Product details
Overview
KP219M1203 from Infineon Technologies is an analog absolute pressure sensor IC designed for manifold air pressure (MAP) measurement in engine control units. It delivers ratiometric 0.5–4.5 V output over a 12.5–115 kPa pressure range, operates from −40 °C to +140 °C, achieves ±1.3 kPa total accuracy, and integrates broken-wire detection and clamping circuitry.
For engineers reviewing the KP219M1203 datasheet, KP219M1203 pinout, KP219M1203 application, or KP219M1203 equivalent, this page provides verified technical context, calibrated transfer function details, automotive-grade reliability data, and real-world use cases in engine management and industrial sensing systems.
Technical Context
The KP219M1203 employs a surface-micromachined capacitive sensing element monolithically integrated with BiCMOS signal conditioning circuitry. Its transfer function is linear and ratiometric to supply voltage, enabling stable operation across varying rail conditions in automotive environments.
It features internal diagnostics including broken-wire detection on the output line and active clamping to protect against overvoltage transients. The device meets AEC-Q100 Grade 0 requirements and supports fast power-up (< 10 ms) and pressure response times (< 10 ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 12.5 kPa to 115 kPa absolute - covers full MAP range for gasoline and diesel intake manifolds. |
| Output Voltage | 0.5 V to 4.5 V ratiometric - scales linearly with VDD, simplifying ADC reference coupling. |
| Total Accuracy | ±1.3 kPa at 25 °C - includes nonlinearity, hysteresis, repeatability, and temperature effects. |
| Operating Temp | −40 °C to +140 °C - qualified for under-hood automotive placement without external thermal shielding. |
| Supply Voltage | 4.75 V to 5.25 V - tight tolerance ensures stable biasing of internal reference and amplifier stages. |
| Power-Up Time | < 10 ms - enables rapid sampling after ignition-on, supporting transient engine condition capture. |
| Response Time | < 10 ms - allows tracking of dynamic pressure changes during throttle snap tests. |
Pinout & Package
Package: PG-DSOF-8-16 - green, lead-free, surface-mount SOIC-8 variant with exposed thermal pad for enhanced heat dissipation in high-temperature environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Supply input | 5 V nominal power rail; powers internal oscillator, reference, and signal chain. |
| GND | Ground reference | Analog and digital ground return; requires low-impedance connection to minimize noise coupling. |
| VOUT | Analog output | Ratiometric voltage proportional to applied pressure; includes built-in clamping and broken-wire detection. |
| NC | No connect | Internally unconnected pin; must remain floating per datasheet layout guidance. |
| NC | No connect | Second internally unconnected pin; no PCB trace or solder mask required. |
| NC | No connect | Third internally unconnected pin; unused in this configuration. |
| NC | No connect | Fourth internally unconnected pin; reserved for future variants. |
| NC | No connect | Fifth internally unconnected pin; not bonded or routed on die. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitive MEMS sensing element | Monolithic BiCMOS integration enables high SNR and long-term stability without external compensation. |
| Ratiometric output | Eliminates need for precision voltage references; output scaling tracks VDD variations within ±0.1%. |
| Broken-wire detection | Asserts open-circuit fault by pulling VOUT to 0.1 V when output line disconnects or shorts to ground. |
| Integrated clamping | Clamps VOUT to VDD + 0.3 V and GND − 0.3 V, protecting downstream ADC inputs from ESD or load dump. |
| AEC-Q100 Grade 0 qualification | Validated for operation up to +150 °C ambient, supporting placement near turbochargers or exhaust manifolds. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7025DP | Dual-port differential output; 0–25 kPa range; requires external op-amp for single-ended conversion. | Designed for differential pressure measurement only; not rated for 140 °C ambient. | Select when measuring pressure drop across filters or orifices, not absolute manifold pressure. |
| SSCDANT015PA3 | Digital I²C output; 0–15 psi (0–103 kPa); factory-calibrated with temperature compensation. | Lacks broken-wire detection and automotive qualification; max operating temp = +105 °C. | Select when digital interface, lower power, or simplified firmware integration outweighs diagnostic capability. |
Compared with MPXV7025DP and SSCDANT015PA3, the KP219M1203 uniquely combines automotive-grade temperature resilience, analog ratiometric output, and integrated diagnostics-making it optimal for safety-critical engine management where analog simplicity and fault coverage are mandatory.

FAQ
What is the recommended supply decoupling for KP219M1203?
Place a 100 nF X7R ceramic capacitor between VDD and GND, located ≤2 mm from the pins, plus a 1 µF tantalum or aluminum electrolytic capacitor on the board's main 5 V rail. This dual-stage filtering suppresses switching noise from ECUs and ensures stable internal reference operation across temperature.
Does KP219M1203 require external calibration during system assembly?
No. The KP219M1203 is fully factory-calibrated across pressure and temperature ranges. Its transfer function is trimmed during production to meet ±1.3 kPa accuracy without user calibration. Only system-level verification at end-of-line is required.
How does broken-wire detection behave during cold cranking?
During cold cranking, VDD may dip below 4.75 V. The KP219M1203 maintains broken-wire detection functionality down to 3.0 V supply, pulling VOUT to 0.1 V if the output line opens-enabling ECU fault logging even under low-voltage battery conditions.
Can KP219M1203 be used in humid or condensing environments?
Yes. The PG-DSOF-8-16 package uses moisture-resistant molding compound and qualifies to MSL3 per J-STD-020. When mounted with conformal coating and proper venting (per Infineon Application Note AN2012-09), it withstands sustained 95% RH exposure without drift or failure.
