@@ -0,0 +1,50 @@+# TMP102++**Texas Instruments** · I2C digital temperature sensor · SOT-563++A tiny digital temperature sensor with an I2C interface, in a 6-pin SOT-563 barely larger than an 0805. It reports temperature as a 12-bit value (0.0625 C resolution) with plus/minus 0.5 C accuracy and no calibration, so it feeds a microcontroller directly over two wires. A programmable ALERT output flags an over/under-temperature threshold for thermostat-style control, and the ADD0 pin selects one of four I2C addresses so several share the bus. It sips power (a few microamps averaged) which suits battery designs. Runs 1.4-3.6 V.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | SCL | input | Serial clock input for the SMBus / two-wire / I2C interface. Requires an external pullup resistor (typ. 5 kΩ). Input high 0.7×V+ min, input low 0.3×V+ max; supports Fast mode (up to 400 kHz) and High-speed mode (up to 2.85 MHz). |+| 2 | GND | power_in | Ground reference for the device. Return path for supply and digital I/O. |+| 3 | ALERT | output | Overtemperature alert output. Open-drain, requires an external pullup resistor. VOL ≤ 0.4 V at IOL = 3 mA (V+ > 2 V). Voltage on ALERT must not exceed V+ + 0.3 V and ≤ 4 V. |+| 4 | ADD0 | input | Address-select input. Connect to GND, V+, SDA, or SCL to select one of four unique I2C slave addresses, allowing up to four TMP102 devices on the same bus. |+| 5 | V+ | power_in | Positive supply voltage input, 1.4 V to 3.6 V (3.3 V nominal). Typical quiescent current 7.5 µA (serial bus inactive). Bypass with a 0.01 µF capacitor to GND at the pin. |+| 6 | SDA | bidirectional | Serial data line for the SMBus / two-wire / I2C interface. Open-drain output; requires an external pullup resistor (typ. 5 kΩ). VOL ≤ 0.4 V at IOL = 3 mA (V+ > 2 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Type | I2C digital temperature sensor |+| Resolution | 12-bit (0.0625 °C) |+| Accuracy | ±0.5 °C (-25 to +85 °C) |+| Interface | I2C (SMBus), up to 3.4 MHz |+| Addresses | 4 (via ADD0 pin) |+| Alert | programmable ALERT output |+| Supply voltage | 1.4-3.6 V |+| Package | SOT-563 (6-pin) |++## Ordering variants++- `TMP102AIDRLR (SOT-563)`+- `TMP102AIDRLT (SOT-563, small reel)`++## CAD (KiCad official)++- Symbol: `Sensor_Temperature:TMP102xxDRL`+- Footprint: `Package_TO_SOT_SMD:SOT-563`+- 3D model: SOT-563 (KiCad packages3D)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tmp102.pdf) (33 pp, sha256 `c9da6620ef95f75c`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
