Product details
Overview
P3T1755DP/0900Z from NXP Semiconductors is an AEC-Q100 qualified digital temperature sensor with I3C and I²C interfaces, ±0.5 °C accuracy from −20 °C to +85 °C, 12-bit resolution (0.0625 °C), and programmable overtemperature alert functionality - deployed in automotive powertrain and ADAS modules for real-time thermal monitoring.
For engineers reviewing the P3T1755DP/0900Z datasheet, P3T1755DP/0900Z pinout, P3T1755DP/0900Z application, or P3T1755DP/0900Z equivalent, this page delivers verified interface timing (I3C up to 12.5 MHz, I²C up to 3.4 MHz), TSSOP8 package mapping, automotive-grade supply range (1.4–3.6 V), alert configuration modes, and validated alternative part comparisons.
Technical Context
The P3T1755DP/0900Z integrates an on-chip bandgap temperature sensor with 12-bit successive-approximation ADC, storing results in a read-only Temp register updated at configurable conversion rates. Its dual-interface architecture supports I3C SDR target mode with In-Band Interrupt (IBI) capability and Fast-mode Plus I²C with 32 selectable target addresses.
Configuration is managed via four accessible registers (Conf, TLOW, THIGH, Temp) using pointer-based addressing; the Conf register controls one-shot/continuous/shutdown modes, while alert behavior (comparator vs. interrupt mode, active-HIGH/LOW polarity, fault queue depth) is fully programmable through TLOW/THIGH thresholds and dedicated control bits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital temperature sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTS22HTR | I²C-only interface (no I3C), ±0.5 °C accuracy, same TSSOP8 package, 1.7–3.6 V supply | Lacks IBI and dynamic addressing; suitable for cost-sensitive I²C-only designs without multi-sensor arbitration needs | Select STTS22HTR only if I3C features are unnecessary and supply voltage >1.7 V is guaranteed |
| MAX31875R2+ | I²C interface, ±0.25 °C accuracy, 1.7–3.6 V, 3 μA shutdown current, but no automotive qualification | Higher accuracy but unqualified for automotive use; lacks AEC-Q100 validation and extended temp range support | Choose MAX31875R2+ only for non-automotive industrial applications requiring tighter tolerance |
Compared with STTS22HTR and MAX31875R2+, the P3T1755DP/0900Z uniquely combines AEC-Q100 qualification, dual I3C/I²C support with IBI, and guaranteed ±0.5 °C accuracy down to 1.4 V - making it the only option for next-gen automotive sensor hubs requiring scalable, interrupt-efficient thermal monitoring.

FAQ
What is the operating temperature range of the P3T1755DP/0900Z?
The P3T1755DP/0900Z operates from −40 °C to +125 °C, meeting AEC-Q100 Grade 2 requirements. Its ±0.5 °C accuracy is specified from −20 °C to +85 °C, and ±1 °C accuracy applies across the full range. This makes the P3T1755DP/0900Z suitable for under-hood automotive environments where thermal extremes demand robust performance without calibration drift.
Does the P3T1755DP/0900Z support both I3C and I2C interfaces simultaneously?
Yes, the P3T1755DP/0900Z supports concurrent I3C and I²C operation on the same SDA/SCL pins. The interface mode is auto-detected: I3C communication initiates upon receipt of MIPI I3C Common Command Codes (e.g., SETDASA), while standard I²C START conditions engage I²C protocol. No hardware reconfiguration or pin muxing is required to switch between protocols.
How does the ALERT pin function in I3C mode compared to I2C mode for the P3T1755DP/0900Z?
In I²C mode, the ALERT pin operates as an SMBus-compatible open-drain alert signal that responds to the SMBus alert command (00011001). In I3C mode, the P3T1755DP/0900Z uses In-Band Interrupt (IBI) instead - eliminating the need for the ALERT pin entirely. IBI allows the device to assert its dynamic address directly on the SDA line during bus idle periods, reducing pin count and PCB complexity.
What package type and footprint does the P3T1755DP/0900Z use?
The P3T1755DP/0900Z uses the TSSOP8 package (SOT505-1): plastic thin shrink small outline, 8 leads, 3 mm body width. It is RoHS-compliant and designed for reflow soldering. The pinout matches industry-standard TSSOP8 thermal sensor footprints, enabling drop-in replacement in existing layouts where mechanical and thermal constraints permit.
Can the P3T1755DP/0900Z be used in non-automotive applications?
Yes, the P3T1755DP/0900Z is fully functional in industrial and computing applications such as server thermal management and SSD temperature monitoring. While its AEC-Q100 qualification and −40 °C to +125 °C rating exceed typical commercial requirements, its dual I3C/I²C interface, low quiescent current (4.1 μA), and programmable alert logic provide tangible benefits in any high-density, multi-sensor system requiring scalable thermal visibility.
