BTS4175SGA 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 for the device logic; the logic ground is independent from the load ground, and the device turns OFF or stays OFF on loss of module ground regardless of the IN voltage. |
| 2 | IN | input | CMOS-compatible channel input that switches the channel ON on a logic high level; the input pin is rated for -10 V to 16 V and ±5 mA through the input pins. |
| 3 | OUT | output | Protected high-side power output that drives the load; the drain-source clamp limits the negative output voltage to VS - VDS(AZ) (59 V to 63 V) and the load current is limited to IL(LIM) during overload. |
| 4 | ST | output | Diagnostic feedback of channel status as an active-low open-drain output that requires an external pull-up (a suggested 15 kΩ) to the logic supply and is zener-limited to 5.4 V to 6.1 V when high. |
| 5 | VS | power_in | Battery voltage supply pin (operating range 6 V to 52 V); the wiring should be designed for the simultaneous maximum short-circuit current and for low thermal resistance. |
| 6 | VS | power_in | Battery voltage supply pin (operating range 6 V to 52 V); the wiring should be designed for the simultaneous maximum short-circuit current and for low thermal resistance. |
| 7 | VS | power_in | Battery voltage supply pin (operating range 6 V to 52 V); the wiring should be designed for the simultaneous maximum short-circuit current and for low thermal resistance. |
| 8 | VS | power_in | Battery voltage supply pin (operating range 6 V to 52 V); the wiring should be designed for the simultaneous maximum short-circuit current and for low thermal resistance. |
