## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | S | passive | SOURCE pin of the P-channel MOSFET; pins 1, 2 and 3 are all source and are tied together internally in the datasheet's pinning table, with the absolute maximum VDS of -30V applying across drain and source. |
| 2 | S | passive | SOURCE pin of the P-channel MOSFET; the datasheet lists it as one of the three source pins (1, 2, 3) with a maximum rating of VDS = -30V. |
| 3 | S | passive | SOURCE pin of the P-channel MOSFET; the datasheet lists it as one of the three source pins (1, 2, 3) with a maximum rating of VDS = -30V. |
| 4 | G | input | GATE pin of the P-channel MOSFET; the absolute maximum gate-source voltage is VGS = ±25V. |
| 5 | D | passive | DRAIN pin of the P-channel MOSFET; the device is rated for continuous drain current ID = -14A at TA=25°C and -11A at TA=70°C. |
| 6 | D | passive | DRAIN pin of the P-channel MOSFET; the datasheet lists it as one of the four drain pins (5, 6, 7, 8) with continuous drain current ID = -14A at TA=25°C. |
| 7 | D | passive | DRAIN pin of the P-channel MOSFET; the datasheet lists it as one of the four drain pins (5, 6, 7, 8) with continuous drain current ID = -14A at TA=25°C. |
| 8 | D | passive | DRAIN pin of the P-channel MOSFET; the datasheet lists it as one of the four drain pins (5, 6, 7, 8) with continuous drain current ID = -14A at TA=25°C. |
