Product details
Overview
P3T1755DPZ from NXP Semiconductors is a high-accuracy digital temperature sensor with dual I3C (up to 12.5 MHz) and I2C (up to 3.4 MHz) interfaces, ±0.5 °C accuracy from −20 °C to +85 °C, 12-bit resolution (0.0625 °C), and programmable overtemperature alert functionality - deployed in SSD thermal monitoring, server ambient sensing, and automotive powertrain control.
For engineers reviewing the P3T1755DPZ datasheet, P3T1755DPZ pinout, P3T1755DPZ application, or P3T1755DPZ equivalent, this page delivers verified interface timing, TSSOP8 package mapping, IBI-capable interrupt behavior, and validated automotive-grade alternatives compliant with AEC-Q100.
Technical Context
The P3T1755DPZ integrates an on-chip bandgap temperature sensor with 12-bit ADC conversion, storing results in a read-only Temp register updated every conversion cycle. Its dual-bus architecture supports simultaneous I2C target addressing (32 addresses via A0–A2) and I3C dynamic address assignment via SETDASA/ENTDAA CCCs.
It implements two alert modes - comparator and interrupt - with programmable fault queue depth, THIGH/TLOW thresholds, and polarity selection. The device operates across 1.4 V–3.6 V supply and enters shutdown mode to reduce quiescent current to 4.1 μA typical, while maintaining full register accessibility upon wake.
Key Specifications

Pinout & Package
Package: TSSOP8 (SOT505-1), plastic thin shrink small outline, 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' data framing. |
| SCL | Digital input | I3C/I2C serial clock input; synchronizes all register reads/writes and interrupt acknowledgments. |
| ALERT | Open-drain output | Programmable alert signal; asserts on over/under-temperature events; no dedicated interrupt pin required in I3C mode. |
| GND | Ground reference | Analog and digital ground return; must be connected to system common ground plane for ADC stability. |
| A2, A1, A0 | Digital inputs | User-configurable address bits; define one of 32 unique I2C target addresses (e.g., 1000000b to 1011111b). |
| VCC | Power supply | Primary supply input; powers internal bandgap sensor, ADC, and interface logic; decoupling capacitor required. |
Key Features
| Feature | Design Value |
|---|---|
| In-Band Interrupt (IBI) | Eliminates need for dedicated interrupt pin by allowing P3T1755DPZ to assert its dynamic address directly on the I3C bus during arbitration. |
| Programmable Alert Modes | Supports both comparator (latched) and interrupt (pulse) alert behaviors, configurable via Conf register bit TM. |
| Multi-Protocol Register Access | Same Temp, Conf, TLOW, and THIGH registers accessible identically over I2C and I3C - no firmware porting required. |

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 | I2C-only interface (no I3C), 0.5 °C accuracy, 1.7–3.6 V supply, 3.5 μA shutdown current | Lacks IBI and dynamic addressing; limited to legacy I2C systems without I3C migration path | Select when I3C features are unnecessary and lowest possible quiescent current is prioritized. |
| MAX31875 | I2C interface only, ±0.25 °C accuracy (−20 °C to +85 °C), 1.7–3.6 V supply, 2.5 μA shutdown current | Higher accuracy but no I3C support; alert pin lacks IBI capability; not AEC-Q100 qualified | Select for highest precision in non-automotive, I2C-only designs where I3C scalability is not required. |
Compared with STTS22H and MAX31875, the P3T1755DPZ uniquely delivers I3C-native interrupt handling, automotive qualification, and dual-bus register compatibility - making it the only choice for next-generation scalable thermal sensing in I3C ecosystems requiring AEC-Q100 compliance.

FAQ
What communication protocols does the P3T1755DPZ support?
The P3T1755DPZ supports both I3C (up to 12.5 MHz SDR mode) and I2C (up to 3.4 MHz Fast-mode Plus). It implements full MIPI I3C target functionality including SETDASA, ENTDAA, and IBI, while maintaining full register-level compatibility with standard I2C read/write sequences. The P3T1755DPZ uses identical memory-mapped registers across both interfaces, eliminating firmware rework during protocol migration.
How does the ALERT pin function in I3C versus I2C mode?
In I2C mode, the ALERT pin operates as an SMBus-compatible open-drain interrupt signal that responds to the SMBus alert command (00011001). In I3C mode, the P3T1755DPZ uses In-Band Interrupt (IBI) instead - asserting its dynamic address directly on the bus during arbitration, eliminating the need for a physical ALERT connection. The P3T1755DPZ automatically selects the appropriate behavior based on detected bus protocol.
What is the temperature accuracy specification for P3T1755DPZ across its full operating range?
The P3T1755DPZ guarantees ±0.5 °C maximum accuracy from −20 °C to +85 °C and ±1.0 °C maximum from −40 °C to +125 °C, measured at VCC = 1.4–3.6 V. This specification is tested and guaranteed per NXP's production test flow and applies to the P3T1755DPZ variant shipped in TSSOP8 packaging with SOT505-1 footprint.
Can the P3T1755DPZ operate in low-power shutdown mode while retaining configuration settings?
Yes - the P3T1755DPZ supports shutdown mode with only 4.1 μA typical supply current, and all configuration registers (Conf, TLOW, THIGH) retain their programmed values. Upon wake-up, the device resumes operation using the last stored settings without requiring reinitialization. The P3T1755DPZ achieves this via internal retention circuitry independent of VCC state.
Is the P3T1755DPZ qualified for automotive applications?
Yes - the P3T1755DPZ variant (P3T1755 DP/Q900Z) is AEC-Q100 Grade 2 qualified (−40 °C to +105 °C ambient), with PPAP documentation available through NXP sales. The P3T1755DPZ itself shares identical die, TSSOP8 packaging, and electrical specifications; qualification status is defined by the Q900 suffix and associated test reports, not the base part number alone.
