Product details
Overview
KP276D1505 from Infineon is a digital absolute pressure sensor IC based on capacitive micromachining, delivering 12-bit pressure and temperature resolution via SENT (SAE J2716 rev. 2016), with ±1.03% FSS accuracy and integrated NTC interface for external temperature sensing - deployed in automotive manifold air pressure (MAP) measurement systems.
For engineers reviewing the KP276D1505 datasheet, KP276D1505 pinout, KP276D1505 application, or KP276D1505 equivalent, this page provides verified functional context, SENT timing parameters, diagnostic behavior, NTC linearization support, and AEC-Q100-qualified packaging details essential for ECU sensor integration and industrial pressure monitoring design.
Technical Context
The KP276D1505 implements a monolithic BiCMOS signal conditioning circuit with dual-channel digitization: pressure sensed by capacitive cells is converted to a 12-bit output (1–4088 LSB, 10–300 kPa range), while external NTC voltage is conditioned, linearized, and digitized to a second 12-bit value (265–1945 LSB, −40 to +170 °C). Both values are transmitted per SENT frame.
Its SENT interface operates in enhanced serial message format with synchronization pulse, status nibble, and fast-channel data pulses; diagnostics include EEPROM check, signal-out-of-range detection, and self-test triggered at power-on. SPI pins (NCS/CLK/SDI/SDO) are reserved for calibration only and must be left floating in application circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 10–300 kPa absolute - covers full MAP operating range for gasoline and turbocharged engines. |
| Pressure Accuracy | ±1.03% FSS at 25 °C - enables high-fidelity air mass calculation without post-assembly trimming. |
| Resolution | Real 12-bit for both pressure and temperature - delivers 0.073 kPa and 0.125 °C effective quantization steps. |
| SENT Protocol | SAE J2716 rev. Apr 2016 compliant - supports deterministic latency (≤1.5 ms frame time) and diagnostic nibble reporting. |
| NTC Interface | Dedicated NTCIN pin with internal buffer amplifier and linearization - eliminates need for external ADC or lookup tables. |
| Operating Temp | −40 to +150 °C ambient - qualified per AEC-Q100 Grade 0, enabling under-hood deployment. |
| Supply Voltage | 4.5–5.5 V - compatible with standard automotive 5 V rail and robust against battery transients. |
Pinout & Package
Package: PG-DSOF-8-162 - green, media-robust surface-mount housing with 8-pin SOIC footprint and exposed thermal pad (non-electrical).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 NCS | Not-Chip-Select (active-low) | Enables SPI communication only during factory calibration; must be left floating in end application. |
| 2 CLK | Serial Clock Input | External clock source for SPI interface; unused in normal SENT operation. |
| 3 SDI | Serial Data In | Calibration data input path; no functional role in SENT mode. |
| 4 SDO | Serial Data Out | Tri-state SPI output; inactive during SENT transmission. |
| 5 VDD | Power Supply | Primary 4.5–5.5 V supply for analog/digital core and SENT driver. |
| 6 SENTOUT | SENT Output Signal | Open-drain CMOS output driving SENT waveform (3.8 V VOH, 1.1 V VOL) to ECU receiver. |
| 7 NTCIN | NTC Sensor Input | Analog input for external NTC; includes internal bias current and programmable gain for linearization. |
| 8 GND | Ground Reference | Common return for analog/digital domains and SENT output stage. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Diagnostic Mode | Self-test of pressure cell integrity and signal path triggered at power-on - reduces need for external test infrastructure. |
| Media-Robust Housing | PG-DSOF-8 package qualified for direct exposure to engine oil, fuel vapor, and brake fluid - eliminates need for protective gel or isolation membranes. |
| SENT Fast+Slow Channel | Full 12-bit pressure + 12-bit NTC data in every SENT frame (fast channel), plus diagnostic status across multiple frames (slow channel) - enables real-time fault logging without protocol overhead. |
| BiCMOS Signal Conditioning | Monolithic integration of capacitive sensing element and mixed-signal ASIC - ensures matched temperature drift and eliminates inter-die calibration errors. |
| NTC Linearization Engine | On-chip polynomial compensation using ST = 8.0 LSB/°C and offsT = 585.2 LSB - removes software linearization burden from host MCU. |
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 |
|---|---|---|---|
| MPX5700AC6U | Analog ratiometric output (0.2–4.8 V), no SENT or NTC interface, ±2.0% FSS accuracy. | Requires external ADC, separate temperature sensor, and custom firmware for diagnostics. | Select when legacy analog interface is mandated and cost sensitivity outweighs diagnostic capability. |
| BMP388 | I²C digital interface, 20-bit pressure resolution, no SENT or NTC support, ±0.06 hPa typical accuracy. | Targeted at consumer drones and wearables; lacks AEC-Q100 qualification and media resistance. | Select for high-resolution barometric sensing where automotive reliability and fluid compatibility are not required. |
Compared with MPX5700AC6U and BMP388, the KP276D1505 uniquely combines SENT protocol compliance, integrated NTC processing, AEC-Q100 qualification, and media-robust packaging - making it the only drop-in solution for next-generation automotive MAP and industrial pressure nodes requiring zero-additional-diagnostic firmware.

FAQ
What is the SENT frame structure used by KP276D1505?
The KP276D1505 transmits SENT frames per SAE J2716 rev. 2016, starting with a sync pulse, followed by a status nibble, then 12-bit pressure and 12-bit NTC data in fast-channel nibbles. Frame duration is ≤1.5 ms, with nominal tick period of 3.0 µs and clamped output codes (1–4088 for pressure, 265–1945 for temperature).
Can the SPI pins (NCS/CLK/SDI/SDO) be used in production systems?
No - pins 1–4 are exclusively for factory calibration and test. Infineon specifies they must remain unconnected (floating) in end applications; any connection risks undefined behavior, SENT disruption, or damage to internal protection circuits during normal operation.
How does the KP276D1505 handle external NTC sensor nonlinearity?
It applies on-chip linearization using pre-programmed coefficients: Tamb = (outT − 585.2) / 8.0, where outT is the 12-bit digitized NTC value. This eliminates host MCU computation and supports NTCs with β-values between 3435 K and 3984 K without external lookup tables.
Is the KP276D1505 compatible with existing SENT receivers designed for other Infineon sensors?
Yes - its SENT2016-03.0us-6dn-ppc(282.0)-esp-A.5 configuration matches timing and framing conventions used across Infineon's SENT pressure portfolio, including KP276D1505 and KP276D1506, ensuring interoperability with standard automotive SENT decoders.
