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

TPS2066DGN from Texas Instruments, in a MSOP-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 that is internally connected to PowerPAD for thermal heat-sinking to circuit board. |
| 2 | IN | input | Input voltage supply pin with operating range 2.7V to 5.5V. |
| 3 | EN1 | input | Enable input for OUT1 power switch; logic high turns on IN-OUT1 switch. |
| 4 | EN2 | input | Enable input for OUT2 power switch; logic high turns on IN-OUT2 switch. |
| 5 | OC2 | output | Overcurrent output for OUT2, open-drain active-low signal with threshold range 1.1A to 1.9A. |
| 6 | OUT2 | output | Power-switch output for OUT2 rated for continuous current 0 to 1A with 70mΩ on-state resistance. |
| 7 | OUT1 | output | Power-switch output for OUT1 rated for continuous current 0 to 1A with 70mΩ on-state resistance. |
| 8 | OC1 | output | Overcurrent output for OUT1, open-drain active-low signal with threshold range 1.1A to 1.9A. |
