Product details
Overview
TMP106YZCT from Texas Instruments is a digital temperature sensor IC with two-wire (I²C/SMBus) interface, 9–12-bit user-selectable resolution (0.0625°C at 12-bit), ±2.0°C max accuracy from −25°C to +85°C, and ultra-low quiescent current (50 µA active, 0.1 µA standby). It operates across −40°C to +125°C and is used for thermal protection in battery management and notebook computers.
For engineers reviewing the TMP106YZCT datasheet, TMP106YZCT pinout, TMP106YZCT application, or TMP106YZCT equivalent, key selection considerations include its DSBGA-6 (YZC) package, dual I²C address capability (via A0), SMBus Alert support, programmable thermostat modes, and fault-queue configurable alert triggering.
Technical Context
The TMP106YZCT implements a sigma-delta ADC with on-chip diode temperature sensing, delivering digitized output via an SMBus-compatible two-wire interface. Its internal register architecture includes Temperature, Configuration, THIGH, and TLOW registers, all accessible through an 8-bit pointer register.
It supports both Comparator Mode (ALERT latched until temperature returns below TLOW) and Interrupt Mode (ALERT cleared by register read or SMBus Alert Response), with programmable fault queue (1/2/4/6 consecutive faults) and polarity inversion (active-HIGH/active-LOW ALERT).
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Supply Voltage Range | 2.7 V to 5.5 V - compatible with common logic rails including 3.3 V and 5 V systems |
| Temperature Accuracy | ±2.0°C (max) from −25°C to +85°C - meets tight thermal monitoring requirements in computing and portable devices |
| Resolution | 9–12 bits, user-selectable - enables trade-off between precision (0.0625°C) and conversion speed (27.5 ms to 300 ms) |
| Quiescent Current | 50 µA (active), 0.1 µA (standby) - suitable for battery-powered applications requiring long sleep cycles |
| Interface Protocol | I²C/SMBus-compatible two-wire - supports standard microcontroller peripherals without protocol translation |

Pinout & Package
Package: DSBGA-6 (YZC), 2 × 3 wafer chip-scale package, 1.15 mm × 1.00 mm, bump-side-down mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | SDA | Open-drain serial data line - requires external pull-up; supports fast-mode (400 kHz) and high-speed mode (3.4 MHz) |
| B1 | SCL | Open-drain serial clock line - synchronized with SDA; includes integrated Schmitt trigger and spike suppression |
| C1 | V+ | Positive power supply input - accepts 2.7 V to 5.5 V; no power-up sequencing required |
| A2 | GND | Ground reference - serves as thermal and electrical return path; primary thermal conduction path |
| B2 | ALERT | Open-drain interrupt/alert output - configurable polarity and fault-queue behavior for autonomous thermal event signaling |
| C2 | A0 | I²C address select input - sets LSB of 7-bit slave address (1001000 or 1001001), enabling two devices per bus |
Key Features
| Feature | Design Value |
|---|---|
| Two-wire SMBus-compatible interface | Eliminates need for dedicated ADC or SPI resources; interoperable with existing I²C infrastructure |
| User-selectable 9–12-bit resolution | Enables optimization of measurement precision vs. system latency - e.g., 9-bit for rapid thermal trend detection |
| Programmable ALERT with fault queue | Prevents false triggers from transient noise by requiring 1–6 consecutive out-of-limit readings before asserting ALERT |
| Thermostat modes (Comparator/Interrupt) | Supports both latched overtemperature shutdown (Comparator) and event-driven firmware polling (Interrupt) |
| One-shot conversion in shutdown | Allows single temperature reading with <0.1 µA average current - ideal for wake-on-temperature sensor nodes |
Applications
| Smartphone Battery Thermal Monitoring | Notebook CPU Thermal Throttling |
|---|---|

IC Role / Device Role / Timing Role: Integrated into disposable pump cassette; uses ALERT pin to halt motor if temperature exceeds 42.5°C for ≥4 consecutive samples. Use Value: Meets IEC 60601-1 thermal safety requirements with hardware-level fault detection independent of main controller. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital temperature sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMP117AIRGZR | Higher accuracy (±0.1°C), 16-bit resolution, no A0 address pin, same DSBGA-6 package | Requires single-device-per-bus configuration; better suited for metrology-grade calibration tasks | Select when absolute accuracy outweighs multi-device bus flexibility |
| LM75BIMMX/NOPB | Lower accuracy (±2°C), fixed 9-bit resolution, SOIC-8 package, no ALERT polarity control or fault queue | Lacks SMBus Alert and programmable thermostat modes; limited to basic overtemperature flagging | Select for cost-sensitive, space-tolerant designs where advanced alert logic is unnecessary |
Compared with TMP106YZCT, TMP117AIRGZR offers superior metrological performance but sacrifices dual-address capability, while LM75BIMMX/NOPB provides legacy compatibility at the expense of configurability and thermal responsiveness.

FAQ
What is the operating temperature range of the TMP106YZCT?
The TMP106YZCT is specified to operate from −40°C to +125°C, with extended survival ratings up to −55°C and +127°C. Its accuracy is guaranteed at ±2.0°C maximum from −25°C to +85°C and ±3.0°C maximum across the full −40°C to +125°C range. This makes TMP106YZCT suitable for demanding environments such as automotive cabin modules and industrial motor controllers.
Does the TMP106YZCT require external components for basic operation?
No, the TMP106YZCT requires no external components for core functionality. Pull-up resistors on SDA, SCL, and ALERT are mandatory per I²C/SMBus specifications, but no external capacitor, resistor network, or calibration circuitry is needed. A 0.1 µF bypass capacitor on V+ is recommended but not required for stable operation per the datasheet.
How does the ALERT pin function in Comparator Mode versus Interrupt Mode on the TMP106YZCT?
In Comparator Mode (TM = 0), the TMP106YZCT's ALERT pin remains asserted until temperature falls below TLOW for the programmed number of consecutive faults. In Interrupt Mode (TM = 1), ALERT clears upon any register read or successful SMBus Alert Response, enabling event-driven polling. Both modes support polarity inversion (POL bit) and fault-queue filtering (F1/F0 bits) to suppress noise-induced triggers.
Can the TMP106YZCT be used with a 1.8 V I²C bus?
No - the TMP106YZCT requires a minimum V+ of 2.7 V and specifies VIH ≥ 2.1 V, making it incompatible with 1.8 V logic systems. Its input thresholds are not guaranteed below 2.7 V supply, and attempting 1.8 V operation may result in unreliable communication or failure to acknowledge addresses. For 1.8 V systems, consider the TMP108 or TMP116 families instead of TMP106YZCT.
Is the TMP106YZCT pin-compatible with other devices in the TMP10x family?
Yes - the TMP106YZCT shares identical DSBGA-6 (YZC) pinout and footprint with TMP102, TMP103, and TMP108 variants in the same package. However, register maps, default configurations, and feature sets differ: TMP106YZCT uniquely supports dual I²C addressing (A0), SMBus Alert, and programmable fault queue - features absent in earlier TMP102 revisions.
