Product details
Overview
KP275E2616XTMA1 from Infineon Technologies is a digital turbo manifold absolute pressure (TMAP) sensor with integrated SENT interface and external NTC temperature sensor interface, delivering ±0.77% FS accuracy over 10–400 kPa range, 12-bit pressure/temperature resolution, and automotive-grade operation from −40 °C to +150 °C (peak +170 °C), deployed in diesel and gasoline engine ECU pressure-temperature fusion systems.
For engineers reviewing the KP275E2616XTMA1 datasheet, KP275E2616XTMA1 pinout, KP275E2616XTMA1 application, or KP275E2616XTMA1 equivalent, key selection considerations include SENT protocol timing compliance, NTCIN signal conditioning capability, clamping level (0–4088 LSB), programmable transfer functions for pressure (10–400 kPa) and temperature (−50 to +170 °C), and green 8-pin SMD housing qualification per AEC-Q100.
Technical Context
The KP275E2616XTMA1 integrates a MEMS pressure cell, voltage regulator, NTC signal conditioner, 12-bit ADC, digital core (iSM), EEPROM for calibration data, and SENT physical layer driver - all on a single die. It supports dual-signal acquisition: pressure via internal piezoresistive element and temperature via external NTC connected to NTCIN.
Its SENT output delivers real-time pressure and temperature data in a single frame using configurable message structure (e.g., 12-bit pressure + 12-bit temperature + status bits), with built-in self-diagnostic features including open-circuit detection on NTCIN, supply monitoring, and EEPROM CRC validation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Accuracy | ±0.77% full-scale span (FSS) - enables CO₂ emission compliance in modern turbocharged engines |
| Pressure Range | 10–400 kPa - covers full manifold vacuum-to-boost range for gasoline/diesel turbo applications |
| Temperature Range | −40 °C to +150 °C continuous, +170 °C peak - qualified for under-hood ECU placement |
| Output Interface | SENT (Single Edge Nibble Transmission), 12-bit pressure + 12-bit temperature - eliminates analog wiring, reduces EMI susceptibility |
| NTC Interface | NTCIN pin with dedicated conditioning circuit - supports standard 10 kΩ NTCs with programmable bias and filtering |
| Supply Voltage | 4.5–5.5 V - compatible with standard 5 V automotive rail, includes internal regulator for analog/digital domains |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | 5 V nominal supply for digital core and interface driver; internal regulator feeds analog blocks |
| GND | Ground reference | Dedicated analog/digital ground return; requires low-impedance PCB connection to minimize noise coupling |
| SENTOUT | SENT output signal | Open-drain SENT waveform output (3.3 V logic level); requires external pull-up to VDD |

Equivalent & Alternatives
The following parts are listed as comparable options for similar turbo manifold pressure and temperature sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7025DP | Analog ratiometric output (0.2–4.7 V), no integrated NTC interface or SENT; requires external ADC and signal conditioning | Lacks digital interface and temperature fusion - needs separate NTC circuit and microcontroller resources | Select when legacy analog architecture exists and SENT integration is not required |
| KP274E2616XTMA1 | Same package and pinout, but SENT-only output (no NTCIN pin or temperature interface); 12-bit pressure only | Cannot acquire external temperature - unsuitable for pressure+temperature fusion use cases | Select only if temperature is measured elsewhere or not needed in same location |
Compared with MPXV7025DP and KP274E2616XTMA1, the KP275E2616XTMA1 uniquely combines SENT-based digital communication, integrated NTC signal conditioning, and dual 12-bit resolution - enabling single-point pressure-temperature acquisition with reduced system-level complexity and improved diagnostic coverage.

FAQ
What is the SENT frame structure used by KP275E2616XTMA1?
The KP275E2616XTMA1 transmits a 4-nibble SENT frame containing 12-bit pressure data (nibbles 1–3), 12-bit temperature data (nibble 4, MSB), and status bits (nibble 4, LSB). Frame repetition rate is typically 100 Hz, configurable via EEPROM settings. No header or CRC nibbles are included - the device follows SENT rev 4.0 basic format with fixed message length.
Does KP275E2616XTMA1 require external calibration components?
No external calibration components are required. All calibration coefficients - including pressure offset/gain, temperature compensation, and NTC linearization parameters - are stored in on-chip EEPROM and applied automatically during operation. The device ships pre-calibrated; only system-level verification against known pressure/temperature references is recommended during ECU integration.
Can KP275E2616XTMA1 operate without an external NTC sensor?
Yes - the device functions as a standalone pressure sensor even with NTCIN left unconnected. In this mode, SENT output reports valid pressure data and flags NTC open-circuit in status bits. Temperature output defaults to a safe fixed value (e.g., 25 °C) or disables depending on EEPROM configuration, preserving pressure functionality in fault-tolerant designs.
What is the maximum allowable NTC resistance range supported on NTCIN?
The NTCIN pin supports standard automotive NTC thermistors with resistance ranging from 2.2 kΩ to 33 kΩ at 25 °C. The internal bias current and ADC range accommodate corresponding resistance values across −50 °C to +170 °C, with optimal accuracy achieved using 10 kΩ NTCs matching the factory calibration profile.
