TMP100 I2C Temperature Sensor

@@ -0,0 +1,48 @@+# TMP100++**Texas Instruments** · Temperature Sensor · SOT-23-6++The TMP100 is a digital temperature sensor with an I2C interface and up to 12-bit (0.0625 C) resolution. Two address pins let several sensors share one bus. It reports temperature directly with +-2 C accuracy over its range, suiting thermal monitoring and management in a compact SOT-23-6.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | SCL | input | I2C/SMBus serial clock input. Open-drain; requires an external pull-up resistor to V+. Supports Fast Mode (up to 400 kHz) and High-Speed Mode (up to 3.4 MHz). |+| 2 | GND | power_in | Ground reference for the device. Connect to the system ground plane. |+| 3 | ADD1 | input | Address-select input 1. Tie to GND, V+, or leave floating to set one of the tri-state address bits, allowing up to eight TMP100 devices on the same I2C bus. |+| 4 | V+ | power_in | Positive supply voltage input. Operating range 2.7 V to 5.5 V; absolute maximum 7.5 V. Bypass with a 0.1 µF ceramic capacitor to GND close to the pin. |+| 5 | ADD0 | input | Address-select input 0. Tie to GND, V+, or leave floating to set one of the tri-state address bits used to program the I2C slave address. |+| 6 | SDA | bidirectional | I2C/SMBus serial data line. Open-drain; requires an external pull-up resistor to V+. Low-level output voltage 0.15 V typ at I_OL = 3 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Digital I2C temperature sensor |+| Resolution | 9 to 12-bit (selectable) |+| Accuracy | +-2 C (-25 to 85 C) |+| Interface | I2C / SMBus |+| Addressing | 2 address pins |+| Supply voltage | 2.7 V to 5.5 V |+| Operating temperature | -55 C to 125 C |++## Ordering variants++- `TMP100DBV`++## CAD (KiCad official)++- Symbol: `tmp100.kicad_sym`+- Footprint: `tmp100.kicad_mod`+- 3D model: SOT-23-6 body from KiCad `Package_TO_SOT_SMD/SOT-23-6`.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tmp100.pdf) (31 pp, sha256 `4099b7e562d93331`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
