BTS4300SGAXUMA1 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 | Ground connection; the logic ground is independent from the load ground. |
| 2 | IN | input | Input channel; a logic high level activates the channel, and the input accepts -10 V to 16 V with input current limited to -5 mA to 5 mA. |
| 3 | OUT | power_out | Protected high-side power output channel that drives the load and is clamped to VS - VDS(AZ), with VDS(AZ) of 41 V min. and 47 V typ. |
| 4 | ST | output | Diagnostic feedback of the channel; open-drain, active-low status output that requires an external pull-up (a suggested value is 15 kΩ) and is clamped to 5.4 V to 6.1 V at 1.6 mA. |
| 5 | VS | power_in | Battery voltage with an operating range of 5 V to 34 V; the wiring must be designed for the simultaneous maximum short-circuit current and for low thermal resistance. |
| 6 | VS | power_in | Battery voltage with an operating range of 5 V to 34 V; the wiring must be designed for the simultaneous maximum short-circuit current and for low thermal resistance. |
| 7 | VS | power_in | Battery voltage with an operating range of 5 V to 34 V; the wiring must be designed for the simultaneous maximum short-circuit current and for low thermal resistance. |
| 8 | VS | power_in | Battery voltage with an operating range of 5 V to 34 V; the wiring must be designed for the simultaneous maximum short-circuit current and for low thermal resistance. |
