**Texas Instruments** · Temperature Sensors · MSOP-10

TMP432ADGST from Texas Instruments, in a MSOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | V+ | power_in | Power supply input, 2.7 V to 5.5 V nominal |
| 2 | DXP1 | input | Analog positive connection for remote temperature sensor channel 1 |
| 3 | DXN1 | input | Analog negative connection for remote temperature sensor channel 1 |
| 4 | DXP2 | input | Analog positive connection for remote temperature sensor channel 2 |
| 5 | DXN2 | input | Analog negative connection for remote temperature sensor channel 2 |
| 6 | GND | power_in | Ground reference point |
| 7 | THERM | output | Digital thermal flag output, active low, open-drain, requires external pullup resistor to V+ |
| 8 | ALERT/THERM2 | output | Digital alert output (reconfigurable as second thermal flag), active low, open-drain, requires external pullup resistor to V+ |
| 9 | SDA | bidirectional | SMBus serial data line, bidirectional, open-drain, requires external pullup resistor to V+ |
| 10 | SCL | input | SMBus serial clock line, open-drain, requires external pullup resistor to V+ |

## CAD (KiCad official)

- Symbol: `TMP432ADGST`
- Footprint: `Package_SO:MSOP-10_3x3mm_P0.5mm`
- 3D model: MSOP-10 (KiCad packages3D, STEP)
- 3D model files: `tmp432adgst-etched.step` / `tmp432adgst-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tmp432adgst.step` / `tmp432adgst.glb` are the bare package body.
