# TMP100NA

**Texas Instruments** · Temperature and Humidity Sensor · SOT-23-6

TMP100NA from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCL | input | Serial clock input for the I2C/SMBus/Two-Wire interface. Open-drain; requires an external pullup resistor to V+. Supports fast mode (400 kHz) and high-speed mode (up to 2 MHz). |
| 2 | GND | power_in | Ground reference. Also serves as the primary thermal path since it is directly connected to the metal lead frame. |
| 3 | ADD1 | input | Address select pin 1. Connect to GND, V+, or leave floating to set one of three logic levels used to encode the I2C slave address. Sampled at power-up and latched. |
| 4 | V+ | power_in | Positive supply voltage input, 2.7 V to 5.5 V. Absolute maximum 7.5 V. |
| 5 | ADD0 | input | Address select pin 0. Connect to GND, V+, or leave floating to set one of three logic levels used to encode the I2C slave address. Sampled at power-up and latched. |
| 6 | SDA | bidirectional | Serial data line for the I2C/SMBus/Two-Wire interface. Open-drain output; requires an external pullup resistor to V+. |

## CAD (KiCad official)

- Symbol: `TMP100NA`
- Footprint: `Package_TO_SOT_SMD:SOT-23-6`
- 3D model: SOT-23-6 (KiCad packages3D, STEP)
- 3D model files: `tmp100na-etched.step` / `tmp100na-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tmp100na.step` / `tmp100na.glb` are the bare package body.
