Product details
Overview
P3T1750DP/Q900Z from NXP Semiconductors is an AEC-Q100 qualified digital temperature sensor with I3C and I2C interfaces, ±1 °C accuracy across −40 °C to +125 °C, 12-bit resolution (0.0625 °C), and programmable overtemperature alert functionality. It serves as a system-level thermal monitor in automotive ECUs, SSDs, and industrial controllers requiring high-reliability ambient sensing.
For engineers reviewing the P3T1750DP/Q900Z datasheet, P3T1750DP/Q900Z pinout, P3T1750DP/Q900Z application, or P3T1750DP/Q900Z equivalent, this device delivers dual-bus interoperability (I3C up to 12.5 MHz / I2C up to 3.4 MHz), IBI-capable interrupt signaling without dedicated pins, and automotive-grade qualification under AEC-Q100 Grade 2.
Technical Context
The P3T1750DP/Q900Z integrates an on-chip bandgap temperature sensor with 12-bit successive-approximation ADC, storing results in a read-only Temp register. Its configuration register supports one-shot, continuous, or shutdown operation modes - enabling precise power-state control in battery-sensitive applications.
I3C implementation complies with MIPI I3C SDR specification: it supports dynamic address assignment via SETDASA/ENTDAA CCCs, responds to GETPID/GETBCR/GETDCR commands, and asserts In-Band Interrupts using its open-drain ALERT pin without external hardware. I2C interface supports 32 target addresses and SMBus Alert protocol with THIGH/TLOW limit registers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital temperature sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTS22H | Single I2C interface (up to 1 MHz); ±0.5 °C accuracy (−20 °C to +85 °C); no I3C or AEC-Q100 qualification. | Limited to commercial-grade computing and consumer IoT; unsuitable for automotive or extended-temperature industrial use. | Select when cost sensitivity outweighs interface flexibility and automotive compliance requirements. |
| MAX31875 | I2C-only (up to 3.4 MHz); ±1 °C accuracy (−55 °C to +125 °C); integrated 12-bit ADC but no IBI or dynamic addressing. | Supports wider cold-range operation but lacks I3C features and automotive qualification; used in test equipment and instrumentation. | Choose for legacy I2C-only systems needing broader low-temperature coverage, not for I3C migration or automotive deployment. |
Compared with STTS22H and MAX31875, the P3T1750DP/Q900Z uniquely combines AEC-Q100 Grade 2 qualification, MIPI I3C SDR compliance with IBI, and dual-bus interoperability - making it the only option qualified for next-generation automotive and high-density server thermal architectures.

FAQ
What is the operating voltage range for P3T1750DP/Q900Z?
The P3T1750DP/Q900Z operates from 1.4 V to 3.6 V. Its power-on reset circuit activates once VCC reaches ≥1.2 V, and full functionality is guaranteed within 20 ms. This wide supply range supports direct integration with 1.8 V and 3.3 V logic domains without level-shifting circuitry - a key advantage in mixed-voltage automotive and server designs where the P3T1750DP/Q900Z is deployed.
Does P3T1750DP/Q900Z support both I2C and I3C protocols simultaneously?
Yes, the P3T1750DP/Q900Z natively supports both I2C Fast-mode Plus (up to 3.4 MHz) and MIPI I3C SDR (up to 12.5 MHz) on the same SDA/SCL pins. The interface mode is determined by the controller-initiated protocol sequence - no hardware reconfiguration or pin strapping is required. This dual-protocol capability allows seamless integration into legacy I2C systems and future I3C-based architectures using the same P3T1750DP/Q900Z footprint and layout.
How does the ALERT pin function in I3C versus I2C mode?
In I2C mode, the ALERT pin operates as an SMBus Alert signal, responding to the 00011001 command with its target address. In I3C mode, the same physical pin supports In-Band Interrupt (IBI) - eliminating the need for a separate interrupt line. When configured for IBI, the P3T1750DP/Q900Z drives its dynamic address onto the bus during arbitration, allowing the controller to identify the source of thermal events without polling - a feature unavailable in pure I2C sensors like the P3T1750DP/Q900Z's alternatives.
What is the meaning of /Q900Z in P3T1750DP/Q900Z?
The /Q900Z suffix denotes AEC-Q100 qualification per Grade 2 (−40 °C to +105 °C ambient), PPAP-ready packaging in static shielding bags (SSB), and automotive-specific traceability. It shares identical electrical specifications and pinout with the commercial-grade P3T1750DP, but undergoes additional stress testing, lot traceability, and documentation per automotive quality standards - confirming that P3T1750DP/Q900Z is certified for use in engine bay, cabin, and chassis control modules.
Can P3T1750DP/Q900Z be used in one-shot conversion mode?
Yes, the P3T1750DP/Q900Z supports one-shot conversion mode via the OS bit in its Configuration register (Conf, pointer 01h). In this mode, a single temperature measurement is triggered on command and completes in <25 ms, after which the device automatically returns to shutdown state - drawing only 4.1 μA. This minimizes self-heating and power consumption in battery-powered applications such as telematics units or wireless sensor nodes where the P3T1750DP/Q900Z provides infrequent but accurate thermal snapshots.
