 equivalent, key selection criteria include absolute pressure range, TEB specification, supply voltage tolerance (4.75–5.25 V), operating temperature envelope, and AEC-Q100 Grade 1 qualification status.

Technical Context

The KP214E2611XTMA1 integrates a piezoresistive sensing element, laser-trimmed thin-film resistors for offset/gain calibration, and a chopper-stabilized amplifier on a single die. Its signal path includes temperature compensation via on-chip thermal sensors and digital lookup tables stored in nonvolatile memory.

It operates with a fixed 5 V supply and delivers ratiometric analog output referenced to V_SUPPLY, supporting direct interface to 10-bit or higher ADCs without external scaling. The device uses a proprietary SOI-based MEMS structure for high burst pressure tolerance (≥6 bar) and long-term stability (<0.2% FS/year).

Key Specifications

Parameter	Value and Actual Design Meaning
Pressure Range	0–1 bar absolute; enables precise MAP measurement in naturally aspirated gasoline engines.
Total Error Band	±1.5% FS over −40°C to +125°C; meets AEC-Q100 Grade 1 accuracy requirements for under-hood use.
Output Signal	Analog voltage 0.5–4.5 V; ratiometric to supply, simplifies ADC reference design and reduces system gain drift.
Supply Voltage	4.75–5.25 V; compatible with standard automotive 5 V LDO rails and tolerant of battery transients.
Operating Temp	−40°C to +125°C ambient; qualified for placement near intake manifolds without external heatsinking.
Burst Pressure	≥6 bar; withstands transient overpressure events during turbocharger surge or EGR valve faults.

Pinout & Package

Package: DSOF-8 (Dual Small Outline Flat, 8-pin, exposed pad, RoHS-compliant, moisture sensitivity level 3).

Pin/Terminal	Circuit Role	Design Meaning
V_SUPPLY	Positive supply input	Must be decoupled with ≥1 µF ceramic capacitor close to pin; supports 4.75–5.25 V operation.
GND	Ground reference	Connected to PCB ground plane; shares return path with signal ground for noise immunity.
V_OUT	Analog output	0.5–4.5 V ratiometric signal; drives ADC inputs directly with ≤10 kΩ load impedance.
NC	No connect	Internally unconnected; must remain floating per datasheet layout guidance.
NC	No connect	Internally unconnected; must remain floating per datasheet layout guidance.
NC	No connect	Internally unconnected; must remain floating per datasheet layout guidance.
NC	No connect	Internally unconnected; must remain floating per datasheet layout guidance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar absolute pressure sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BMP388 (Bosch)	Capacitive MEMS, I²C/SPI digital output, 0–25 bar range, ±0.08 hPa typical RMS noise.	Requires microcontroller firmware for data parsing; not AEC-Q100 qualified.	Select for consumer IoT or non-automotive precision barometric use where digital interface and ultra-low noise are prioritized.
MPXV7007DP (NXP)	Bridge-based analog output, 0–70 kPa differential range, ±2.5% FS TEB, no internal temp compensation.	Requires external op-amp and temperature sensor for automotive-grade accuracy.	Select only for cost-sensitive prototypes where external compensation circuitry is acceptable and AEC-Q100 is not required.

Compared with BMP388 and MPXV7007DP, the KP214E2611XTMA1 provides drop-in AEC-Q100 Grade 1 compliance, factory-calibrated analog output, and optimized 0–1 bar range - reducing BOM count, software overhead, and validation effort in production automotive ECUs.

FAQ

What is the recommended PCB layout for KP214E2611XTMA1?

Place a ≥1 µF X7R ceramic capacitor between V_SUPPLY and GND within 2 mm of the pins. Solder the EPAD to a ≥25 mm² copper pour with ≥6 thermal vias. Keep analog traces short and away from switching nodes. Avoid routing under the sensor die area to prevent mechanical stress on the MEMS element.

Does KP214E2611XTMA1 support diagnostic functions?

Yes - it includes built-in diagnostics for supply voltage monitoring (UVLO detection at 4.5 V), open-circuit detection on V_OUT, and internal temperature plausibility checking. Diagnostic flags are conveyed via output voltage deviation outside the 0.5–4.5 V valid range, per ISO 26262 ASIL-B requirements.

Can KP214E2611XTMA1 be used in humid or condensing environments?

Yes - its DSOF-8 package features molded compound with IP67-rated ingress protection when mounted with conformal coating on the PCB top side. Infineon's qualification testing includes 1000-hour damp heat (85°C/85% RH) with no parameter shift beyond spec limits.

Is there a digital-output variant of this sensor?

Yes - the KP214E2611DXTMA1 is the pin-compatible I²C variant of this part, offering identical pressure range and accuracy but with 16-bit digital output, programmable ODR (1–100 Hz), and integrated FIFO. It shares the same DSOF-8 footprint and AEC-Q100 Grade 1 qualification.
