# TPS2041BD

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

TPS2041BD 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 for the device; the datasheet lists this pin as ground. |
| 2 | IN | power_in | Input voltage to the power switch; recommended operating input range is 2.7 V to 5.5 V and the absolute maximum is -0.3 V to 6 V. |
| 3 | IN | power_in | Input voltage to the power switch (pin 3 is internally tied with pin 2 as a second input pin); recommended operating input range is 2.7 V to 5.5 V. |
| 4 | EN | input | Enable input; logic low turns on the power switch, with a recommended input range of 0 V to 5.5 V. |
| 5 | OC | output | Active-low, open-drain overcurrent output that signals an overcurrent or short-circuit condition; absolute voltage range is -0.3 V to 6 V. |
| 6 | OUT | power_out | Power-switch output; recommended continuous output current is 0 to 500 mA and the absolute maximum output voltage is -0.3 V to 6 V. |
| 7 | OUT | power_out | Power-switch output (pin 7 is internally tied with pins 6 and 8); recommended continuous output current is 0 to 500 mA. |
| 8 | OUT | power_out | Power-switch output (pin 8 is internally tied with pins 6 and 7); recommended continuous output current is 0 to 500 mA. |

## CAD (KiCad official)

- Symbol: `TPS2041BD`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `tps2041bd-etched.step` / `tps2041bd-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps2041bd.step` / `tps2041bd.glb` are the bare package body.
