Product details
Overview
P3T1750DP from NXP Semiconductors is a digital temperature sensor with I3C and I2C-bus interfaces, ±1 °C accuracy over −40 °C to +125 °C, 12-bit resolution (0.0625 °C), and programmable overtemperature alert functionality. It operates from 1.4 V to 3.6 V and delivers 4.1 μA typical quiescent current, targeting thermal monitoring in space-constrained embedded systems such as SSDs and industrial controllers.
For engineers reviewing the P3T1750DP datasheet, P3T1750DP pinout, P3T1750DP application, or P3T1750DP equivalent, this page provides verified technical context, validated pin functions, real-world use cases, and confirmed alternative options for thermal sensing in I3C/I2C-based designs requiring automotive-grade reliability or high-speed bus compatibility up to 12.5 MHz.
Technical Context
The P3T1750DP integrates an on-chip bandgap temperature sensor and 12-bit ADC to produce two's complement digital output stored in a read-only Temp register. It supports three operating modes-normal, one-shot, and shutdown-configured via OS, TM, and SD bits in the Conf register.
I3C operation includes MIPI I3C SDR target interface with In-Band Interrupt (IBI) capability, dynamic address assignment via SETDASA/ENTDAA CCCs, and BCR/DCR registers identifying it as an I3C target (BCR[7:6] = 00) and temperature sensor (DCR = 0x63). I2C mode supports Fast-mode Plus (3.4 MHz), 32 target addresses, and SMBus Alert protocol with programmable fault queue and polarity.
Key Specifications

Pinout & Package
Package: TSSOP8 (SOT505-1), plastic thin shrink small outline package, 8 leads, 3 mm body width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SDA | Digital I/O | I3C/I2C bidirectional data line - open-drain, requires external pull-up; supports both protocols on shared bus. |
| SCL | Digital input | I3C/I2C serial clock input - synchronizes all register reads/writes and interrupt acknowledgments. |
| ALERT | Open-drain output | Programmable alert signal (comparator or interrupt mode); active HIGH/LOW selectable - eliminates need for dedicated interrupt pin in I3C systems via IBI. |
| GND | Ground reference | Primary return path for analog and digital circuitry - must be low-impedance to maintain ±1 °C accuracy. |
| A2, A1, A0 | Digital inputs | User-defined I2C target address bits - enable up to 32 unique addresses on same bus; sampled once at first valid START condition. |
| VCC | Power supply | 1.4–3.6 V supply input - powers internal bandgap sensor, ADC, and interface logic; POR threshold is 1.2 V. |
Key Features
| Feature | Design Value |
|---|---|
| I3C In-Band Interrupt (IBI) | Eliminates dedicated interrupt pin by allowing P3T1750DP to emit its address on the bus during arbitration - reduces PCB routing complexity and pin count. |
| 32 I2C Target Addresses | Three address pins (A2–A0) support 32 unique I2C addresses - enables scalable thermal monitoring across multi-board or multi-module systems without address conflict. |
| Programmable Alert Modes | Configurable as comparator (latched) or interrupt (pulse) mode with user-selectable polarity - supports both thermal warning and emergency shutdown logic. |
| Dynamic Address Assignment | Supports SETDASA and ENTDAA CCCs - allows runtime reconfiguration of I3C dynamic addresses without hardware changes or reset cycles. |
| Temperature Register Persistence | Temp register retains latest conversion result during read operations - permits concurrent measurement and host access without data loss or timing constraints. |
Applications
| SSD Thermal Management | Industrial PLC Temperature Monitoring |
|---|---|
|
Use Scenario: Real-time die temperature tracking in NVMe SSDs to prevent thermal throttling and extend NAND flash lifetime. IC Role / Device Role / Timing Role: Primary temperature sensor interfacing directly with SSD controller via I3C at 12.5 MHz for sub-20 ms update intervals. Use Value: 0.0625 °C resolution enables precise thermal margining; ±1 °C accuracy ensures consistent throttle activation across temperature gradients. |
Use Scenario: Ambient and component-level temperature supervision in modular industrial PLC backplanes with mixed-voltage I/O modules. IC Role / Device Role / Timing Role: Local sensor node on I2C bus (3.4 MHz Fast-mode Plus), configured in one-shot mode to minimize self-heating during periodic scans. Use Value: 4.1 μA quiescent current prevents localized heating; 32-address support allows daisy-chained deployment across 8+ I/O slots. |
| Automotive Infotainment SoC Monitoring | Server CPU DIMM Slot Sensing |
|
Use Scenario: Junction temperature monitoring of application processors in AEC-Q100-compliant infotainment head units operating from −40 °C to +125 °C. IC Role / Device Role / Timing Role: Secondary thermal sensor connected to SoC's I3C bus, using IBI to notify thermal management firmware without polling overhead. Use Value: IBI reduces bus traffic by >90% vs. polling; AEC-Q100 qualification (P3T1750DP/Q900 variant) validates reliability for automotive duty cycles. |
Use Scenario: Per-DIMM temperature sensing in dual-socket servers to dynamically adjust memory refresh rates and prevent data corruption. IC Role / Device Role / Timing Role: I2C target on DDR5 memory module PCB, reading temperature every 500 ms in normal mode with programmable THIGH/TLOW thresholds. Use Value: Programmable fault queue prevents false alerts from transient spikes; 125 °C max rating covers worst-case DIMM thermal profiles. |
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 (no I3C), 0.5 °C accuracy (−20 °C to +85 °C), 1.7–3.6 V supply, 2.5 μA typical current | Limited to consumer-grade temperature ranges; lacks IBI and dynamic addressing - suitable only where I3C features are unused. | Select when cost sensitivity outweighs I3C feature requirements and full −40 °C to +125 °C range is not needed. |
| MAX31875 | I2C-only, ±0.75 °C accuracy (−55 °C to +150 °C), 1.7–3.6 V, 5 μA typical current, no ALERT pin - uses SMBus Alert command only | Broad temp range but no native I3C or open-drain ALERT output; relies on controller-side SMBus Alert interpretation. | Prefer for ultra-wide-range industrial sensors where I3C is absent and ALERT pin independence is not required. |
Compared with STTS22H and MAX31875, the P3T1750DP uniquely combines I3C IBI, ±1 °C accuracy across automotive grade, and a dedicated open-drain ALERT pin - enabling lower-system-latency thermal response and simplified multi-sensor bus architecture without sacrificing precision or voltage flexibility.

FAQ
What communication interfaces does the P3T1750DP support?
The P3T1750DP supports both I3C (up to 12.5 MHz) and I2C (up to 3.4 MHz) interfaces. It implements full MIPI I3C SDR target functionality including In-Band Interrupt (IBI), dynamic address assignment via SETDASA/ENTDAA CCCs, and standard I2C Fast-mode Plus with 32 configurable target addresses. The P3T1750DP does not support SPI or UART interfaces.
What is the temperature accuracy and operating range of the P3T1750DP?
The P3T1750DP delivers ±1 °C maximum accuracy across its full operating range of −40 °C to +125 °C, specified at supply voltages from 1.4 V to 3.6 V. This accuracy is guaranteed without system-level calibration and applies to both I2C and I3C readout methods. The device uses an on-chip bandgap sensor and 12-bit ADC to achieve this performance.
How does the ALERT pin function on the P3T1750DP?
The ALERT pin on the P3T1750DP is an open-drain output supporting two modes: Alert comparator mode (latched) and Alert interrupt mode (pulse). Its active state (HIGH or LOW) is programmable. In I2C mode, it functions as an SMBus Alert signal; in I3C mode, it is superseded by In-Band Interrupt, eliminating the need for a physical interrupt line. The P3T1750DP uses the ALERT pin only for I2C-based alert signaling.
What package type and pin count does the P3T1750DP use?
The P3T1750DP is housed in a TSSOP8 package (SOT505-1), an 8-lead plastic thin shrink small outline package with 3 mm body width. Pinout includes VCC, GND, SDA, SCL, ALERT, and three address pins (A2, A1, A0). This footprint is compatible with standard reflow processes and supports high-density PCB layouts in space-constrained applications like SSD modules and automotive ECUs.
Does the P3T1750DP support automotive qualification?
The base P3T1750DP is not AEC-Q100 qualified; however, the automotive-grade variant P3T1750DP/Q900 is fully AEC-Q100 compliant and intended for automotive applications. Both share identical electrical specifications, pinout, and functionality, differing only in qualification testing and packaging marking (Q1750 top-side mark). Customers requiring automotive use must specify P3T1750DP/Q900Z for ordering.
