# LM92CIMX

**Texas Instruments** · Temperature Sensors · SOIC-8

LM92CIMX from Texas Instruments, in a SOIC-8. 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 | SDA | bidirectional | Serial bi-directional data line, open-drain output, driven from the controller. |
| 2 | SCL | input | Serial bus clock input, driven from the controller. |
| 3 | T_CRIT_A | output | Critical temperature alarm open-drain output, active when temperature exceeds the programmable critical limit; connect a pull-up resistor, controller interrupt line or system hardware shutdown (sink current max 10 mA, voltage max 6.5V). |
| 4 | GND | power_in | Power supply ground. |
| 5 | INT | output | Interrupt open-drain output, active when temperature goes outside the programmable window; connect a pull-up resistor or controller interrupt line (sink current max 10 mA, voltage max 6.5V). |
| 6 | A1 | input | User-set address input, tied to ground (low, 0) or +VS (high, 1). |
| 7 | A0 | input | User-set address input, tied to ground (low, 0) or +VS (high, 1). |
| 8 | +VS | power_in | Positive supply voltage input, DC voltage from 2.7V to 5.5V. |

## CAD (KiCad official)

- Symbol: `LM92CIMX`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `lm92cimx-etched.step` / `lm92cimx-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm92cimx.step` / `lm92cimx.glb` are the bare package body.
