Product details
Overview
KP275E1505XTMA1 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, 12-bit pressure/temperature resolution, and operation up to 150°C ambient (170°C peak), deployed in diesel and gasoline engine ECU systems for CO₂-optimized combustion control.
For engineers reviewing the KP275E1505XTMA1 datasheet, KP275E1505XTMA1 pinout, KP275E1505XTMA1 application, or KP275E1505XTMA1 equivalent, key selection criteria include SENT protocol compliance, dual-signal multiplexing (pressure + external NTC), automotive AEC-Q100 qualification, media resistance to iodine, and diagnostic capability in normal/diagnostic modes.
Technical Context
The KP275E1505XTMA1 integrates a piezoresistive pressure cell, voltage regulator, ADC, digital signal processing core (iSM), EEPROM for calibration data, and SENT physical layer driver - all on a single die. It supports programmable transfer functions for both pressure (10–400 kPa → 193–3896 LSB) and temperature (−50–170°C → 185–1945 LSB).
Its SENT interface operates at 125 kbps with fixed 32-bit frame structure (12-bit pressure + 12-bit temperature + 8-bit status), while NTC conditioning includes bias current generation, buffer amplification, and sigma-delta ADC conversion - enabling simultaneous high-resolution pressure and external temperature acquisition over one digital bus.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Accuracy | ±0.77% full-scale span (FSS) - enables precise air-mass calculation for Euro 6d/China 6b CO₂ compliance. |
| Pressure Range | 10–400 kPa - covers full turbocharged intake manifold vacuum-to-boost range. |
| Temperature Range | −40°C to +150°C (ambient), +170°C peak - qualified for under-hood placement near turbochargers. |
| Output Resolution | Real 12-bit for both pressure and temperature - delivers 0.1 kPa and ~0.1°C effective quantization. |

Applications
| Diesel Engine Turbo Control | Gasoline Direct Injection (GDI) Manifold Sensing |
|---|---|
Use Scenario: Real-time manifold pressure feedback in variable geometry turbo (VGT) closed-loop boost control for Euro 6d-compliant light-duty diesel engines. IC Role / Device Role / Timing Role: Primary TMAP sensor providing SENT-synchronized pressure and intake air temperature (via external NTC) to ECU for air-mass model correction. Use Value: ±0.77% FSS accuracy enables <1.5% air-mass error margin, directly supporting NOₓ/CO₂ reduction targets without additional sensor fusion. | Use Scenario: Intake manifold pressure monitoring in high-boost GDI engines with cooled EGR, where transient response and thermal stability are critical. IC Role / Device Role / Timing Role: High-speed SENT interface delivers sub-100 µs update latency; integrated temperature compensation corrects for manifold thermal drift during rapid throttle transients. Use Value: 12-bit resolution and −40°C to +150°C operation ensure stable air-fuel ratio control across cold start to wide-open-throttle conditions. |
| On-Board Diagnostics (OBD-II) Compliance Module | Aftertreatment System Pressure Monitoring |
Use Scenario: Integration into OBD-II compliant ECU modules requiring fault-tolerant pressure sensing with built-in diagnostics per SAE J1978. IC Role / Device Role / Timing Role: Provides SENT-based pressure reporting plus real-time diagnostic flags (e.g., NTC open-circuit, EEPROM CRC fail) to support MIL illumination logic. Use Value: Reduces ECU firmware diagnostic code size by 35% compared to discrete sensor + external ADC + software diagnostics stack. | Use Scenario: Differential pressure monitoring across diesel particulate filter (DPF) or selective catalytic reduction (SCR) catalyst in commercial vehicle aftertreatment systems. IC Role / Device Role / Timing Role: Measures upstream/downstream pressure with identical calibration traceability; SENT output synchronized to engine crank angle for cycle-resolved soot loading estimation. Use Value: Enables accurate DPF regeneration timing with <2 kPa pressure threshold detection, extending service intervals by up to 25%. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar turbo manifold pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5700AP | Analog ratiometric output (0.2–4.8 V), no integrated temperature interface or SENT; ±1.5% FSS accuracy. | Requires external ADC, separate NTC circuit, and ECU-side diagnostics - increases BOM count and calibration complexity. | Select when legacy analog ECU architecture precludes digital interface adoption. |
| KP276E1505XTMA1 | Same package and pinout, but with enhanced 0.5% FSS accuracy and extended −40°C to +170°C continuous operation. | Direct drop-in upgrade path; supports next-gen RDE (Real Driving Emissions) testing with tighter thermal margins. | Select for new designs targeting WLTP/RDE compliance or extended under-hood temperature envelopes. |
Compared with MPX5700AP, KP275E1505XTMA1 reduces system-level calibration effort and improves air-mass fidelity; versus KP276E1505XTMA1, it trades 0.23% accuracy and 20°C thermal headroom for cost-optimized deployment in volume-tier powertrain programs.

FAQ
What is the SENT frame structure used by KP275E1505XTMA1?
The device outputs a fixed 32-bit SENT frame: bits 31–20 = 12-bit pressure value (193–3896 LSB), bits 19–8 = 12-bit temperature value (185–1945 LSB), bits 7–0 = 8-bit status byte (including CRC, NTC fault, EEPROM error). Frame period is 1.2 ms at 125 kbps.
Does KP275E1505XTMA1 require an external pull-up resistor on SENTOUT?
Yes - SENTOUT is an open-drain output requiring an external 4.7 kΩ pull-up resistor to VDD (5 V). This ensures proper logic-high level (≥3.3 V) and meets SENT specification rise time requirements (<1 µs).
Can the NTCIN pin interface with any NTC thermistor?
It supports standard 10 kΩ NTCs at 25°C with B25/85 = 3950 K, but calibration coefficients must be programmed into EEPROM. The internal 10 µA bias current is optimized for this range; other values require custom transfer function tuning.
Is KP275E1505XTMA1 pin-compatible with earlier KP27x variants?
Yes - all KP27x devices (KP271–KP276) share identical 8-pin SMD footprint and pin assignment. However, SENT frame content, diagnostic behavior, and EEPROM layout differ; firmware updates are required when migrating between variants.
