Product details
Overview
KP200XTMA2 from Infineon is a PRO-SIL™ automotive pressure sensor designed for side-impact crash detection in passenger car door modules. It delivers a digital Manchester-encoded relative pressure signal (Δp/p₀) with ±200 kPa input range, operates from 4.5–11.0 V supply, and features on-chip voltage regulation, EEPROM for calibration/mode storage, and PSI5-compatible 2-wire synchronous/asynchronous communication.
For engineers reviewing the KP200XTMA2 datasheet, KP200XTMA2 pinout, KP200XTMA2 application, or KP200XTMA2 equivalent, this device requires attention to its AEC-Q100 qualification, PG-DSOF-8-16 package thermal resistance (180 K/W), ambient pressure compensation architecture, and PSI5 protocol timing constraints (e.g., 228 µs frame interval in asynchronous mode).
Technical Context
The KP200XTMA2 implements on-die division of absolute pressure change by ambient pressure (p₀) using a low-pass filtered p₀ estimate, enabling true relative pressure output independent of altitude or barometric drift. Its PSI5 interface supports three modes: synchronous P10P-500/3L (500 kbps), P10P-250/1L (250 kbps), and asynchronous A10P-250/1L (250 kbps, 228 µs frame period).
It integrates a current-modulated 2-wire Manchester transceiver, on-chip voltage regulator (VDD/CAP pins), and EEPROM for persistent ID, calibration data, and mode selection-enabling autonomous operation without external logic ICs in the pressure satellite node.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–11.0 V - powers internal regulator and sensor core; supports battery-supplied automotive environments with transient tolerance up to ±16.5 V. |
| Input Pressure Range | 10–600 kPa - covers crash-induced Δp pulses (up to 200 kPa typical) and withstands short-duration overpressure (≤300 s). |
| Ambient Pressure Range | 53.6–110.0 kPa - defines valid p₀ operating window for on-chip relative pressure calculation. |
| Operating Temperature | −40 °C to +85 °C - qualified per AEC-Q100 Grade 2 for under-door module placement. |
| PSI5 Frame Interval | 228 µs ± clock variation - fixed timing in asynchronous mode enables deterministic ECU sampling without external clock sync. |
| Lifetime | 15 years - specified under biased conditions with defined thermal profile (e.g., 7800 h at +52 °C). |
| Thermal Resistance | 180 K/W - die-to-pin thermal path impacts self-heating during sustained operation in sealed door cavities. |
Pinout & Package
Package: PG-DSOF-8-16 - 8-pin, exposed-pad, surface-mount package with silicone-gel passivated die and bond wires fully encapsulated for automotive reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply input | Accepts 4.5–11.0 V; powers internal regulator and sensor; overvoltage detection disables Manchester output above 16.5 V. |
| I_OUT | Current-modulated output line | 2-wire PSI5 Manchester signal carrier; bidirectional current modulation (±1.5 mA typical) encodes data without separate ground return. |
| CAP | Regulator bypass capacitor terminal | Connects external 0–4.7 µF capacitor; no DC voltage source allowed-only decoupling for internal LDO stability. |
| DAT_IN | Asynchronous programming/data input | Accepts 0–1.0 V low / 2.3–3.3 V high logic; used for EEPROM programming pulses (10–30 °C only). |
| DAT_OUT | Manchester data output (open-drain) | Drives low/high levels (0–1.0 V / 2.3–3.4 V); limited to 0.1 mA sink/source for compatibility with ECU input thresholds. |
| CLK | External clock input (sync mode) | Enables synchronous PSI5 operation; accepts 0–1.0 V / 2.3–3.3 V logic; not used in asynchronous A10P mode. |
| CS | Chip select for programming | Active-low enable for EEPROM write cycles; must be held low during programming pulse application. |
| GND | Analog/digital reference ground | Common return for VDD, I_OUT, CAP; critical for accurate Δp/p₀ ratio computation and noise immunity in door cavity. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip relative pressure calculation | Divides Δp by p₀ using low-pass-filtered ambient pressure-eliminates altitude dependency and enables consistent crash thresholding across global vehicle fleets. |
| PSI5-A10P-250/1L asynchronous mode | Fixed 228 µs frame interval allows deterministic ECU polling without master clock synchronization-reducing wiring complexity in distributed airbag systems. |
| Integrated EEPROM | Stores unique ID, factory calibration coefficients, and user-selected PSI5 mode-enabling field-programmable configuration without rework or external memory. |
| AK-LV29 compliance | Fully compatible with AK-LV29 physical layer requirements for automotive PSI5 networks-ensuring interoperability with TLE7729 and other Infineon satellite interface ICs. |
| Autarky time limit | Maximum 2 ms buffer capacitor discharge time ensures reliable startup and fault-free operation during battery transients common in vehicle cranking events. |
Applications
| Side Impact Detection | Door Module Satellite Node |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar pressure-based side crash detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7025DP | Analog ratiometric output (0.2–4.7 V), no integrated PSI5 encoder or EEPROM; requires external ADC and microcontroller. | Suitable for custom-designed satellite nodes with existing MCU resources; lacks autonomous operation capability. | Select when legacy analog signal chain exists and PSI5 infrastructure is unavailable. |
| KP210XTMA2 | Same PG-DSOF-8-16 package and PSI5 interface, but extends input range to 0–1000 kPa and adds enhanced ESD (8 kV HBM on I_OUT). | Preferred for heavy-duty vehicles or enhanced crash severity discrimination where higher overpressure margin is required. | Select when future-proofing against stricter regulatory pressure thresholds or dual-use (side + rear impact) deployment. |
Compared with MPXV7025DP and KP210XTMA2, the KP200XTMA2 offers optimal balance of autonomous PSI5 operation, AEC-Q100 lifetime assurance, and cost-effective integration for mainstream passenger car side-impact systems-without over-specifying pressure range or ESD rating.

FAQ
What PSI5 communication modes does the KP200XTMA2 support?
The KP200XTMA2 supports three PSI5 modes: synchronous P10P-500/3L (500 kbps), P10P-250/1L (250 kbps), and asynchronous A10P-250/1L (250 kbps with fixed 228 µs frame interval). Mode selection is stored in on-chip EEPROM and configurable via DAT_IN/CS programming pulses.
How does the KP200XTMA2 achieve relative pressure measurement?
It calculates Δp/p₀ on-die by dividing the absolute pressure change (Δp) by ambient pressure (p₀), where p₀ is derived from a low-pass filtered absolute pressure reading. This eliminates altitude-related offset and ensures consistent crash thresholding across diverse geographic operating conditions.
Is external circuitry required for KP200XTMA2 operation?
No external logic ICs are required: the device integrates a voltage regulator (CAP pin), EEPROM, Manchester encoder, and PSI5 transceiver. Only a 0–4.7 µF capacitor on CAP and standard 2-wire PSI5 bus termination (typically 100 Ω + 10 nF) are needed for basic operation.
What mechanical and environmental qualifications apply to KP200XTMA2?
The device is qualified per AEC-Q100 Grade 2 (−40 °C to +105 °C case temperature), withstands 2000 g mechanical shock (0.5 ms), and features gel-passivated die construction. Its PG-DSOF-8-16 package meets automotive vibration, humidity, and thermal cycling requirements for under-door module placement.
