# TPS2066CD

**Texas Instruments** · Power Distribution Switches · SOIC-8

TPS2066CD 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 | GND | power_in | Ground connection. |
| 2 | IN | power_in | Input voltage and power-switch drain; connect a 0.1 µF or greater ceramic capacitor from IN to GND close to the IC. |
| 3 | EN1 | input | Enable input channel 1, logic high turns on power switch. |
| 4 | EN2 | input | Enable input channel 2, logic high turns on power switch. |
| 5 | FLT2 | output | Active-low open-drain output, asserted during overcurrent or overtemperature conditions on channel 2. |
| 6 | OUT2 | output | Power-switch output channel 2, connected to load. |
| 7 | OUT1 | output | Power-switch output channel 1, connected to load. |
| 8 | FLT1 | output | Active-low open-drain output, asserted during overcurrent or overtemperature conditions on channel 1. |

## CAD (KiCad official)

- Symbol: `TPS2066CD`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `tps2066cd-etched.step` / `tps2066cd-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps2066cd.step` / `tps2066cd.glb` are the bare package body.
