Product details
Overview
KP276D1201 from Infineon is a digital absolute pressure sensor IC based on capacitive sensing, featuring SENT (SAE J2716 rev. 2016) output, integrated NTC temperature interface, ±0.77% FSS pressure accuracy, real 12-bit pressure and temperature resolution, and AEC-Q100 qualification for automotive manifold air pressure (MAP) measurement.
For engineers reviewing the KP276D1201 datasheet, KP276D1201 pinout, KP276D1201 application, or KP276D1201 equivalent, this device delivers calibrated digital pressure/temperature data over SENT with built-in diagnostics, media-robust SMD packaging, and support for external NTC linearization - critical for engine control unit (ECU) integration and functional safety validation.
Technical Context
The KP276D1201 implements a monolithic BiCMOS signal conditioning circuit with dual-channel digitization: one path for internal capacitive pressure sensing (linear transfer function, clamped 1–4088 LSB), and another for external NTC voltage conditioning (12-bit digitized, calibrated via ST = 8.0 LSB/°C and offsT = 585.2 LSB). Both channels feed into a digital core supporting normal and diagnostic modes triggered at power-on.
Its SENT interface operates in enhanced serial message format with synchronization pulse, status nibble, and fast-channel transmission of full 12-bit pressure and temperature codes per frame. 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 | 10–400 kPa absolute; supports full MAP range for gasoline/diesel intake manifolds. |
| Pressure Accuracy | ±0.77% FSS over −40°C to +150°C; enables high-fidelity air mass calculation in ECU models. |
| Output Resolution | Real 12-bit for both pressure and temperature; delivers 4088 distinct pressure codes (1–4088 LSB). |
| SENT Protocol | SAE J2716 rev. April 2016 compliant; supports fast-channel dual-data frames and slow-channel diagnostic nibbles. |
| NTC Interface | Dedicated NTCIN pin with internal buffer amplifier and linearization; accepts standard automotive NTCs (e.g., 10 kΩ @ 25°C). |
| Operating Temp | −40°C to +170°C ambient; qualified per AEC-Q100 Grade 0; enables under-hood deployment. |
| Supply Voltage | 4.5–5.5 V; integrated voltage regulator ensures stable analog/digital domain operation. |
Pinout & Package
Package: PG-DSOF-8-162 - green, media-robust, surface-mount housing with 8-pin SOIC footprint and exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 NCS | Not-Chip-Select (active-low) | Enables SPI communication during calibration only; must be left floating in production use. |
| 2 CLK | Serial Clock | External clock input for SPI interface; unused in SENT operational mode. |
| 3 SDI | Serial Data In | Calibration data input pin; no functional role during SENT operation. |
| 4 SDO | Serial Data Out | Tri-state SPI output; inactive when NCS is high or during normal SENT operation. |
| 5 VDD | Supply Voltage | Primary 4.5–5.5 V power rail; powers internal regulator, ADC, and SENT driver. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5700A | Analog ratiometric output (0.2–4.8 V), no SENT or NTC interface; ±2% FSS accuracy; no AEC-Q100 qualification. | Lacks digital protocol support and integrated diagnostics; requires external ADC and temperature compensation. | Select when cost-sensitive non-automotive industrial designs prioritize analog simplicity over functional safety features. |
| BMP580 | I²C/SPI digital interface, ±0.12 hPa pressure accuracy, but no SENT output, no NTC interface, and not AEC-Q100 qualified. | Targeted at consumer IoT; lacks automotive-grade robustness, media resistance, and SENT compatibility for ECU integration. | Choose for battery-powered portable devices where ultra-low power and high-resolution barometric sensing outweigh protocol and qualification needs. |
Compared with MPX5700A and BMP580, the KP276D1201 uniquely combines SENT protocol compliance, AEC-Q100 Grade 0 qualification, integrated NTC interface, and on-chip diagnostics - making it the only drop-in solution for ASIL-B–capable engine control modules requiring validated digital pressure/temperature fusion.

FAQ
What is the SENT configuration string for KP276D1201?
The device uses SENT2016-03.0us-6dn-ppc(282.0)-esp-A.5: nominal 3.0 µs clock tick, 6 data nibbles, primary pressure code (PPC) with 282.0 kPa reference, enhanced serial protocol (ESP), and A.5 checksum variant. This matches SAE J2716 April 2016 revision for deterministic ECU decoding.
Can the KP276D1201 operate without an external NTC?
Yes - the NTCIN pin may be left unconnected or tied to GND; the device will still output valid 12-bit pressure data via SENTOUT. Temperature reporting will be disabled, but pressure accuracy and diagnostics remain fully functional per AEC-Q100 test plan.
How is pressure clamping implemented in the KP276D1201?
Internal clamping limits pressure output to 1 LSB (10 kPa) at low end and 4088 LSB (400 kPa) at high end. This prevents erroneous readings outside the calibrated range and provides explicit out-of-range indication to the host ECU via fixed-code boundaries.
Are the SPI pins required for normal operation?
No - NCS, CLK, SDI, and SDO are exclusively for factory calibration and test. Infineon recommends leaving them floating in end applications; they have no effect on SENT output, diagnostics, or NTC functionality during powered operation.
