**Infineon Technologies** · Power Distribution Switches · SOIC-8

BSP772TXUMA1 from Infineon Technologies, 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 | Logic ground (signal GND reference for the input). |
| 2 | IN | input | Input, activates the power switch in case of logic high signal; CMOS compatible. |
| 3 | OUT | output | Output to the load. |
| 4 | NC | unconnected | Not connected. |
| 5 | Vbb | power_in | Positive power supply voltage, operating range 5...34 V. |
| 6 | Vbb | power_in | Positive power supply voltage, operating range 5...34 V. |
| 7 | Vbb | power_in | Positive power supply voltage, operating range 5...34 V. |
| 8 | Vbb | power_in | Positive power supply voltage, operating range 5...34 V. |
