Product details
Overview
TMP110DIDPWR from Texas Instruments is a 5-pin X2SON-packaged I²C/SMBus-compatible digital temperature sensor with ±1.0°C accuracy across –40°C to 125°C, 12-bit resolution (0.0625°C LSB), and dual pinout variants (address or alert). It serves as a system-level thermal monitor in space-constrained, battery-powered applications such as SSDs, industrial PCs, and video doorbells.
For engineers reviewing the TMP110DIDPWR datasheet, TMP110DIDPWR pinout, TMP110DIDPWR application, or TMP110DIDPWR equivalent, key selection criteria include its ultra-small 0.8 × 0.8 mm footprint, 1.14–5.5 V supply range, 3.2 µA average current at 1 Hz, open-drain ALERT/ADD0 flexibility, and software compatibility with TMP102/TMP112.
Technical Context
The TMP110DIDPWR implements a factory-calibrated bandgap-based thermal sensing element with a 12-bit successive-approximation ADC and on-chip oscillator. Its digital core supports both continuous-conversion and one-shot modes, with programmable conversion rates (0.25–8 Hz) and configurable alert thresholds via THigh_Limit/TLow_Limit registers.
It features I²C Fast Mode (400 kHz) and Fast Mode Plus (1 MHz) timing compliance, SMBus Alert Response support, and I³C Mixed Bus co-existence capability. The device uses Q4 (12-bit left-aligned) temperature encoding and provides two distinct pinout variants-TMP110D (ADD0 pin) and TMP110D0–D3 (ALERT pin)-with identical electrical specs and register mapping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Accuracy | ±1.0°C max from –40°C to 125°C at V+ ≥ 1.4 V - enables reliable thermal protection without system-level calibration. |
| Resolution | 12-bit (0.0625°C LSB) - supports fine-grained thermal trending for fan control or throttling decisions. |
| Supply Range | 1.14 V to 5.5 V - interoperates with low-voltage microcontrollers (1.2 V logic) and industrial 3.3/5 V rails. |
| Average Current | 3.2 µA at 1 Hz - extends battery life in always-on environmental sensors (e.g., cold-chain loggers). |
| Active Conversion Time | 10.25–11.25 ms - ensures rapid thermal response for real-time CPU or SSD thermal management. |
| Interface | I²C/SMBus compatible, Fast Mode Plus (1 MHz) - supports high-speed bus sharing in dense multi-sensor systems. |
| Package | X2SON-5 (0.8 mm × 0.8 mm × 0.4 mm) - fits under 1 mm height constraints where DSBGA is unsuitable. |
Pinout & Package
The TMP110DIDPWR uses a 5-pin X2SON package (DPW) with 0.4 mm profile and 0.5 mm pitch. Pin 1 has curved edges per JEDEC MO-302. Two variants exist: Address variant (ADD0 pin) and Alert variant (ALERT pin); TMP110DIDPWR is the Alert variant (ALERT pin, no ADD0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Provides return path for analog/digital circuitry; must be connected to system ground plane for accuracy. |
| SCL | I²C clock input | Accepts standard I²C clock signals up to 1 MHz; requires external pull-up resistor (typically 2.2–10 kΩ). |
| ALERT | Open-drain overtemperature output | Asserts low when temperature exceeds THigh_Limit; requires external pull-up; used for hardware interrupt-driven thermal shutdown. |
| SDA | I²C bidirectional data line | Open-drain I/O; shares bus with other I²C devices; requires external pull-up resistor matching SCL. |
| V+ | Power supply input | Accepts 1.14–5.5 V; internal POR activates above 1.06 V; brownout detect triggers below 0.97 V. |
Key Features
| Feature | Design Value |
|---|---|
| Pinout-flexible 5th terminal | ALERT pin enables hardware-triggered thermal interrupts without MCU polling - reduces firmware overhead in embedded systems. |
| Software compatibility | Register map and command set match TMP102/TMP112 - allows drop-in replacement in existing I²C thermal firmware stacks. |
| Low-power operation | 0.15 µA shutdown current and 3.2 µA average at 1 Hz - supports >10-year battery life in wireless sensor nodes. |
| Extended voltage range | Operates down to 1.14 V - interfaces directly with energy-harvesting power supplies or ultra-low-VDD MCUs. |
| Thermal hysteresis | 0.0625°C - prevents alert chatter near threshold crossings during slow thermal transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital temperature sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMP112DRLR | ±0.5°C accuracy; 6-pin SOT563 (1.6 × 1.6 mm); includes both ADD0 and ALERT pins on same package | Higher accuracy required for precision thermal control loops; larger footprint acceptable | Select TMP112DRLR when ±0.5°C accuracy is mandatory and board space permits 2.56× larger package. |
| TMP102DBVR | ±2.0°C accuracy; 6-pin SOT563; software-compatible but no ALERT pin; lower supply current (10 µA avg @ 1 Hz) | Cost-sensitive, non-critical thermal awareness (e.g., presence detection); no hardware interrupt needed | Choose TMP102DBVR for lowest BOM cost where ±2.0°C tolerance is acceptable and ALERT functionality is unused. |
Compared with TMP110DIDPWR, TMP112DRLR delivers tighter accuracy in a larger package with dual-function pinout, while TMP102DBVR trades accuracy for lower cost and smaller current draw - making TMP110DIDPWR the optimal balance of size, accuracy, and interrupt capability for volume-constrained systems.

FAQ
What is the operating temperature range of the TMP110DIDPWR?
The TMP110DIDPWR operates from –40°C to 125°C. This full industrial range is guaranteed across its entire 1.14 V to 5.5 V supply voltage window and supports deployment in harsh environments such as factory floors, outdoor electronics, and automotive cabin modules. Accuracy remains ±1.0°C across this range when V+ ≥ 1.4 V.
Does the TMP110DIDPWR support I²C Fast Mode Plus?
Yes, the TMP110DIDPWR supports I²C Fast Mode Plus with a maximum SCL frequency of 1 MHz. Its timing parameters - including t(LOW) = 0.5 µs and t(HIGH) = 0.26 µs - comply fully with Fast Mode Plus specifications across –40°C to 125°C and 1.14–5.5 V supply, enabling high-speed bus sharing in multi-sensor systems.
How does the ALERT pin function on the TMP110DIDPWR?
The ALERT pin on the TMP110DIDPWR is an open-drain output that asserts low when temperature exceeds the programmed THigh_Limit. It operates in either comparator mode (latched until temperature falls below TLow_Limit) or alert mode (cleared only by register read or SMBus Alert Response). A pull-up resistor is required, and sink current capability is specified at 3 mA.
Is the TMP110DIDPWR pin-compatible with the TMP102 or TMP112?
No - the TMP110DIDPWR uses a 5-pin X2SON package, while TMP102 and TMP112 use 6-pin SOT563. However, TMP110DIDPWR is software-compatible: register addresses, bit definitions, and I²C command sequences match TMP102/TMP112, enabling reuse of existing driver code with minor pin-mapping adjustments.
What is the temperature resolution and data format of the TMP110DIDPWR?
The TMP110DIDPWR provides 12-bit temperature data in Q4 format (0.0625°C LSB), left-aligned in a 16-bit word. Negative values use two's complement. The default 12-bit mode yields ±128°C range; extended 13-bit mode (via EM bit) doubles the positive range to +256°C while retaining 0.0625°C resolution.
