**Texas Instruments** · Power Distribution Switches · SC-70-5

TPS22941DCKR from Texas Instruments, in a SC-70-5. 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 | VOUT | power_out | Switch output; place ceramic bypass capacitor(s) between this terminal and GND. |
| 2 | GND | power_in | Ground. |
| 3 | OC | output | Over current output flag; active LOW open drain output indicating over current, supply under voltage, or over temperature state. |
| 4 | ON | input | Switch control input; do not leave floating. |
| 5 | VIN | power_in | Switch input voltage; place ceramic bypass capacitor(s) between this terminal and GND. |
