Product details
Overview
KP212F1701 from Infineon Technologies is an analog absolute pressure sensor IC based on capacitive surface micromachining and monolithic BiCMOS signal conditioning. It delivers ratiometric voltage output (0.4 V to 4.65 V) across 10–115 kPa, with ±1.4 kPa accuracy at 0–85 °C, -40 °C to 125 °C operating temperature, and integrated broken-wire detection for automotive manifold air pressure measurement.
For engineers reviewing the KP212F1701 datasheet, KP212F1701 pinout, KP212F1701 application, or KP212F1701 equivalent, this page provides verified functional context, calibrated transfer behavior, PG-DSOF-8-16 package mapping, E²PROM-based linearization parameters, and OBD-compatible clamping thresholds - all critical for engine control unit (ECU) integration and ISO 26262-compliant diagnostics.
Technical Context
The KP212F1701 implements a third-order polynomial digital linearization algorithm using factory-stored E²PROM coefficients (90+22 bit), enabling precise conversion of capacitive pressure sensing into a ratiometric analog output. Its internal clock generator (30 kHz) drives ADC (10-bit) and DAC (12-bit) stages, while temperature compensation and offset/gain correction are applied in real time.
Clamping circuitry enforces defined overvoltage/undervoltage thresholds (VDD and GND referenced), enabling robust open-bond detection without external components. The dual-GND pin layout (Pins 6 & 8) and floating TEST/CLOCK/DATA pins support automotive-grade grounding integrity and ESD-safe calibration handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 10 kPa to 115 kPa absolute - calibrated linear span for intake manifold vacuum and boost monitoring in ICE engines. |
| Output Voltage | 0.4 V to 4.65 V ratiometric - scales directly with VDD (5 V typical), eliminating need for separate reference voltage in ECU analog front-end. |
| Accuracy | ±1.4 kPa (0–85 °C), ±2.1 kPa (-40 °C and 125 °C) - meets ASIL-B diagnostic requirements for closed-loop air-fuel ratio control. |
| Operating Temp | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1, enabling under-hood deployment without derating. |
| Ratiometric Error | ±0.5 % of VDD,Typ - ensures stable output scaling across supply variation in vehicle battery systems (4.5–5.5 V). |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard automotive 5 V LDO rails and immune to transient load dump effects. |
| Package | PG-DSOF-8-16 - "green" RoHS-compliant SMD housing with exposed thermal pad, optimized for reflow soldering and thermal stability. |
Pinout & Package
Package: PG-DSOF-8-16 - 8-pin surface-mount device with dual ground terminals (Pins 6 & 8), exposed thermal pad, and lead-free "green" finish compliant with JEDEC MS-012 standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (TEST) | Digital test interface | Used only during factory calibration; must remain floating in application to prevent cross-grounding via ESD diodes. |
| 2 (CLOCK / VPROG) | Serial programming clock / programming voltage input | Enables post-assembly EEPROM write; inactive during normal operation - tied to VDD or left open. |
| 3 (DATA IN) | Serial data input | Accepts calibration data during programming; high-impedance and unused in analog output mode. |
| 4 (DATA OUT) | Serial data output | Reads stored E²PROM coefficients; not used when operating in default analog output mode. |
| 5 (VDD) | Power supply input | Primary 4.5–5.5 V supply rail; powers analog signal chain, digital logic, and internal reference. |
| 6 & 8 (GND) | Circuit ground return | Both pins must be connected to minimize ground loop impedance and ensure accurate ratiometric output referencing. |
| 7 (VOUT) | Analog pressure output | Ratiometric voltage output (0.4–4.65 V); designed for direct connection to 12-bit ADC inputs in ECUs. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitive MEMS sensing element | Surface-micromachined silicon diaphragm with integrated BiCMOS signal conditioning - enables high long-term stability and low hysteresis (<0.15 kPa). |
| Factory-calibrated E²PROM | 90+22 bit storage for offset, gain, temperature coefficients, and third-order linearization coefficients - eliminates field calibration effort. |
| Broken wire detection (OBD) | Clamping-driven open-circuit diagnosis - detects VDD/GND interruption by forcing VOUT to rail voltages, enabling fail-safe ECU response. |
| Ratiometric output architecture | VOUT = VDD × (a × P + b), where a = 0.00810 1/kPa and b = −0.00095 - removes dependency on external voltage references in noisy automotive environments. |
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with lifetime reliability >15 years - suitable for powertrain and chassis control modules. |
Applications

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; 0.08 Pa RMS noise; no ratiometric analog output; requires external ADC and firmware integration. | Targets IoT and consumer wearables; lacks automotive qualification and OBD features. | Select if digital interface, ultra-low noise, and software-defined calibration are prioritized over plug-and-play analog integration. |
| TE Connectivity MS5837-02BA | 24-bit digital output; waterproof stainless steel housing; 0.2 mbar resolution; requires external voltage regulator and level-shifting. | Designed for underwater depth sensing; not AEC-Q100 qualified; no clamping or broken-wire detection. | Select for submersible or high-resolution barometric applications where automotive diagnostics are irrelevant. |
Compared with BMP388 and MS5837-02BA, the KP212F1701 uniquely combines AEC-Q100 qualification, ratiometric analog output, integrated OBD, and factory-trimmed E²PROM - making it the only drop-in solution for production automotive ECU designs requiring zero firmware modification and ISO 26262-aligned diagnostics.

FAQ
What is the maximum allowable supply voltage for KP212F1701?
The absolute maximum supply voltage is 6.0 V, but continuous operation must remain within 4.5 V to 5.5 V per datasheet Section 2.2. Exceeding 5.5 V risks permanent damage to the internal BiCMOS signal chain and E²PROM memory cells - no overvoltage protection is integrated beyond clamping on VOUT.
Does KP212F1701 require external calibration after soldering?
No. All calibration coefficients - including offset, gain, temperature coefficients, and third-order linearization parameters - are factory-programmed into on-chip E²PROM and applied automatically during operation. No external calibration or trimming is needed, even after reflow soldering or thermal cycling.
How does broken wire detection work without external circuitry?
Internal JFET-based clamping pulls VOUT to VDD if GND is disconnected, or to GND if VDD fails. The ECU monitors VOUT against programmable thresholds (e.g., <0.3 V or >4.8 V) to detect open-circuit faults - eliminating need for external comparators or watchdog circuits in ASIL-B designs.
Can KP212F1701 be used for differential pressure measurement?
No. The KP212F1701 is an absolute pressure sensor with a sealed reference cavity. It measures pressure relative to vacuum, not between two ports. For differential applications, Infineon's KP210 or KP220 series - which feature dual-port MEMS structures - must be selected instead.
